Implant device and implantation kit
First Claim
1. An implant device for implantation in an animal body, the device including an annular structure extending axially between opposed ends and at least one elongated anchoring member deployable to a deployed condition for insertion into an animal body and retractable from said deployed condition to a rolled up condition wherein the anchoring member protrudes radially outwardly of the annular structure of the device to provide anchoring of the implant device to a body structure of an animal, wherein in said rolled up condition the anchoring member at least partly protrudes axially outwardly of the annular structure of the device, and wherein winding of the at least one elongated anchoring member from the deployed condition to the rolled up condition is with a winding trajectory having an angular extent between 180°
- and 900°

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).

20. An implantation kit for an implant device including:
-
an implant device for implantation in an animal body, the device including an annular structure extending axially between opposed ends and at least one elongated anchoring member deployable to a deployed condition for insertion into an animal body and retractable from said deployed condition to a rolled up condition wherein the anchoring member protrudes radially outwardly of the annular structure of the device to provide anchoring of the implant device to a body structure of an animal, wherein in said rolled up condition the anchoring member at least partly protrudes axially outwardly of the annular structure of the device; and at least one constraint member to cooperate with the at least one anchoring member to constrain the at least one anchoring member to the deployed condition during insertion into an animal body and to permit winding of the at least one anchoring member to a rolled up condition to provide anchoring of the implant device to a body structure of an animal, wherein the at least one anchoring member is tubular with a longitudinal cavity and the at least one constraint member includes a wire member for insertion into the longitudinal cavity of the at least one anchoring member to maintain the at least one anchoring member in the deployed condition, the wire member extractable from the longitudinal cavity of the at least one anchoring member to permit winding thereof to the rolled up condition.
