Abstract

A suturing device includes a curved needle, a suture, an elongate body, an actuator and a curved needle holder. The suture connects with the curved needle. The actuator interacts with the elongate body and is operable between a first operating position and a second operating position. 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 a distal end section having a distal-most tip. The curved needle holder includes an inner surface defining a needle passage for holding the needle and a distal opening. The curved needle has a curved needle radius and the curved needle passage has a curved needle passage radius that is different than the curved needle radius and the curved needle frictionally engages the inner surface when the needle is in a retracted position.
