Abstract

A suturing device includes an elongate body, an actuator, and a curved needle holder. The elongate body includes a distal end portion extending along a longitudinal axis. The actuator is operable between a first operating position and a second operating position. The curved needle holder extends away from the 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, and defines a curved needle passage and a distal opening adjacent the distal-most tip. A distance measured parallel with the longitudinal axis between where the curved needle holder begins to curve away from the longitudinal axis to either where the elongate body begins to curve away from the longitudinal axis or where the elongate body connects with a handle can be between about 10 cm to about 20 cm. Also, the distal-most tip can be offset from the longitudinal axis in a direction perpendicular to the longitudinal axis an offset distance less than about 7 mm.
