Title (EN) IMPROVED MULTI-DUROMETER CATHETER
(FR) CATHETER MULTIDURETE PERFECTIONNE
Abstract:
(EN) Improved multi-durometer catheter (10) and method of making said catheter (10) is disclosed. One catheter (10) of the invention includes proximal segment (20), distal segment (30), and elongate tubular reinforcing member (40) which is imbedded into inner surface of the proximal segment (20) along a distal length thereof, and is imbedded into an inner surface of the distal segment (30) along a proximal length thereof. Distal end (26) of proximal segment (20) is joined to proximal end (36) of the distal segment (30). The durometer of the plastic of proximal segment (20) may be greater than the durometer of the plastic of distal segment (30). In one method, catheter (10) is made by forming tubular proximal segment (20), tubular distal segment (30), and elongate tubular reinforcing member (40). Reinforcing member (40) is then imbedded into an inner surface of proximal segment (20) along a distal length thereof, and imbedded into an inner surface of distal segment (30) along a proximal length thereof. Distal end (26) of proximal segment (20) is joined to proximal end (36) of the distal segment (30).
(FR) L'invention concerne un cathéter multidureté perfectionné (10) et son procédé de fabrication. Ce cathéter (10) comporte un segment proximal (20), un segment distal (30), et un élément de renforcement tubulaire allongé (40) qui est noyé dans une surface intérieure du segment proximal (20) sur sa longueur distale et est noyé dans une surface intérieure du segment distal (30) sur sa longueur proximale. L'extrémité distale (26) du segment proximal (20) est reliée à l'extrémité proximale (36) du segment distal (30). La dureté du plastique du segment proximal (20) peut être supérieure à celle du plastique du segment distal (30). Dans un procédé, le cathéter (10) est réalisé par formation d'un segment proximal tubulaire (20), d'un segment distal tubulaire (30) et d'un élément de renforcement tubulaire allongé (40). L'élément de renforcement (40) est ensuite noyé dans une surface intérieure du segment proximal (20) sur sa longueur distale, et noyé dans une surface intérieure du segment distal (30) sur sa longueur proximale. L'extrémité distale (26) du segment proximal (20) est reliée à l'extrémité proximale (36) du segment distal (30).
