Abstract: A cycling suturing and knot-tying device is characterized by an arcuate fixed, grooved or recessed way provided in a correspondingly-shaped support frame for accommodating a curved needle fitted with thread, and frictional needle-engaging devices provided in the way for selectively engaging the needle and driving the needle in one or both rotational directions to suture a wound with the thread. Selective articulation of the frame and the way and driving of the needle in the way by positioning the frictional needle-engaging devices with respect to the needle are typically effected by manipulation of a pistol-grip operating apparatus having a transmission tube that mounts the frame and the way in articulating relationship and rotates and articulates with respect to the pistol grip and carries various operating elements that interface with the frictional needle-engaging devices in the way.

Abstract: Embodiments of a suturing device and methods of suturing are disclosed. The device comprises an arcuate needle, a plurality of one way gate mechanisms radially spaced around a portion of the arcuate needle, where each one way gate mechanism engages the needle in one direction, and a driving means for driving the plurality of one way gate mechanism around a portion of the needle such that the needle is incremented along a rotational direction.
