Title (EN) STENTS FOR BODY LUMENS EXHIBITING PERISTALTIC
(FR) DISPOSITIF D'EXPANSION POUR PASSAGES CORPORELS A MOUVEMENT PERISTALTIQUE
Abstract:
(EN) A stent (100) for reinforcement of the lumen of a peristaltic organ, and methods for forming, shaping and heat-treating of such a stent. The stent (100) is formed by knitting preferably a nitinol wire into a pattern of overlapping loops selected such that from a relaxed state each row of loops may shift axially relative to and independently of the rows on either side. A stent is also shown which comprises two resilient cylindrical mesh layers (532, 534) and a semi-permeable compliant membrane (530) such as expanded polytetrafluoroethylene, sandwiched between. A method is also shown of manufacturing a delivery system for a resilient tubular device such as a stent so that the device can be inserted into the body in a substantially reduced diameter.
(FR) Dispositif d'expansion (100) destiné à renforcer la lumière d'un organe péristaltique et procédé de fabrication, de mise en forme et de thermo-traitement de celui-ci. Le dispositif (100) est fabriqué par tricotage de préférence d'un fil de nitinol selon une configuration de boucles chevauchantes choisies de telle manière qu'à l'état lâche, chaque rangée de boucles peut se déplacer axialemnt par rapport aux rangées de boucles adjacentes et indépendamment de ces rangées. Un dispositif qui comporte deux couches (532, 534) de mailles cylindriques souples et une membrane (530) adaptée semi-perméable telle que du polytétrafluoroéthylène expansé placée en sandwich entre les deux couches de mailles est décrit. Un procédé de fabrication d'un système d'acheminement pour un dispositif tubulaire souple tel que ce dispositif d'expansion, de manière à ce que ledit dispositif puisse être introduit dans le corps avec un diamètre considérablement réduit est également décrit.
