1. A suturing device for deploying a length of suture, the suturing device comprising:
- a housing having a distal portion which is engageable with the length of suture;
a tissue receiving recess disposed proximally of the distal portion;
at least a first and a second needle, each having a tissue piercing end and a proximal end, each of the needles being axially movable distally and proximally across the tissue receiving recess; and
a selecting member located within the housing, the selecting member being rotatable and having an engagement surface that is axially moveable;
where the selecting member is rotatable between a plurality of positions including a central position, a first position, and a second position;
when in the central position, the engagement surface engages at least the first and second needles, when rotated in the first position the engagement surface engages only the first needle, and when in the second position, the engagement engages only the second needle, such that when the engagement surface engages the respective needle, axial movement of the engagement surface causes axial movement of the respective needle.

15. A suturing device for grasping tissue and deploying a length of suture into the tissue, the suturing device comprising:
-
a housing having a distal portion which is engageable with the length of suture; a tissue receiving recess disposed proximally of the distal portion, and having at least one jaw engaging surface; at least a first needle, having a tissue piercing end and a proximal end, the needle being axially movable distally and proximally across the tissue receiving recess; and a jaw having a tissue grasping portion and a cam portion having a profile, where the tissue grasping portion and cam portion are located on substantially opposite ends of the jaw; where axial movement of the jaw causes the cam portion to engage at least one of jaw engaging surface to further cause a rotational movement of the tissue grasping portion such that the tissue grasping portion moves axially and rotationally with respect to the tissue receiving recess. - View Dependent Claims (16)

17. A method of suturing soft tissue, the method comprising:
-
providing a suturing device having a tissue receiving recess and a jaw, where the jaw includes a tissue grasping portion and a cam portion having a profile, where the tissue grasping portion and cam portion are located on substantially opposite ends of the jaw; placing the tissue grasping portion against soft tissue and proximally moving the jaw relative to the tissue receiving recess, such that the cam portion of the jaw engages the suturing device to produce an simultaneous arcuate movement of the tissue grasping portion relative to the tissue receiving recess causing movement of the soft tissue into the tissue receiving recess; and advancing at least one needle through the soft tissue to engage a suture; and withdrawing the suture and needle through the tissue.
