Title
(EN) ASPIRATION CATHETER
(FR) CATHETER D'ASPIRATION
Abstract
(EN)
A catheter comprising an elongated shaft having a first lumen extending from a proximal shaft section to the distal end of the shaft with a distal port at the shaft distal end, and a second lumen extending in at least a distal shaft section from a proximal port to a distal port located proximal to the distal port of the first lumen. In a one embodiment, the catheter is an aspiration catheter with a vacuum source in fluid communication with the first lumen, providing improved removal of embolic debris from within a body lumen. The first lumen can alternatively be connected to a source of fluid, so that the catheter is a fluid delivery catheter such as perfusion or drug delivery catheters.
(FR)
L'invention concerne un cathéter muni d'une tige allongée ayant une première lumière qui s'étend entre une section de tige proximale et l'extrémité distale de la tige, laquelle comprend un orifice distal, et une seconde lumière qui s'étend, dans au moins une section de tige distale, entre un orifice proximal et un orifice distal situé à proximité de l'orifice distal de la première lumière. Dans un mode de réalisation, le cathéter est un cathéter d'aspiration qui comprend une source de vide en communication fluidique avec la première lumière, ce qui améliore l'extraction de débris emboliques de l'intérieur d'une lumière corporelle. La première lumière peut être raccordée en alternance avec une source de fluide, de façon à transformer le cathéter en un cathéter de distribution de liquides, tel qu'un cathéter de perfusion ou d'administration de médicaments.
