CATHETER STIFFENING MEMBER

A stiffening member for providing controllably variable stiffness to a catheter. A hollow elongated tubular member is sized to be received in a lumen of the catheter. At least a length of the tubular member is configured, such as by forming a spiral cut therethrough, in a manner such that the distal...

Beschreibung
Zusammenfassung:	A stiffening member for providing controllably variable stiffness to a catheter. A hollow elongated tubular member is sized to be received in a lumen of the catheter. At least a length of the tubular member is configured, such as by forming a spiral cut therethrough, in a manner such that the distal portion of the tubular member has a greater flexibility than the proximal portion. L'invention concerne un élément de rigidification de cathéter destiné à conférer une rigidité variable au cathéter. Un élément tubulaire allongé creux est dimensionné de façon à être logé dans la lumière d'un cathéter. Au moins une partie longitudinale de l'élément tubulaire est conçue, par exemple par création d'une coupe spirale au travers de cette partie, de manière que la partie distale de l'élément tubulaire présente une flexibilité supérieure à celle de la partie proximale.
