AUTOMATED INSERTION DEVICE FOR HEART VALVE PROSTHESIS
First Claim
1. Automated ancillary device for inserting and fixing by means of clips an annular body, namely a prosthetic cardiac valve, on a substantially annular resilient volume including an opening, said ancillary device including, coaxially fitted about a longitudinal axis, means for receiving and supporting (8) said annular body designed capable of receiving the latter coaxially to its axis of rotation, means for radially unfolding about said longitudinal axis articulated clip supports designed capable of bearing clips, which are designed capable of passing through both a thickness of material belonging to such an annular volume and a thickness of material belonging to said annular body under the action of longitudinal pushing means of said clip supports with respect to said means for receiving and supporting, wherein it also includes means for gripping material of said annular volume designed capable of radially retracting said material, and wherein said means for radially unfolding about said longitudinal axis said articulated clip supports are designed capable of moving said clips parallel to said longitudinal axis.

Abstract
The invention concerns an automated ancillary device (100) for inserting and fixing by means of clips an annular body (200), namely a prosthesis, on a annular resilient volume (23) including, coaxial about an axis (D), means for receiving and supporting (8) said body (200) coaxial to its axis, means for radially unfolding (500) about said axis (D) articulated supports (4) capable of bearing clips (21), the latter being capable of passing through both a thickness of material belonging to such a volume (23) and a thickness of material belonging to said body (200), under the action of means for longitudinally pushing (600) said supports (4) with respect to said means for receiving and supporting (8).
It includes means for gripping (300) material of the volume (23) capable of radially retracting said material. The means for radially unfolding (500) are capable of moving said clips (21) parallel to said axis (D).
