IMPROVED TE~EMETRY FORMAT
BACKGROUND OF THE INVENTION
Field of the Invention.
The present invention generally relates to
5 implantable medical devices, and more particularly,
pertains to telemetry schemes for percutaneously
transmitting analog and digital data from an implantable
medical device.
Description of the Prior Art.
The earliest implantable medical devices were
designed to operate in a single mode and with no direct
percutaneous communication. Later it became clinically
desirable to vary certain of the operating parameters and
chanqe modes of operation. This was accomplished through
15 the use of programmers and other external devices which
transferred commands percutaneously to the implanted
medical device.
The communication between the implant and the
external world was at first primarily indirect. The
20 operation of an implantable cardiac pacer could be
observed, for example, in the electrocardiogram of the
patient. Soon it became known that data could be sent
from the implanted cardiac pacer by modulating the
stimulation pulses in some manner. This can only provide
25 a low bandpass channel, of course, without interfering
with the clinical application of the device. Change of
the pacing rate to indicate battery condition was a
commonly used application of this technique.
As implantable cardiac pacers became more complex,
30 the desirability to transfer more data at higher speeds
resulted in the percutaneous transmission of data using a
radio frequency carrier. The data to be transmitted is
of two basic types, namely, analog and digital. The
analog information can include, for example, battery
35 voltage, intracardiac electrocardiogram, sensor signals,
output amplitude, output energy, output current, and lead
impedance. The digital information can include, for

example, statistics on performance, markers, current
values of programmable parameters, implant data, and
patient and unit identifiers.
The earliest RF telemetry systems transmitted analog
5 and digital information in separate formats, resulting in
inefficient utilization of the available power/bandwidth.
Also, these modulation schemes tended to be less than
satisfactory in terms of battery consumption, and do not
lend themselves to simultaneous transmission of differing
l0 data types.
Many types of RF telemetry systems are known to be
used in connection with implantable medical devices, such ~;
as cardiac pacemakers. An example of a pulse interval
modulation telemetry system used for transmitting analog
15 and digital data, individually and serially, from an
implanted pacemaker to a remote programmer is disclosed
in U.S. Patent No. 4,556,063 issued to Thompson et al.,
herein incorporated by reference. An example of a modern
pacemaker programmer for use with programmable cardiac
20 pacemakers having RF telemetric capabilities is disclosed
in U.S. Patent No. 4,550,370 issued to Baker, herein
incorporated by reference. However, the telemetry format
which is used under these systems, as well as other prior
telemetry systems, have not been entirely adequate for
25 reasons described above and a need for significant
improvement has continued. As will become apparent from ,
the following, the present invention satisfies that need.
SUMMARY OF THE INVENTION
The present invention percutaneou~ly transmits all
30 data from the implantable medical device in a digital
format. It is pulse position modulated on an RF carrier.
To accomplish this, the analog quantities must be
converted to digital values either at the time of
transmission, such as for real-time intracardiac
3S electrocardiograms, or before storage in the memory of
.

the device, as in the case of historical values of pacing
rate for subsequent transmission for trend analysis.
Whether the data to be sent is initially analog or
digital, it is transmitted in the same format, i.e., as
S digital information. The RF carrier is pulse position
modulated to conserve battery energy. In this manner,
only a short burst of the carrier, e.g., one cycle, is
actually needed to transmit a given unit of data. The
time position of that burst relative to a synchronizing
10 standard determines the value of the data unit
transmitted.
To accomplish this pulse position modulation, a
frame of about 2 milliseconds is defined. Within this
frame are positioned a synchronizing burst, a frame
15 identifier burst, and one or more data bursts. The
synchronizing burst is positioned at a fixed position in
the frame. The frame identifier and data are variables,
such that the corresponding bursts occur within a range
of time within the frame. The range in which a burst is
20 found defines the nature or type of the variable. The
position in the range defines the value of the variable.
Because all data transmission is in a digital
format, great flexibility is achieved with regard to
additional units of data for future applications. The
25 use of the standardized format and capability of encoding
more data into a single pulse also decreases the overall
battery current requirements and serves to level the
energy demand over time. Transmitting the analog data in
digital form provides enhanced noise immunity and
30 accuracy.
The transmiscion protocol provides data rates which
are sufficient to transfer clinically useful EGM
information in real time. Because each frame is
independent, data quantities of varying precision can be
35 transmitted using the same protocol. This modulation
scheme provides flexibility of use, for example, with

complex medical devices where transmission of increased
volumes of data is desirable in real time, such as
cardiac devices having dual-chamber or multisensor
capabilities, and for controlling particular conditions
5 such as tachyarrhythmia.

