Suturing devices and methods for suturing an anatomic valve
First Claim
1. A method for suturing an anatomic valve, the method comprising:
- delivering an elongate body having a proximal end and a distal end at least partially through an anatomic valve;
moving a first arm attached to the elongate body near the distal end of the elongate body from a retracted position to an extended position, the first arm comprising a first suture mount configured to releasably retain a first suture portion;
advancing a first suture catch mechanism operatively coupled to the elongate body from a retracted position to an advanced position, wherein the advancing delivers the first suture catch mechanism through a first portion of tissue of the anatomic valve to interact with the first suture portion in the first suture mount;
retracting the first suture catch mechanism from the advanced position to the retracted position to retrieve the first suture portion through the first portion of tissue;
moving a second arm attached to the elongate body near the distal end of the elongate body from a retracted position to an extended position, the second arm comprising a second suture mount configured to releasably retain a second suture portion;
advancing a second suture catch mechanism operatively coupled to the elongate body from a retracted position to an advanced position sequentially after the advancing of the first suture catch mechanism, wherein the advancing delivers the second suture catch mechanism through a second portion of tissue of the anatomic valve to interact with the second suture portion in the second suture mount;
retracting the second suture catch mechanism from the advanced position to the retracted position to retrieve the second suture portion through the second portion of tissue; and
removing the distal end of the elongate body from the anatomic valve.

Abstract
A device for suturing an anatomic valve can comprise 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 comprise 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.
