Title
(EN) MAGNETIC ANASTOMOSIS DEVICE WITH AN EMBEDDED DRAINAGE MECHANISM
(FR) DISPOSITIF D'ANASTOMOSE MAGNÉTIQUE AVEC MÉCANISME DE DRAINAGE INTÉGRÉ
Abstract
(EN)
An anastomosis device includes magnets coupled to a wire capable of changing shape from a straight wire into a coil when deployed within a body. The coil exerts compressive force upon layers of tissue caught between loops of the coil. The compressive force is enhanced by attractive forces between magnets coupled with adjacent loops of the coil and causes the coil to cut through the tissue layers, creating an anastomosis. One end of the wire is preferably provided with a connecting member, such as a screw or a nut, for connecting with a delivery device. Positioned on or around the anastomosis device is an expandable drainage mechanism, such as a stent.
(FR)
L'invention concerne un dispositif d'anastomose comprenant des aimants couplés à un fil apte à changer de forme d'un fil droit en une bobine lorsqu'il est déployé à l'intérieur d'un corps. La bobine exerce une force de compression sur des couches de tissu prises entre des boucles de la bobine. La force de compression est améliorée par des forces attractives entre des aimants couplés à des boucles adjacentes de la bobine et amène la bobine à couper à travers les couches de tissu, créant une anastomose. Une extrémité du fil est de préférence pourvue d'un élément de liaison, tel qu'une vis ou un écrou, pour être relié à un dispositif de distribution. Un mécanisme de drainage extensible, tel qu'une endoprothèse, est positionné sur ou autour du dispositif d'anastomose.
