Suturing devices and methods for suturing an anatomic valve
First Claim
1. A device for suturing a heart valve, comprising:
- an elongate body having a proximal end and a distal end configured to be delivered through a heart valve;
a first needle operatively coupled to the elongate body near the distal end of the elongate body and configured to move between a retracted position and an advanced position; and
a first arm attached to the elongate body near the distal end of the elongate body and disposed proximal to the first needle when the first needle is in the retracted position and the device is in a linear configuration, the first arm being configured to move between a retracted position and an extended position, the first arm comprising a suture mount configured to releasably retain a suture portion, the first arm in its extended position configured to position a leaflet of the valve between the first arm and the distal end of the elongate body;
wherein the first needle is configured to move proximally from its retracted position to its advanced position to penetrate the valve leaflet and engage the suture portion retained in the suture mount when the first arm is in its extended position, and wherein the first needle with the engaged suture portion is configured to be retracted through the valve leaflet when the first needle is returned to its retracted position.

Abstract
A device for suturing an anatomic valve, the device having an elongate body, a suture catch mechanism and a suture clasp arm. The suture catch mechanism can be operatively coupled to the elongate body for movement between a retracted position and an advanced position. The suture clasp arm can be attached to the elongate body for movement between a retracted position and an extended position. The suture clasp arm can have a suture clasp configured to releasably retain a suture portion. In some embodiments, 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 while the arm is at least partially retracted. In some embodiments, the suture clasp arm can be closed about a tissue portion without damaging the tissue portion.
