Title (EN) SUTURELESS ANCHORING DEVICE FOR HEART PUMP
(FR) DISPOSITIF D'ANCRAGE SANS SUTURE D'UNE POMPE CARDIAQUE
Abstract:
(EN) The invention concerns a device for sutureless attachment to an opening of a ventricular wall, comprising: - a hollow main body having an outer surface (11), - a ring (15) received at a first end of the hollow body, said ring (15) being able to move along at least part of the outer surface (11) of the hollow body, - a tubular membrane (16) covering the outer surface (11) of the hollow body, extending between said ring (15) and the second end of the hollow body, - a distal end (17) of said tubular membrane (16), positioned at the second end side, being self-expandable between a first configuration in which it has a tubular shape, and a second configuration in which it defines a first flange (18) extending radially from the hollow body, - the other end of this tubular membrane (16) being able to be deformed by the movement of said ring (15) in such a way as to form a retaining flange (20), the position of which can vary relative to said first flange (18) so as to adapt to ventricular walls of different thicknesses, - said retaining flange (20) being intended to come into contact with the opposing face of said ventricular wall such that said flanges and the assembly formed by the part of the hollow body and the portion of the tubular membrane (16) covering it, passing through said ventricular wall via said opening, immobilise said attachment device in said opening.
(FR) L'invention concerne un dispositif de fixation sans suture sur une ouverture d'une paroi ventriculaire, comprenant : - un corps principal creux présentant une surface (11) externe, - une bague (15) reçue à une première extrémité du corps creux, cette bague (15) étant mobile le long d'au moins une partie de la surface (11) externe du corps creux, - une membrane (16) tubulaire recouvrant la surface (11) externe du corps creux en s'étendant entre ladite bague (15) et la seconde extrémité du corps creux, - une extrémité (17) distale de cette membrane (16) tubulaire, placée du côté de cette seconde extrémité, étant auto-expansible entre une première configuration dans laquelle elle présente une forme tubulaire, et une seconde configuration dans laquelle elle définit une première (18) bride s'étendant radialement à partir du corps creux, - l'autre extrémité de cette membrane (16) tubulaire étant susceptible d'être déformée par le déplacement de ladite bague (15) de sorte à former une bride (20) de retenue dont la position peut varier par rapport à ladite première (18) bride de manière à s'adapter à des parois ventriculaires d'épaisseurs différentes, - ladite bride (20) de retenue étant destinée à venir en contact avec la face opposée de ladite paroi ventriculaire de sorte que lesdites brides et l'ensemble formé par la partie du corps creux et la portion de la membrane (16) tubulaire la recouvrant, traversant ladite paroi ventriculaire au travers de ladite ouverture, bloquent en position ledit dispositif de fixation dans ladite ouverture.
