Title
(EN) SELF-EXPANDING CARDIOVASCULAR OCCLUSION DEVICE
(FR) DISPOSITIF AUTO-EXTENSIBLE POUR OCCLUSION CARDIO-VASCULAIRE
Abstract
(EN) A self-expanding cardiovascular occlusion apparatus (20) including a predetermined pattern of wire (22) and three collinear bands,whereby pushing the bands together causes the two exposed braided or helical sections between them to flatten to two disk-like shapes (130, 132). The disks (130, 132) are then forced outward relative to the middle band (125) causing the exposed braided or wound pattern to invaginate. The final shape is similar to two cones attached end to end. The device (20) is heat treated to maintain this configuration. In use, the device (20) is straightened to its cylindrical form, installed in the distal end of a device pusher (40) which is advanced through a small diameter catheter installed in a blood vessel (46). When the device is expelled from the device pusher (40), it returns to its expanded shape and lodges in a blood vessel (46), for example. Once lodged in the vessel, the device will initiate thrombus formation which will occlude the vessel. The final in situ form of the device with cone-like ends has the ability to adapt to a range of vessel sizes.
(FR) Cette invention concerne un dispositif auto-extensible pour occlusion cardio-vasculaire (20) comportant un réseau préétabli de fils métalliques (22) et trois bandes colinéaires qui, lorsqu'on les pousse conjointement, provoquent l'aplatissement des parties tressées ou hélicoïdales exposées, disposées entre ces bandes, en deux formes ressemblant à des disques (130)(132). Ces disques (130)(132) sont ensuite poussés vers l'extérieur par rapport à la bande centrale (125) ce qui entraîne l'invagination de la structure tressée ou enroulée exposée. La forme finale ressemble à deux cônes attachés bout à bout. Ledit dispositif (20) subit un traitement thermique qui lui permet de conserver sa structure. En cours d'utilisation, on étire ledit dispositif (20) pour lui donner sa forme cylindrique, on l'installe à l'extrémité distale d'un pousse-dispositif (40) que l'on fait avancer dans un cathéter de faible diamètre disposé dans un vaisseau sanguin (46). Lorsque le dispositif (20) est expulsé du pousse-dispositif, il reprend sa forme détendue et il se loge, par exemple, à l'intérieur d'un vaisseau sanguin(46). Une fois installé à l'intérieur du vaisseau, ledit dispositif initie la formation d'un thrombus destiné à obstruer le vaisseau. La forme finale qu'adopte, in situ, le dispositif à extrémités coniques, permet l'adaptation dudit dispositif à toute une gamme de tailles de vaisseaux.
