CA 2230623

An expander member 12 for a balloon catheter 10 to be used in stent delivery applications comprises a double-walled tubular member that is adapted for attachment to a distal end portion of an elongated, flexible, tubular catheter body. The outer wall 30 is preferably a polyamide, such as Nylon-12, and the inner wall 28 is PET. By properly controlling the percentage of the polyamide relative to the PET content, the distension characteristics of the resulting expander member can be tailored to fall in a range less than 15 percent. The outer Nylon-12 layer 30 provides the expander member 12 with high abrasion resistance. By appropriately temperature annealing the expander member, any tendency toward winging upon deflation thereof is reduced.

Élément d'expansion 12 pour un cathéter à ballonnet 10 devant être utilisé dans des applications d'installation d'un extenseur et comportant un élément tubulaire doté d'une double paroi qui est adapté en vue de sa fixation à une extrémité distale d'un cathéter tubulaire allongé flexible. La paroi extérieure est faite préférablement d'un polyamide, comme un Nylon-12, et la paroi intérieure 28, de PET. En contrôlant convenablement le pourcentage du polyamide par rapport du contenu en PET, les caractéristiques de distension de l'élément d'expansion qui en résulte peuvent être établies pour se situer dans un intervalle de moins de 15 %. La paroi externe de Nylon 12 30 assure à l'élément d'expansion 12 une haute résistance à l'abrasion. En recuisant convenablement l'élément d'expansion, toute tendance à plisser lors du dégonflement est réduite.
