Title (EN) STENT RETRIEVAL DEVICE
(FR) DISPOSITIF DE RECUPERATION D'EXTENSEUR
Abstract:
(EN) A device and method for retrieving a stent from the vessel of a patient includes a catheter which is formed with a central lumen that defines a passageway having a diameter. A deformable distal tip is attached to the catheter to establish an extension of the passageway. In the operation of the device, the distal tip is initially maintained in a first configuration wherein the stent can be received into and through the passageway. While the distal tip is maintained in this first configuration, a portion of the stent to be retrieved is withdrawn into the passageway of the distal tip. The distal tip is then distended or deformed into a second configuration wherein the diameter of the passageway is reduced to grip the stent. The catheter and the gripped stent are then retrieved from the vessel of the patient.
(FR) La présente invention concerne un dispositif et un procédé de récupération d'un extenseur depuis un vaisseau d'un patient. Le dispositif comporte un cathéter dont la forme présente une lumière centrale définissant un passage caractérisé par un diamètre. Une extrémité distale déformable pouvant se fixer sur le cathéter est capable de produire un élargissement du passage. Pour la mise en ÷uvre du dispositif, on commence par maintenir l'extrémité distale dans une première configuration permettant à l'extenseur de pénétrer dans le passage et de le traverser. Le procédé consiste, pendant que l'on maintient l'extrémité distale dans cette première configuration, à tirer dans le passage de l'extrémité distale une partie de l'extenseur à récupérer. Le procédé consiste ensuite à détendre ou déformer l'extrémité distale jusqu'à ce qu'elle prenne une seconde configuration selon laquelle le diamètre du passage est réduit pour saisir l'extenseur. Le procédé consiste enfin à retirer du vaisseau du patient le cathéter et l'extenseur saisi.
