Abstract
A mitral valve clip includes a stud, a lock, and two arms. The stud includes a shank, and the lock includes a frame relative to which the stud is translatable and into which the shank extends. The lock is able to prevent movement of the stud relative to the lock in at least one direction by locking engagement of the shank. The two arms are connected to the lock and the stud such that an angle between the arms depends on a location of the stud relative to the lock. The locking engagement of the shank that prevents movement of the stud relative to the lock in the at least one direction is only possible when the angle between the arms is below a predefined locking threshold.
Claims20
A mitral valve clip, comprising:
- a stud including a shank;
- a lock including a frame relative to which the stud is translatable and into which the shank extends, the lock being able to prevent movement of the stud relative to the lock in at least one direction along an axis by locking engagement of the shank;
- two arms connected to the lock and the stud such that an angle between the arms depends on a location of the stud relative to the lock;
- wherein the locking engagement of the shank that prevents movement of the stud relative to the lock in the at least one direction is only possible when the angle between the arms is equal to or below 95°.
An assembly comprising:
- a stud including a shank, the shank having a rough-textured portion and a smooth portion aligned radially about a longitudinal axis of the shank with the rough-textured portion;
- a lock comprising:
- a frame into which the shank extends along the longitudinal axis;
- and
- a grip biased relative to the frame toward the longitudinal axis such that movement of the stud relative to the grip in at least one direction is prevented when the grip contacts the rough-textured portion of the shank, but movement of the stud relative to the grip is not prevented by the grip when the grip contacts only the smooth portion of the shank.
