Title (EN) DILATATION CATHETER WITH EXPANDING BALLOON
(FR) CATHETER DE DILATATION A BALLON EXPANSIBLE
Abstract:
(EN) A dilatation catheter is provided with an expanding balloon which can be made to advance into a narrowed coronary artery along a guide wire (10) placed by a guide catheter. An inflation tube (11) is provided for expanding the balloon, which consists of a hose-like outer envelope (1) to which is connected, at the axially oriented edges (4, 5), an inner envelope (2) also having a hose-like shape. Between the inner envelope (2) and the outer envelope (1) is an inner annular space (3) which surrounds an open central lumen (9) extending axially through the balloon and ensures during dilatation a constant flow of blood into the coronary artery.
(FR) Un cathéter de dilatation possède un ballon expansible que l'on peut faire avancer dans une artère coronaire rétrécie le long d'un fil de guidage (10) mis en place par un cathéter de guidage. Un tube de gonflage (11) est prévu pour l'expansion du ballon. Ce dernier est constitué d'une enveloppe extérieure (1) en forme de boyau, à laquelle est reliée, au niveau des bords (4, 5) orientés en sens axial, une enveloppe intérieure (2) également en forme de boyau. Entre l'enveloppe intérieure (2) et l'enveloppe extérieure (1) du ballon se trouve un espace interne (3) annulaire qui entoure un orifice central ouvert (9) s'étendant en sens axial à travers le ballon qui permet de maintenir, pendant la dilatation, un flux sanguin dans l'artère coronaire.
