CA 2652381

The present invention provides a balloon cuff (20) comprising an attachment structure adapted to be disposed around an exterior surface of an endoscope, and a balloon (30) coupled to the attachment structure. An inflation means (40) is in fluid communication with the balloon. The balloon has a deflated state suitable for insertion into a body passage and an inflated state suitable for urging stone fragments along the body passage. Optionally, an intraductal shock wave lithotripsy procedure may be performed through the working lumen of the first endoscope (50) while the balloon cuff is disposed, either inflated or deflated, about the exterior surface of the first endoscope. The first endoscope and balloon cuff may be used alone to remove stone fragments, or alternatively, may be used in conjunction with a second endoscope, such as a duodenoscope, having a working lumen sized to received the first endoscope having the balloon cuff disposed thereon.

La présente invention concerne un coussinet ballon qui comprend une structure de fixation pour être disposée autour d'une surface externe d'un endoscope et un ballon couplé à la structure de fixation. Un moyen de gonflement est en communication fluide avec le ballon. Le ballon peut adopté un état dégonflé propre à l'insertion dans un passage du corps et un état gonflé propre à repousser des fragments de calcul le long du passage du corps. Une procédure de lithotripsie à onde de choc intraductale peut éventuellement être réalisée par la lumière active du premier endoscope pendant que le coussinet ballon est disposé, gonflé ou dégonflé, autour de la surface externe du premier endoscope. Le premier endoscope et le coussinet ballon peuvent être utilisés seuls pour retirer des fragments de calcul, ou conjointement avec un deuxième endoscope, tel qu'un duodénoscope, ayant une lumière active de taille à recevoir le premier endoscope où se trouve disposé le coussinet ballon.
