IMPLANT FOR TREATING A BIOLOGICAL VALVE
First Claim
Patent Images
1. An implant for treating a biological valve, intended to be positioned in a blood flow passage delimited by the valve, and including:
- a proximal sleeve, deployable between a retracted configuration and a deployed configuration, the proximal sleeve comprising a proximal tubular body and a plurality of proximal arms, each extending between a first end connected to the proximal tubular body, and a second free end intended to bear on a first face of a leaflet of the valve or on an annulus of the valve, anda distal sleeve, deployable between a retracted configuration and a deployed configuration, intended to be assembled with the proximal sleeve to form a tubular armature when the proximal sleeve and the distal sleeve are assembled, each in the deployed configuration, the distal sleeve comprising a distal tubular body and a plurality of distal arms intended to bear on a second face of the valve leaflet and/or the annulus such that the valve leaflet and/or the annulus are pinched between the proximal arms and the distal arms,wherein each proximal arm protrudes radially away from the proximal tubular body and defines a receiving space for the valve leaflet, delimited by the proximal arm, with no participation of the tubular armature when the proximal sleeve and the distal sleeve are assembled.

Abstract
This implant (12) for treating a valve is intended to be positioned in a blood flow passage, and includes:
- a proximal sleeve (14) comprising proximal arms (32), intended to bear on a first face of a leaflet (18) or on an annulus (17) of the valve, and
- a distal sleeve (16), intended to be assembled with the proximal sleeve (26) to form a tubular armature (24), and comprising distal arms (36) intended to bear on a second face of the valve leaflet (18) and/or the annulus (17).
Each proximal arm (32) protrudes radially away from the proximal tubular body (30A) and defines a receiving space (18) for the leaflet (18), delimited by the proximal arm (32), with no participation of the tubular armature (24) when the proximal sleeve (26) and the distal sleeve (28) are assembled.
