Title
(EN) MULTI-LUMEN CATHETER WITH PROTECTED TIP
(FR) CATHETÉR À LUMIÉRES MULTIPLES AVEC BOUT PROTÉGÉ
Abstract
(EN)
A multilumen catheter assembly (100) including a catheter (102) having an elongated body (108) having a proximal end (104) and a distal end (106) and a first lumen (122) with a first distal opening (126) disposed at its distal end, and a second lumen (124) connected to the first lumen but extending distally therebeyond to a second distal opening (130). A protector (120) is adjoined to the second lumen (124) distally of the first distal opening (126) and extends radially and proximally to a free proximal edge (134) to engage the vessel walls radially about the first distal opening to center the catheter (102) within the vessel to prevent occlusion of the first distal opening (126). A plurality of openings (136) extend through the protector (120) to permit blood flow therethrough.

L'invention concerne un ensemble cathéter à lumières multiples (100) comprenant un cathéter (102) possédant un corps allongé (108) avec une extrémité proximale (104) et une extrémité distale (106) ainsi qu'une première lumière (122) avec une première ouverture distale (126) disposée à son extrémité distale, et une deuxième lumière (124) reliée à la première lumière mais s'étendant à distance au-delà de celle-ci vers une deuxième ouverture distale (130). Selon l'invention, un protecteur (120) est ajouté à la deuxième lumière (124) distalement par rapport à la première ouverture distale (126) et s'étend radialement et d'une manière proximale par rapport à un bord proximal libre (134) pour se mettre en prise radialement avec les parois de vaisseau autour de la première ouverture distale afin de centrer le cathéter (102) à l'intérieur du vaisseau pour empêcher l'occlusion de la première ouverture distale (126). De plus, une pluralité d'ouvertures (136) traverse le protecteur (120) pour permettre au sang de circuler à travers celui-ci.
