Title
(EN) INFUSION SLEEVE CATHETER HAVING DISTAL DISTRIBUTION MANIFOLD
(FR) SONDE A MANCHON DE PERFUSION POSSEDANT UN COLLECTEUR DE DISTRIBUTION DISTAL
Abstract
(EN)
An infusion catheter (10) for use in combination with a balloon catheter comprises a shaft and a radially expansible infusion sleeve (12) attached to a distal end of the shaft. A manifold structure (14) connects a lumen within the shaft (16) to a plurality of lumens formed over the infusion sleeve (12). A balloon entry port (56) is provided at a proximal end of the infusion sleeve (12) to receive the balloon (B) of the balloon catheter (BC). The infusion catheter (10) and balloon catheter (BC) are introduced to a target location within a body lumen, typically a target site within a coronary artery, simultaneously. After use of the balloon catheter (BC) to treat the body lumen in a conventional manner, the expansible sleeve of the infusion catheter (10) may be advanced over the balloon (B), which is then inflated. An infuser is delivered through a delivery lumen in the shaft (16) to a plurality of infusion lumens (26) on the radially expanded sleeve while the balloon (B) remains inflated with the infuser exiting drug deliveryports (28) near the distal ends of the infusion lumens (26).
(FR)
Sonde de perfusion (10) utilisable en association avec une sonde à ballonnet, et comportant une tige et un manchon de perfusion (12) expansible dans le sens radial et fixé à une extrémité distale de la tige. Une structure formant collecteur (14) relie une lumière intérieure de la tige (16) à plusieurs lumières formées sur le manchon de perfusion (12). Un orifice (56) d'introduction du ballonnet est prévu à l'extrémité proximale du manchon de perfusion (12) pour recevoir le ballonnet (B) de la sonde à ballonnet (BC). On place simultanément la sonde de perfusion (10) et la sonde à ballonnet (BC) au niveau d'un site cible à l'intérieur d'une lumière corporelle, en général à l'intérieur d'une artère coronaire. Après l'utilisation de la sonde à ballonnet (BC) pour un traitement classique de la lumière corporelle, on peut faire avancer le manchon expansible de la sonde de perfusion (10) par-dessus le ballonnet (B), puis gonfler ce dernier. On fait passer une solution intraveineuse dans une lumière d'administration ménagée dans la tige (16) pour la faire parvenir à plusieurs lumières de perfusion (26) sur le manchon agrandi radialement, pendant que le ballonnet (B) demeure à l'état gonflé et que la solution sort des orifices (28) d'administration de médicament situés à proximité des extrémités distales des lumières de perfusion (26).
