Abstract
An exemplary valve repair device is released from tissue of a valve of a patient by applying tension to a movable arm of a clasp in a retraction direction. A fixed arm of the clasp is attached to an inner paddle portion of a paddle of the valve repair device. The inner paddle portion is connected to an outer paddle portion of the paddle of the valve repair device. Pulling the moveable arm of the clasp flexes the inner paddle portion to allow the moveable arm to move in the retraction direction and thereby release the clasp from the valve tissue.
