Abstract
A suturing device includes a needle, a suture, an elongate body, an actuator and a curved needle holder. The needle has first end, which is pointed, a second end, a curved distal section and a straighter proximal section, which is straight or has a radius of curvature greater than the curved distal section. The suture connects with the needle. The actuator includes a mechanism operable to move the needle with respect to the elongate body. The curved needle holder extends away from a distal end portion or is provided as part of the distal end portion of the elongate body. The curved needle holder includes an inner surface defining a curved needle passage for holding the needle and a distal opening through which the needle exits the curved needle holder. The needle frictionally engages the inner surface when the needle is in a retracted position.
