Abstract: A device (100) for suturing an anatomic valve can comprise an elongate body (142), a suture catch mechanism (106), and a suture clasp arm (104). The suture catch mechanism (106) can be operatively coupled to the elongate body (142) for movement between a retracted position and an advanced position. The suture clasp arm (104) can be attached to the elongate body (142) for movement between a retracted position and an extended position. The suture clasp arm (104) can comprise a suture clasp (126) configured to releasably retain a suture portion (130). In some embodiments, the suture clasp (126) is positioned on the suture clasp arm (104) such that the suture catch mechanism (106) retrieves the suture portion (130) from the suture clasp arm (104) while the arm (104) is at least partially retracted. In some embodiments, the suture clasp arm (104) can be closed about a tissue portion without damaging the tissue portion.
