1. A surgical suturing instrument comprising:
- (a) an elongated shaft;
(b) a tissue engaging gap formed proximal to an end of the shaft;
(c) a needle reciprocally movable across the gap from a proximal end of the gap to a distal end of the gap;
(d) the needle having a ferrule engaging tip(e) a ferrule receiving aperture at a distal end of the gap an element cooperating with the aperture sequentially holding and releasing the ferrule so that in a first mode, the needle engages the ferrule and draws a suture across the gap, and in a second mode, the ferrule is retained in the aperture and the needle separates from the ferrule and is retracted across the gap leaving the ferrule in the aperture.

Abstract
An instrument and method for suturing wound closures is provided having a handle, shaft and suture engagement mechanism. The instrument provides for multiple placements or “bites” of suture in tissues to enable a wide variety of suturing techniques, including the ability to “run” a suture. The instrument further facilitates suture knot tying. The method of this instrument provides for rapid and effective remote suture placement and knot tying.

22. A surgical suturing instrument for placing multiple suture loops comprising:
-
(a) an elongated shaft; (b) a reciprocating suture pickup member mounted on said shaft; (c) a suture holder engaged by said reciprocating suture pick up member the suture holder having an element sequentially coupling a suture to the pick up member for drawing the suture through a first tissue section and releasing the suture from the pick up member for repeated coupling and drawing the suture through a second tissue section spaced from the first tissue section. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31)

32. A surgical suturing instrument comprising:
-
(a) a reciprocating tissue penetrating member; (b) a suture holder; (c) means for alternately coupling the reciprocating tissue penetrating member to the suture holder for drawing a length of suture through a tissue section and releasing the reciprocating tissue penetrating member from the suture holder. - View Dependent Claims (33, 34, 35, 36)

37. A method of closing a wound with a stitch at a remote surgical site comprising:
-
(a) disposing a suture on one side of a section of tissue proximal to the wound; (b) passing a needle through the section of tissue proximal to the wound; (c) capturing the suture with the needle; (d) drawing the suture through the section of tissue; (e) releasing the suture from the needle; and (f) repeating steps b–
e without drawing the suture from the remote surgical site. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45)
