REPLACEMENT HEART VALVE IMPLANT WITH INVERTIBLE LEAFLETS
First Claim
1. A locking mechanism for a medical implant, comprising:
- a buckle member;
a post member axially translatable with respect to the buckle member, the post member including a receiving portion proximate a proximal end of the post member, a distal end, a laterally-arched central body portion extending between the receiving portion and the distal end, and a cantilevered leg extending proximally from the distal end; and
an actuator element including a proximal shaft portion and a distal engagement portion, the distal engagement portion being configured to releasably engage the receiving portion of the post member;
wherein the proximal shaft portion is pivotable with respect to the distal engagement portion.

Abstract
A locking mechanism for a medical implant may include a buckle member, a post member axially translatable with respect to the buckle member, the post member including a receiving portion proximate a proximal end of the post member, a distal end, a laterally-arched central body portion extending between the receiving portion and the distal end, and a cantilevered leg extending proximally from the distal end, and an actuator element including a proximal shaft portion and a distal engagement portion, the distal engagement portion being configured to releasably engage the receiving portion of the post member. The proximal shaft portion may be pivotable with respect to the distal engagement portion.

13. A replacement heart valve implant, comprising:
-
a tubular anchor member defining a central longitudinal axis; a plurality of locking mechanisms, each locking mechanism comprising; a buckle member fixedly attached to the tubular anchor member; and a post member axially translatable with respect to the buckle member, the post member including a receiving portion proximate a proximal end of the post member, a distal end, a laterally-arched central body portion extending between the receiving portion and the distal end, and a cantilevered leg extending proximally from the distal end; a plurality of valve leaflets, wherein each valve leaflet is coupled to the cantilevered leg of at least one of the plurality of locking mechanisms; and a plurality of actuator elements corresponding to the plurality of locking mechanisms, each actuator element including a proximal shaft portion and a distal engagement portion, wherein the proximal shaft portion is pivotable relative to the distal engagement portion, wherein the distal engagement portion is releasably fixed to the receiving portion of one post member. - View Dependent Claims (14, 15, 16, 17)

18. A replacement heart valve implant, comprising:
-
a tubular anchor member defining a central longitudinal axis, the tubular anchor member being configured to shift between a delivery configuration and a deployed configuration; a plurality of locking mechanisms, each locking mechanism comprising; a buckle member fixedly attached to the tubular anchor member; and a post member axially translatable with respect to the buckle member, the post member including a receiving portion proximate a proximal end of the post member, a distal end, a laterally-arched central body portion extending from the receiving portion to the distal end, and a cantilevered leg extending proximally from the distal end; a plurality of valve leaflets, wherein each valve leaflet is coupled to the cantilevered leg of at least one of the plurality of locking mechanisms, and a plurality of actuator elements corresponding to the plurality of locking mechanisms, each actuator element including a proximal shaft portion pivotably connected to a distal engagement portion, the distal engagement portion being releasably fixed to the receiving portion of one post member, wherein the distal engagement portion is configured to pivot with respect to the proximal shaft portion in a radial direction relative to the central longitudinal axis. - View Dependent Claims (19, 20)
