Suturing devices and methods for suturing an anatomic valve
First Claim
1. A device for suturing an anatomic valve, comprising:
- an elongate body;
an arm having a distal end attached by a fixed pivot to a distal end of the elongate body for pivoting movement between a retracted arm position and an extended arm position;
a recess defined between the elongate body and the arm when the arm is fully retracted, the recess being sized and shaped to receive a leaflet of a valve between the elongate body and the arm without damaging the leaflet;
a needle having tissue-piercing portion, the needle being operatively coupled to the elongate body for reversible movement betweena) a retracted needle position wherein the tissue-piercing portion is disposed adjacent a proximal end of the recess andb) an advanced needle position wherein the tissue-piercing portion spans the recess to be received by the arm; and
wherein the arm comprises a suture clasp configured to releasably retain a suture portion, the suture clasp being positioned on a proximal end of the arm such that, when the arm is in the retracted arm position, the needle is adapted to retrieve the suture portion retained in the suture clasp by moving from the retracted needle position to the advanced position, retrieving the suture portion in the advanced position, and returning to the retracted needle position.

Abstract
A device for suturing an anatomic valve has an elongate body, a suture catch mechanism and a suture clasp arm. The suture catch mechanism is operatively coupled to the elongate body for movement between a retracted position and an advanced position. The suture clasp arm is pivotally attached to the elongate body for movement between a retracted position and an extended position. The suture clasp arm has 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.

7. A method of suturing an anatomic valve, comprising:
-
positioning a suturing device at least partially within an anatomic valve, wherein the suturing device comprises an elongate body and a first arm having a distal end attached by a fixed pivot to a distal end of the elongate body, deploying the first arm about the pivot from a retracted arm position to an extended arm position, the first arm comprising a suture clasp for releasably holding a first suture portion; fully retracting the first atm to define a recess between the elongate body and the arm, the recess receiving a first leaflet of the anatomic valve without damaging the leaflet; while the first arm is fully retracted about the first leaflet, advancing a first needle from a retracted needle position wherein a tissue-piercing needle portion is disposed adjacent a proximal end of the recess through the first leaflet to an advanced needle position wherein the tissue-piercing portion spans the recess to be received by the arm engaging 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 (8, 9, 10, 11)
