AUTOMATED ANCILLARY DEVICE FOR INSERTING AND FIXING AN ANNULAR BODY BY MEANS OF CLIPS

摘要

Automated ancillary device (1) for inserting and fixing by means of clips (6) an annular body, namely a prosthetic heart valve (42), on a substantially annular resilient volume, including an opening, including, coaxially fitted about a longitudinal axis, means for receiving and supporting said annular body designed capable of receiving the latter coaxially to its axis of rotation. It includes, on the one hand, means for longitudinally pushing about said longitudinal axis, which consist of means for pushing by percussion under the action of springy restoring means, and, on the other hand, clip- supporting means designed capable of bearing clips made out of shape-memory material, of nitinol or the like, said clips including two legs connected by a heel, and designed so that at least one of said legs passes through both a thickness of a material belonging to said annular body and a thickness of a material belonging to said substantially annular resilient volume, under the action of said longitudinal pushing means.
