The present invention relates to a kit for closin~ the
intestinal opening on an an~s practer patient.
There are many colostomy and ileostomy paticnts who
have an intestinal opening in ~heir abdominal wall. The use of
natural or artifical sphincters Ln such a location is impossibl~.
- The normal expedient is to close the opening by a special dressing
or by wearing a was~e bag.
The concept of this invention is to provide a reliable
seal and/or to hold the waste bag by means o~ ma~netic action.
Accordingly, a permanen~ ma~net, a magnet sys~em, a soft magrleti.c
material or a similar device is provided .~or ~itting around the
intestillal opening, ~hile a matching counterpart mad~ of permanent
or soft magnetic material provides for the closing o~ this
opening by magnetic action. The term "magneti.c action" is to be
,~ understood to m~an anything which is activatecl by magnetic forces,
I for instance attraction, rep~tlsion or spreading o~ the respective
parts in relatioll to the int~stinal opening. The term "magne~ic
system" means a plurality o- permanent magnets and/or so~t
magnetic material acting ~ogethcr. The term l'~ot magl~etlc
material" means a material which is ma~netizable or whi.ch
becomes attracted by a magnet, but does not retai.n magnetism.
.1 The kit, according to this inventioll, includes a rirlg-
.~ shaped permanen~ magnet, ~ith radial, axi.al or multi-p~le
magnetiæation~ to be implanted under the abdominal wall and
~itted around the in~estinal opening. The kit also includes a
waste bag or sealing cap, the inlet of the waste bag and the
sealing cap havin~ a similar permallent or sot magnetic ringS or
a matching Magnetlc system, incorporate~ therein. The respective
. m.agnets n~ay ~e in one i)iece, com~)ose~l o~ ~;cgnlents, ctc. p~3

Any known type of magnet can be em~loyed to achieve the
cleslred action.
The Lnvention will be ~escribed further, by w~y o~ :~
example, with reference to the accompanyillg drawing, in which:
Fig. 1 is a diagra~na~ic cross-sec~ional side elevational
view showing a preferred embodimen~ of the device of the Lnvention
appropria~ely fit~ed in place in a patient and with a waste bag
I inserted in posi~ion;
Fig, 2 is an elevational view illustrating diagrammatically
the magnetization of the permanent magnet of ~he device of Fig. l; c~ :
Fig. 3 is a view similar to Fig. 2 but illustratln~ an :`
alternative way in whi.ch the magnet may be magnetizecl;
Fig. 4 is a view comparable with Fig. l but showing a
. slightly modifi~d embodiment and with a sealing cap bein~ put in
:l place; and
Fig. S is a graph illustrating the magnetic advantage :~
obtained with the embodiment of Fig. 4.
Referrillg fi.rst to Figs. 1 and 4, implanted under
abdominal wall 1 of a patient and around i.ntes~lne 2 i9 a ring
magnet 3. Waste bag 4 has an inle~ S in ~he ~orm o~ a soft
magnetic or a permanent magnetic ring. .The ring S is ~hus urged
into ring 3, and is retained ther~in by magnetic actioll.
.' Figs. 2 and 3 show alterna~ive magnetiza~iQns for ~he ~:
implanted magnet 3. Otller magnetizat~ons ~re also possible,
: such as axial nagnetization for the ring magnet 3 and its ::
counterpart ring 5. :,
It i.s possible to use a sealing cap instea~ of the
waste bag. Fig. 4 shows a sealin~, c~p 10 m~cle of non-magnetic
,. .
l~t5é~
il msterlal h Lch has a dlsc-shaped portioll 6a and a cyllnclrical
, portion 9 pro~ecting ther~fr~m. Ring magllet 6b, which is similar
j to the implanted ring magnet 3a, is located in dLsc-stlap~d
portion 6, and core magnet 8 is loca~ed in cyli1der 9. The
. cen~er core ma~net 8 increases the magnetic a~tractlon b~tween
-- . the implanted magnet 3a and ~he magnets 6b, 8 in the sealing cap
: 10 when spaced a wide distance ~say, 10 to 20 mm) from magnet 3~,
; and reduces ~hls magnetic attrac~ion at a close dlstance (say,
. 3 to 7 rNm)~ Thus, the force versus distance characteristic is
~ 10 improved. ~'ig. 5 shows this characteristic with ~he ~ull line
representing cap 10 with the center core magnet 8 and the dotted
line representing cap 10 without magnet 8.
While core magnet 8 is shown in Fig. 4 as b~ing
permanently embedded in cylinder 9, i~ is apparent that the
cap 10 can be provided with means (not shown) for axially
adjusting the positiol of core magnet 8, e.g. towards or away
from disc-shaped portion 6b. Suitable axial a~justmerlt means
include an adjusting screw for moving or tiltlng the core magnet
8 to the desired position or for sliding the magn~t 8 towar~s or
away ~ronl disc-sllape(l portion 6b.
When using a waste bag held by alearls of n~agnetic action,
the magnet or the sof~ magnetic part o~ the bag may be ma~le in a
way that upon discarding the bag the magne~ or the soft magnetic
~art can be used again.
In order to provide safe and non-skin irritating
s~aling both for the bag and the sealing cap, a suitable gasket 7,
made for example ou~ of moisture-adsorbil~ ma~erial and/or a soft
~j resi is advantageously placed bet~een the bar or cap an~l the
105;~109 ~ ~
abclomin 1 wa~l. This gasket 7 may contain medicaments Dt an
an~ibiotic and/or scent suppressing and/or other nature.
In addition, be~ore implantation~ magnets 3 and 3a may
be embedded in a material acceptable to human tissue, such as
silicone, polyethylene, polyes~er and the like.
The term l'anus praeter" is used herein to mean an
artificial outlet on the front of the body, such as an artificial ~ :
intestinal outlet or opening. An "anus prae~ex" is also referred
to as ~'stoma~', and th- ter~s are intcrc arg able
