Title (EN) STENT DELIVERY SYSTEM
(FR) SYSTEME DE PLACEMENT D'EXTENSEUR
Abstract:
(EN) What is disclosed is a stent delivery system comprising an inflation shaft having an expandable balloon sealingly mounted at the distal end thereof and a tubular sheath having the inflation shaft longitudinally running therethrough. The tubular sheath has an expandable sheath at the distal end thereof with the balloon longitudinally running therethrough and an expandable stent mounted on the expandable sheath. Also disclosed is a method of delivering a stent into a body lumen. The method comprises the steps of providing an inflation shaft having an expandable balloon sealingly mounted at the distal end thereof and providing a tubular sheath having the inflation shaft longitudinally running therethrough. The expandable sheath has the balloon longitudinally and slidingly running therethrough, and an expandable stent is mounted on the expandable sheath. The stent is positioned in the body lumen at the treatment site and the balloon is inflated simultaneously with the expandable sheath to deploy the stent.
(FR) L'invention concerne un système de placement d'extenseur, comprenant une tige de gonflement pourvue d'un ballonnet expansible monté hermétique sur l'extrémité distale de cette tige, et une gaine tubulaire, à travers laquelle passe longitudinalement ladite tige de gonflement. L'extrémité distale de ladite gaine tubulaire présente une gaine expansible, à travers laquelle passe longitudinalement ledit ballonnet; un extenseur expansible est également monté sur cette gaine. L'invention concerne également un procédé de placement d'un extenseur dans une lumière corporelle. Ce procédé consiste à délivrer une tige de gonflement pourvue d'un ballonnet expansible, monté hermétique sur l'extrémité distale de cette tige, et constituant une gaine tubulaire à travers laquelle passe longitudinalement ladite tige de gonflement. Le ballonnet passe longitudinalement et de manière coulissante à travers ladite gaine expansible, un extenseur expansible étant monté sur cette gaine expansible. Cet extenseur est placé sur le lieu de traitement de la lumière corporelle, et le ballonnet gonflé simultanément à la gaine expansible, de manière à déployer ledit extenseur.
