1. A suture passer comprising:
- a handle;
a shaft extending distally from the handle;
first and second jaw members mounted to the distal end of the shaft, the first jaw member having a suture support for supporting a length of suture;
a pitch adjustment mechanism for adjusting the pitch of the first and second jaw members relative to the shaft;
a lever mechanism for opening and closing the first and second jaw members relative to one another; and
a needle mechanism for selectively urging a needle having a groove therein so that the groove in the needle can engage a length of suture supported by the suture support.

17. A method for passing suture through soft tissue, the method comprising the steps of:
-
providing a suture passer comprising; a handle; a shaft extending distally from the handle; first and second jaw members mounted to the distal end of the shaft, the first jaw member having a suture support for supporting a length of suture; a pitch adjustment mechanism for adjusting the pitch of the first and second jaw members relative to the shaft; a lever mechanism for opening and closing the first and second jaw members relative to one another; and a needle mechanism for selectively urging a needle having a groove therein so that the groove in the needle can engage a length of suture supported by the suture support; positioning the needle so that it is withdrawn from the opening, positioning the first and second jaw members so that they are in their closed position, and positioning the suture in the suture support; advancing the suture passer so that the first and second jaw members are adjacent to the tissue through which the suture is to be passed; opening the first and second jaw members, adjusting the pitch of the first and second jaw members so that the first and second jaw members are aligned with the tissue, advancing the suture passer so that the first and second jaw members engage the tissue, and closing the first and second jaw members so that they securely grasp the tissue; advancing the needle so that it passes through the tissue and the groove engages the suture; and withdrawing the needle so that it passes out of the tissue, carrying the suture therewith, so that the suture is passed through the tissue. - View Dependent Claims (18, 19, 20, 31)

21. A suture passer comprising:
-
a handle; a shaft extending distally from the handle; first and second jaw members pivotally mounted to the distal end of the shaft, the first jaw member having an opening formed therein and a suture support for supporting a length of suture adjacent the opening; a slide movably mounted to the handle; a lever arm for moving the slide relative to the handle; first and second yokes movably disposed on the slide, and a yoke movement mechanism for selectively (i) urging first yoke distally and second yoke proximally, or (ii) urging first yoke proximally and second yoke distally; a first control rod for connecting the first yoke to the first jaw member, and a second control rod for connecting the second yoke to the second jaw member; a trigger pivotally mounted to the handle; a needle slidably disposed within the shaft, the distal end of the needle having a groove therein and the proximal end of the needle being secured to the trigger so that the trigger can urge the needle through the opening in the first jaw member so that the groove in the needle can engage a length of suture supported by the suture support; whereby (i) the pitch of the first and second jaw members relative to the longitudinal axis of the shaft may be adjusted via the yoke movement mechanism, (ii) the first and second jaw members may be opened and closed relative to one another via movement of the lever arm relative to the handle, and (iii) the needle can be advanced through the opening in the first jaw member so that the groove in the needle can engage a length of suture supported by the suture support via movement of the trigger relative to the handle. - View Dependent Claims (22, 23, 24, 25)

26. A method for passing suture through soft tissue, the method comprising:
-
providing a suture passer comprising; a handle; a shaft extending distally from the handle; first and second jaw members pivotally mounted to the distal end of the shaft, the first jaw member having an opening formed therein and a suture support for supporting a length of suture adjacent the opening; a slide movably mounted to the handle; a lever arm for moving the slide relative to the handle; first and second yokes movably disposed on the slide, and a yoke movement mechanism for selectively (i) urging first yoke distally and second yoke proximally, or (ii) urging first yoke proximally and second yoke distally; a first control rod for connecting the first yoke to the first jaw member, and a second control rod for connecting the second yoke to the second jaw member; a trigger pivotally mounted to the handle; a needle slidably disposed within the shaft, the distal end of the needle having a groove therein and the proximal end of the needle being secured to the trigger so that the trigger can urge the needle through the opening in the first jaw member so that the groove in the needle can engage a length of suture supported by the suture support; whereby (i) the pitch of the first and second jaw members relative to the longitudinal axis of the shaft may be adjusted via the yoke movement mechanism, (ii) the first and second jaw members may be opened and closed relative to one another via movement of the lever arm relative to the handle, and (iii) the needle can be advanced through the opening in the first jaw member so that the groove in the needle can engage a length of suture supported by the suture support via movement of the trigger relative to the handle; positioning the needle so that it is withdrawn from the opening, positioning the first and second jaw members in their closed position, and positioning the suture in the suture support; advancing the suture passer so that the first and second jaw members are adjacent to the tissue through which the suture is to be passed; opening the first and second jaw members, adjusting the pitch of the first and second jaw members so that the first and second jaw members are aligned with the tissue, advancing the suture passer so that the first and second jaw members engulf the tissue, and closing the first and second jaw members; advancing the needle so that it passes through the tissue and through the opening so that the groove engages the suture; and withdrawing the needle so that it passes out of the opening and out of the tissue, carrying the suture therewith, so that the suture is passed through the tissue. - View Dependent Claims (27, 28, 29)
