This is a delivery catheter assembly used typically, but not exclusively, in the peripheral vasculature of the human body. The catheter is configured in such a way that the lumen is exceptionally large and the catheter wall is exceptionally thin for a catheter of this class. The distal portion of the catheter contains a kink-resisting member, preferably a super-elastic alloy ribbon braid, which is embedded in the catheter wall. Proximally of the kink- resisting member, the catheter typically will have no other kink-resisting members. Finally, the catheter assembly uses long conical joints between component tubular members to provide smooth and strong transitions between those members.

L'invention concerne un ensemble cathéter d'apport généralement utilisé, mais pas uniquement, dans le système vasculaire périphérique du corps humain. Ce cathéter est conçu de manière à ce que la cavité soit exceptionnellement large et la paroi du cathéter exceptionnellement fine pour un cathéter de ce type. La partie distale de ce cathéter contient un élément résistant au tortillement, de préférence une tresse en ruban en alliage super élastique, enchâssée dans la paroi dudit cathéter, qui ne présente généralement aucun autre élément résistant au tortillement sur sa partie proximale. Cet ensemble cathéter utilise en outre de longs joints coniques pour relier de manière à la fois souple et solide différentes composantes tubulaires dudit cathéter.