DETAILED DESCRIP~ION OF THE PREFERRE~ EMBODIMENTS
A preferred embodiment of the present invention is
disclosed relating to use of the improved telemetry
format with an implantable cardiac pacer, which may be
5 programmable. However, those of skill in the art will be
readily able to adapt the teachings found herein to other
implantable medical devices. It will also be understood
by those of skill in the art that the telemetry format
taught herein can be used for bi-directional
l0 communications between an implanted medical device and an
external device.
FIG. l is a simplified schematic diagram of the
present invention as employed in a cardiac pacing system.
An implantable pulse generator l0 is implanted in the
15 patient under the outer skin barrier 28. Implantable
pulse generator l0 is electrically coupled to the heart
of the patient using at least one cardiac pacing lead 12
in a manner known in the art. Percutaneous telemetry
data is transmitted from implantable pulse generator l0
20 by an RF uplink 26 utilizing the improved telemetry
format to a receiving antenna 22, which is coupled to a
programmer 20 via a cable 24. Receiving antenna 22 also
contains a magnet which activates a reed switch in
implantable pulse generator l0 as a safety feature, as
25 taught in U.S. Patent No. 4,006,086 issued to Alferness
et al., herein incorporated by reference. The telemetry
data is demodulated and presented to the attending
medical personnel by programmer 20.
- FIG. 2 is a schematic diagram of the protocol of RF
30 uplink 26 using the improved telemetry format. The
uplink uses a damped 175 kilohertz RF carrier which is
pulse position modulated, as described in detail below.
Shown at 30, the basic timing unit of the format is a
frame, having a duration of t~. It will be understood by
35 those skilled in the art, however, that the present
invention can be practiced using fixed-length frames

having periods of shorter or longer duration. In the
preferred embodiment, the main timing source of
implantable pulse generator lO comprises a standard
32.768 kilohertz crystal clocX which provides a basic
5 clock cycle of 30.52 microseconds. Thus, a frame
comprised of 64 clock cycles and extending over a fixed
time interval of l.953125 milliseconds is a convenient
frame period, since such frame period is a binary
multiple of the basic clock cycle.
A unique synchronizing signal is positioned within a
first fixed range of each frame 30. This signal
comprises a synchronizing RF pulse 32 which is located at
a time tn1 within frame 30. To properly function as a
synchronizing pulse, it must be located at a fixed point
l5 within the first fixed range of frame 30, as shown at 34. ;
A four-bit frame identifier code is positioned
j within a second fixed range of each frame 30, such second
fixed range comprising an identifier range 38.
Identifier range 38 uses a total of eleven basic clock
20 cycles as shown. This identifier code comprises an
identifier RF pulse 36 which is pulse position modulated
within the identifier range 38. The position of
identifier pulse 36 within identifier range 38 identifies
the nature or type of data found within each frame 30 ?
; 25 which is being transmitted, such as peak sense, peak
pressure, sense threshold and others, as described in
further detail below. Shown at 40, time interval t~ thus
uniquely represents the value of identifier pulse 36,
which value in turn identifies the data type being
30 transmitted within frame 30.
Each frame 30 transfers one eight-bit byte of data
along with the identifier code. This data is divided
into two portions comprised of four bits of data each. A
first portion of this data, namely the four least
35 significant bits of the data byte, is positioned within a
third fixed range of frame 30, such third fixed range

comprising a lower nibble range 44. A second portion of
this data, namely the four most significant bits of the
data byte, is positioned within a fourth fixed range of
frame 30, such fourth fixed range comprising an upper
5 nibble range 48.
A lower nibble pulse 42 is pulse position modulated
within lower nibble range 44, such that its value is
uniquely identified by its location, such as at a time t~
shown at 45. An upper nibble pulse 46 is also pulse
lO position modulated within upper nibble range 48, such
that its value is uniquely identified by its location,
such as at a time t~ shown at 50. Lower nibble range 44
and upper nibble range 48 each comprise sixteen basic
clock cycles, permitting each of the sixteen unique
15 values of the four-bit nibble to be specified. To
prevent data overlap, suitable guardbands are positioned
between each of the ranges within the frame to uniquely
identify the synchronizing pulses, thereby avoiding
undefined and erroneous data transmission.
FIG. 3 is a diagram of two frames of RF uplink 26,
wherein a first frame corresponds to Word l shown at 70,
and a second frame corresponds to Word 2 shown at 72. A
count of clock cycles is indicated along an upper
horizontal axis of this diagram for each frame. Each
25 basic clock cycle has a duration of 30.52 microseconds.
The first frame at 70 is initiated by an ~F pulse 52. A
synchronizing RF pulse 54 is shown uniquely identified as
precisely four clock cycles later. Because~the
guardbands are all greater than four clock cycles, no
30 combination of a frame identifier and data can appear as
a synchronizing pulse. Synchronizing pulse 54 is used to
provide frame synchronization between the transmitter
(i.e., implantable pulse generator lO) and the receiver
- (i.e., programmer 20).
An identifier RF pulse 56 is located within
identifier range 38, which range is defined as nine to

