Title
(EN) VENOUS RETURN CATHETER WITH ANCHOR MEANS AND METHOD FOR USE
(FR) CATHETER DE RETOUR VEINEUX DOTE D'UN SYSTEME D'ACCROCHAGE ET SON PROCEDE D'UTILISATION
Abstract
(EN)
This invention is a two stage venous catheter (20) which removably anchors a retrograde cardioplegia catheter (42) in place within the coronary sinus of a patient. A suture loop (32) extends therefrom in the region of the right atrium near the coronary sinus. The suture loop (32) is tightened around a retrograde cardioplegia catheter (42), and thus helps prevent inadvertent dislodgement of the cardioplegia catheter (42) from the coronary sinus. The cardioplegia catheter (42) which is to be anchored in place by the suture loop (32) includes a balloon (48) positioned within the coronary sinus which blocks the coronary ostium. Alternatively, an elongated balloon (148) which substantially blocks the coronary veins emptying near the coronary ostium, is utilized.
(FR)
La présente invention porte sur un cathéter (20) veineux à deux phases qui se fixe de manière détachable sur un cathéter (42) de cardioplégie rétrograde situé dans le sinus coronaire d'un patient. Une boucle (32) de suture s'étend depuis ce point dans la région de l'oreillette droite au voisinage du sinus coronaire. La boucle (32) de suture est serrée autour d'un cathéter (42) de cardioplégie rétrograde et empêche ainsi le cathéter (42) de cardioplégie de se déplacer et de sortir par inadvertance du sinus coronaire. Le cathéter (42) de cardioplégie devant être fixé par la boucle (32) de suture comprend un ballonnet (48) placé à l'intérieur du sinus coronaire qui bloque l'ostium coronaire. Dans une autre forme de réalisation on utilise un ballonnet allongé (148) qui bloque sensiblement les veines coronaires débouchant à proximité de l'ostium coronaire.
