Abstract: In certain embodiments, a multiple component heart valve prosthesis includes an abutment ring and a removable bioprosthetic heart valve. The abutment ring is configured for attachment at a heart valve annulus location and includes a locking system. The removable bioprosthetic heart valve includes a valve frame and at least one locking feature. The at least one locking feature is configured to be received by the locking system. The bioprosthetic heart valve can be rotated relative to the abutment ring such that the at least one locking feature transitions from a disengaged position to a first engaged position. When in the disengaged position the bioprosthetic heart valve may be removed from the abutment ring, and when rotated to the engaged position the bioprosthetic heart valve is restrained from axial movement relative to the abutment ring.

Abstract: An implant device (V), such as a heart valve, for implantation in an animal body includes an annular structure and one or more elongated anchoring members deployable to a deployed condition for insertion into an animal body. The anchoring members are retractable from the deployed condition to a rolled up condition wherein the anchoring members protrude radially out from the annular structure of the device (V) to provide anchoring to a body structure (AS) of an animal. In the rolled up condition the anchoring members at least partly protrude axially of the annular structure of the device (V).
