(57) Abstract: The present invention provides a catheter which combines the benefits of improved drug dispersion, increased ac- curacy of placement and kink and collapse resistance. The catheter comprises a flexible cylindrical tube having a proximal portion open at one end and a distal portion, the portions in fluid communication, the distal portion comprising a closed, rounded tip and a diffusion area having at least one opening therein which permits fluid flow, the proximal portion including a proximal tip, and at least one reinforcement member attached at the distal tip and at the proximal tip of the flexible cylindrical tube, with the remainder of the at least one reinforcement member movable within the flexible cylindrical tube. The catheters of the present invention can find use in a variety of local, regional and peripheral pain management applications.

L'invention concerne un cathéter qui combine les avantages suivants. Il permet une dispersion améliorée du médicament, une précision accrue de placement et présente une résistance accrue au pliage et à l'affaissement. Ledit cathéter est constitué d'un tube cylindrique souple doté d'une partie proximale ouverte à une extrémité et d'une partie distale, parties en communication fluidique l'une avec l'autre. La partie distale comprend une pointe arrondie fermée et une zone de diffusion comportant au moins une ouverture permettant l'écoulement de fluide, la partie proximale présentant une pointe proximale. Ledit cathéter comprend également au moins un élément de renfort fixé à la pointe distale et à la pointe proximale du tube cylindrique souple, le reste du ou desdits éléments de renfort étant mobile dans le tube cylindrique souple. Les cathéters de l'invention peuvent s'utiliser dans une grande variété d'applications de gestion de la douleur périphérique, régionale ou locale.
