PROBLEM TO BE SOLVED: To provide a suturing device and method for suturing a cardiac valve such as a mitral valve, aortic valve, tricuspid valve, or pulmonary valve.SOLUTION: A device 100 has an elongate body, a suture catch mechanism 106, and a suture clasp arm 104. The suture catch mechanism is operatively coupled to the elongate body for movement between a retracted position and an advanced position, and the suture clasp arm is operatively attached to the elongate body for movement between a retracted position and an extended position. The suture clasp arm has a suture clasp 126 configured to releasably retain a suture portion 130. While the suture clasp arm is at least partially retracted, the suture clasp is positioned on the suture clasp arm such that the suture catch mechanism retrieves the suture portion from the suture clasp arm, and the suture clasp arm is closed about a tissue portion without damaging the tissue portion. |
