  • Patent number: 10383657
    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°.
