Heart valve sealing devices and delivery devices therefor

Abstract:

An exemplary valve repair device for repairing a valve of a patient has a paddle, and a clasp. The clasp has a fixed arm attached to the paddle and a moveable arm. The moveable arm includes barbs that are spaced apart from a connection between the moveable arm and the fixed arm. The moveable arm is movable between open and closed positions relative to the fixed arm. The moveable arm has a weakened portion between the barbs and the connection between the moveable arm and the fixed arm. Applying tension to the movable arm in a retraction direction stretches the moveable arm and moves the barbs in the retraction direction.
