SUTURING DEVICES AND METHODS FOR SUTURING AN ANATOMIC VALVE
First Claim
1. A device for suturing an anatomic valve, comprising:
- an elongate body;
a needle operatively coupled to the elongate body for movement between a retracted position and an advanced position;
an arm attached to the elongate body near a distal end of the elongate body for movement between a retracted position and an extended position, the arm comprising a suture mount configured to releasably retain a suture portion, the suture mount being positioned on the arm such that the needle retrieves the suture portion retained in the suture mount when the needle is moved from the retracted position to the advanced position and returned to the retracted position; and
a recess positioned between the elongate body and the arm, the recess being sized and shaped to receive a leaflet of a valve between the elongate body and the arm without damaging the leaflet.

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.

12. A method of suturing an anatomic valve, comprising:
-
positioning a suturing device comprising an elongate body at least partially within an anatomic valve; deploying a first arm from the elongate body, the first arm releasably holding a first suture portion; at least partially closing the first arm about a first leaflet of the anatomic valve; while the first arm is at least partially closed about the first leaflet, advancing a first needle through the first leaflet to engage the first suture portion; drawing the first suture portion through the first leaflet; passing a second suture portion through a second leaflet; and securing together the first and second suture portions. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. A method of suturing a heart valve, comprising:
-
advancing a first elongate member to a heart valve; extending a first arm from the elongate member around a first heart valve portion, the first arm releasably holding a first suture portion; advancing a first needle from the elongate member through a first heart valve portion to retrieve a first suture portion from the first arm; extending a second arm around a second heart valve portion, the second arm releasably holding a second suture portion; advancing a second needle through a second heart valve portion to retrieve the second suture portion from the second arm; and securing the first and second suture portions. - View Dependent Claims (22, 23, 24)