nineteen basic clock cycles from the beginning of frame
70. In Word l, for example, identifier pulse 56 is
located at clock cycle nineteen. This identifies the
frame as a particular type of data transfer, namely,

A lower nibble RF pulse 58 is located within lower
nibble range 44, which range is defined as twenty-four to
thirty-nine basic clock cycles from the beginning of
frame 70. In Word l, for example, lower nibble pulse 58
25 is located at clock cycle thirty-one, specifying a binary
value of seven on a scale of zero to fifteen. An upper
nibble RF pulse 60 is located at clock cycle fifty-eight
within upper nibble range 48, which range is defined as
forty-four to fifty-nine basic clock cycles from the
30 beginning of frame 70, and is demodulated in similar
fashion.

unique hardware which embodies the present invention is
located on a single substrate, being a custom chip device
indicated generally by arrow 105. The remainder is
microprocessor-based logic indicated generally by arrow
5 lO0, comprising microprocessor 102, random access memory
(RAM) 104, and parallel bus 106. The function of
microprocessor-based logic 100 is described in further
detail below.
Chip 105 has an analog-to-digital (A/D) converter
10 108 which receives a number of analog inputs 110 from a
multiplexer (not shown). A/D converter 108 permits data
to be transferred~ via RF uplink 26 to be digitized as
necessary, so that all data is transmitted in a
standardized digital form.
Circuitry (CRC) for generating and analyzing the
cyclic redundancy code used to forward error detect
telemetry data transmitted over RF uplink 26 is indicated
~, at 112. In the preferred embodiment, it is also used for
data received by implantaDle pulse generator 10 via a
20 downlink (not shown). Circuitry (DMA) for providing
direct memory access to RAM 104 is indicated at 114, thus
~ permitting multiple byte transfers without constant
!~ management by microprocessor 102.
Key hardware used to implement RF uplink 26
25 comprises telemetry control and data buffer circuitry
indicated generally within dashed lines at 121, which
circuitry includes data buffer 116 and telemetry control
120, and up-link timing circuitry 118. Data buffer 116
includes storage for twelve bits of data. This storage
30 is partitioned into a four-bit section 119 for storage of
the frame identifier code, and an eight-bit section 117
for storage of the lower nibble and upper nibble of a
ç frame. Data buffer 116 thus stores all of the variables
for one complete frame. Data buffer 116 is used to stage
35 the variables for the frame which may be received from

RAM 104, A/D converter 108, CRC 112, or elsewhere along
parallel bus 106.
Telemetry control 120 consists primarily of a
telemetry status register. This register stores the
5 telemetry commands and status as loaded by microprocessor
102. The contents of the register are thus used to gate
the data at the proper time of the defined protocol.
Up-link timing 118 decodes the twelve bits of data
stored in data buffer 116 to produce a set of timing
10 signals which key bursts of RF energy at the appropriate
times to pulse position modulate the 175 kilohertz
carrier. Up-link timing 118 also keys bursts of RF
energy at the fixed positions within the frame
corresponding to the frame-initiating pulse and the
15 synchronizing pulse.
FIG. 5 is a basic flowchart showing the overall
function of the microprocessor-based logic 100. The role
is essentially one of initiation of the transfer, rather ~ .
than management of each detail of the transmission.
20 Software associated with RF uplink 26 is started at
element 130, usually by a down-linked command to transfer
data. ~ -
Element 132 schedules the requested transmission via
the up-link facilities. This scheduling prioritizes
25 uplink transmission requests. Lower priority is given to
continuous real time transfers, such as EGM and battery
voltage, whereas higher priority is given to single
occurrence transmissions of status information.
After scheduling, element 134 determines whether an
30 uplink transmission is currently in progress. If an
uplink transmission is in progress, element 132 re-
schedules the request.
If an uplink transmission is not in progress after
scheduling, element 136 initiates the uplink transmission
35 by activating telemetry control 120. Exit is via element
138. While some additional management of the process is ~;

