Title
(EN) BLOOD VESSEL OCCLUSION TROCAR HAVING SIZE AND SHAPE VARYING INSERTION BODY
(FR) TROCART POUR OCCLUSION DE VAISSEAU SANGUIN AYANT UN CORPS D'INSERTION DONT LA DIMENSION ET LA FORME SONT VARIABLES
Abstract
(EN) An occluder apparatus (10) for obstructing the flow of blood in a blood vessel has an elongated hollow tubular body (12) having a leading end sized for reception in the blood vessel and includes a portion of the body fabricated from a material soluble in blood, and a piercing device for inserting the body through the wall of the blood vessel to extend the leading end into the interior of the blood vessel. An inflatable diaphragm (54) is carried by the body in a collapsed, deflated condition, and the apparatus includes a passage for conducting an inflating fluid from an external source, which is into fluid communication with the interior of the diaphragm, to effect expansion of the diaphragm. Elongated openings (53, 55, 57) in the body enable the diaphragm to be released in an inflated state from the body into flexible occluding engagement with the interior wall of the blood vessel about the full circumference of a transverse section thereof.
(FR) Un appareil d'occlusion utilisé pour obstruer l'écoulement du sang dans un vaisseau sanguin comprend un corps tubulaire creux allongé présentant une extrémité avant dimensionnée pour se loger dans le vaisseau sanguin et comprend une partie du corps qui est réalisée dans un matériau soluble dans le sang ainsi qu'un dispositif de percement qui permet d'introduire le corps dans la paroi du vaisseau sanguin pour que l'extrémité avant pénètre à l'intérieur du vaisseau sanguin. Un diaphragme gonflable est supporté par le corps dans un état aplati et dégonflé, et l'appareil comprend un passage d'amenée pour un fluide de gonflage provenant d'une source extérieure, qui est en communication par le fluide avec l'intérieur du diaphragme, afin d'assurer la dilatation du diaphragme. Des ouvertures allongées formées dans le corps permettent de sortir dudit corps, le diaphragme à l'état gonflé pour assurer une obstruction souple avec la paroi intérieure du vaisseau sanguin tout autour de la circonférence d'une section transversale de ce dernier.
