1. An anchor device (1, 100) configured to cooperate with a heart valve prosthesis to be implanted at a patient's valve annulus, said device comprising:
a leakproof toroidal element (2, 200) that is compressible and expandable, comprising an external periphery and a surface defining a hole; and an anchor element (3, 300) presenting a compressible and expandable mesh structure comprising a ventricular collar (33, 303) and an auricular collar (31, 301) connected together by a tubular portion (32, 302); said toroidal element (2, 200) surrounding said tubular portion (32, 302) of said anchor element (3, 300) and said anchor element being intended to encircle said heart valve prosthesis; wherein said toroidal element (2, 200) presents, over at least a portion of its external periphery, a zone of weakness (24, 204) against radial compression when in situation and said toroidal element (2, 200) presents, over at least a portion of the surface defining its hole, a zone (23, 203) of increased resistance to radial compression when in situation. |
