Abstract: The implant (12) according to the invention comprises a tubular frame (16), a plurality of distal arms (18) capable of pressing on a first face of a tissue, and a plurality of proximal arms (20) having an end (62) connected to the frame and a free end (64) intended to press on a second face of the tissue to clamp the tissue. The implant comprises a first integral assembly including a first part (38) of the frame and the proximal arms (20), and a second integral assembly including a second part of the frame (40) and the distal arms (18), the first assembly and the second assembly being attached one on top of the other. The first part (38) of the frame is in the form of a proximal sleeve, extending longitudinally between a proximal end (41) and a distal end (43) of the sleeve. The connected end (62) of each proximal arm (20) is connected to the distal end (43) of the proximal sleeve (38), and the free end (64) of each proximal arm (20) extends beyond that distal end (43) of the proximal sleeve (38).

Abstract: The implant comprises a tubular proximal sleeve, extending between a proximal end and a distal end, and deployable between a contracted configuration and a deployed configuration. Proximal arms each extend between an end connected to the distal end, and a free end positioned past the distal end. At least one proximal arm is elastically deformable between a separating position and an anchoring position, the radial distance between its free end and its connected end being larger in the separating position rather than in the anchoring position. This proximal arm is elastically recalled toward its anchoring position. The implant includes: a first stop, supported by this proximal arm, and a second stop, cooperating with the first stop in the contracted configuration to keep this proximal arm in its separating position, and releasing this first stop in the deployed configuration.
