Disclosed are systems for removing embolic material from an intravascular site. An elongate, flexible tubular body has a tubular side wall defining at least one axially extending lumen. An axial restraint is carried by an inner surface of the side wall and exposed to the lumen. A rotatable core wire is extendable through the lumen, and may include an obstruction engaging tip. The core wire has a limit with a distally facing bearing surface for rotatably engaging the restraint. The limit and the restraint are configured to permit rotation of the core wire but limit distal advance of the tip to a predetermined relationship with the distal end of the tubular body.
La présente invention concerne des systèmes d'élimination de matériau embolique d'un site intravasculaire. Un corps tubulaire flexible allongé a une paroi latérale tubulaire définissant au moins une lumière s'étendant axialement. Une retenue axiale est portée par une surface interne de la paroi latérale et exposée à la lumière. Un fil central rotatif peut s'étendre à travers la lumière et peut comprendre une pointe de mise en prise d'obstruction. Le fil central a une limite avec une surface d'appui tournée au plan distal pour venir en prise de manière rotative avec la retenue. La limite et la retenue peuvent être conçues pour permettre la rotation du fil central mais limiter l'avancée distale de la pointe à une relation prédéfinie avec l'extrémité distale du corps tubulaire.