required during the transmission, a description of such
further details has been omitted, since it is not
believed necessary to one skilled in the art to fully
understand the present invention. As to the software
5 associated with the uplink transmission, however, a
source code listing of the pertinent sections of such
software has been attached hereto as Appendix A, and is
incorporated by reference herein.
FIG. 6 is a block diagram showing the major data and
10 control signals of telemetry control and data buffer 121
(which includes data buffer 116 and telemetry control 120
shown in FIG. 4), and also of up-link timing 118. A
primary function of data buffer 116, as indicated above,
is the staging of the twelve variable bits of a given
15 frame which correspond to a four-bit frame identifier ID,
and dual-nibble data comprising a four-bit lower nibble
LN and a four-bit upper nibble UN. The data is received
over an eight-bit, parallel bus 159 and can be from any
one of several sources. Control lines E~MDATA at 150,
20 PRSDATA at 151, DLDMA at 153, DMADS at 155, LDANDAT at
156, ENCRC at 161 and LDCRC at 171 specify the source.
The output of A/D converter 108 of FIG. 4 is presented
separately to data buffer 116 as an eight-bit parallel
transfer to ADC(0-7) at 154 (see FIG. 6). The output of
25 CRC 112 is presented separately to data buffer 116 as an
eight-bit parallel transfer to CRC(0-7) at 160, since
those devices are located on the same substrate.
Telemetry control 120 outputs a number of control
signals, including EGMGAIN at 162, RVPGAIN at 163,
30 EGMTELEN at 164, ANULON at 165, RAMULON at 166, MEMEN at
167, PRSTELEN at 168, HDRCRCEN at ~69 and EGMNPRS at 170.
These control output~ re used to enable and control
inputs to data buffer 116. The key outputs of telemetry
control and data buffer 121 are TELRST at 182, which
3S resets up-link timing 118 and initiates the beginning of
a frame, and a parallel data transfer at 184, which

transfers the frame identifier ID, lower nibble LN and
upper nibble UN to up-link timing 118.
Up-link timing 118 receives the frame-initiating
control signal TELRST at 182 and the parallel data
5 transfer (ID, LN and ~N) at 184. A primary function of ?
up-link timing 118 is to key the transmission of 175
kilohertz RF energy at the proper times to indicate start
of rrame, frame synchronization, frame identifier, lower
nibble and upper nibble. Timing for this function is
10 provided by the 32.768 kilohertz crystal clock to up-
link timing 118 with clock signal XTAL at 186. An output
TELCLK is provided at 188 which keys the actual burst of
RF carrier at the proper times.
FIG. 7 is a block diagram of up-link timing 118. A
15 frame timing generator 202 provides the desired timing
for a frame according to clock input XTAL at 186, in a
manner hereinabove explained. Thus, each frame is
comprised of sixty-four basic clock cycles. The process
is initiated by receipt of the frame-initiating control
20 signal TELRST at 182, which enables uplink when in a low
state and disables uplink when in a high state. The
initial clock cycle of a frame contains a burst of RF
energy which is keyed by control signal TELCLK at 188,
which is also used to trigger the start of the data
25 decoding by an uplink word multiplexer 200.
After the proper four-bit quantity is selected -:
(i.e., frame identifier ID first, lower nibble ~N next,
; and upper nibble UN last), a telemetry pulse timer 204 -
determines the appropriate timing for a burst to be
30 provided to frame timing generator 202, and a
corresponding burst of RF energy is keyed. Each of the -
four-bit quantities thus results in the keying of a burst
of RF energy at the appropriate time within each frame.
FIG. 8 is a circuit diagram for the drive circuit
35 for generating the RF carrier. A control signal TELCLK

carrier. A non-overlap generator 220 functions as a
delay device to save current by preventing output
transistors 230 and 232 from conducting simultaneously.
Every transition of control signal TELCLK at 188 causes
5 one transition by non-overlap generator 220. Inverters
222, 224, 226 and 228 are scaled to provide efficient
switching with sufficient drive to the gates of
transistors 230 and 232. Transistors 230 and 232 drive
the signal off of chip 105 to ANTDR at 234 to an antenna
lO circuit. A tuned circuit of discreet components,
capacitor 236 and coil 238, are located external to chip
lO5. Each transition thus causes this tuned circuit to
resonate at 175 kilohertz, thereby generating one uplink
burst.
While the invention has been described above in
connection with the particular embodiments and examples,
one skilled in the art will appreciate that the invention
is not necessarily so limited. It will thus be
understood that numerous other embodiments, examples,
20 uses and modifications of and departures from the
teaching disclosed may be made as to various other
systems for telemetering data to and from an implantable
medical device, without departing from the scope of the
present invention as claimed herein.
