Abstract
One aspect of the present disclosure relates to a cannula for passing a tissue graft through soft tissue. The cannula can comprise an elongated body including oppositely disposed first and second ends and an axis that extends between the first and second ends. The elongated body can further include a passage extending between the first and second ends. The second end can include a curved portion that terminates at a sharpened, pointed tip configured to pierce and/or cut soft tissue at the surgical repair site. The tip can be axially offset from the axis of the elongated body at an angle that is less than 180°.

A cannula for passing a tissue graft through soft tissue, the cannula comprising:
- an elongated body including oppositely disposed first and second ends and an axis that extends between the first and second ends, the elongated body further including a passage extending between the first and second ends;
- wherein the second end includes a curved portion that terminates at a sharpened, pointed tip configured to pierce and/or cut soft tissue at the surgical repair site;
- wherein the tip is axially offset from the axis of the elongated body at an angle that is less than 180°.
A cannula for passing a tissue graft through soft tissue, the cannula comprising:
- an elongated body including oppositely disposed first and second ends and an axis that extends between the first and second ends, the elongated body further including a passage extending between the first and second ends;
- wherein the second end includes a curved portion that terminates at a sharpened, pointed tip configured to pierce and/or cut soft tissue at the surgical repair site;
- wherein the first end has a cross-section that is different than a cross-section of the elongated body and a cross-section of the second end.
A method for reinforcing soft tissue comprising:
- providing at least one cannula having a passage and a cutting end;
- forming at least one opening in the soft tissue with the cutting end of the at least one cannula;
- passing a tissue graft through the passage of the at least one cannula such that the tissue graft extends through the at least one opening in the soft tissue;
- removing the at least one cannula from the at least one opening;
- and
- securing the tissue graft to the bone to reinforce the soft tissue.
