    Abstract: A tissue closure device includes a pusher assembly having a drive arm extending from a drive shaft and a needle driver at a distal end of the drive arm, wherein the needle driver is capable of releasably engaging and rotating a suturing needle having a pointed end and a blunt end about a rotational axis and a cartridge having a protective housing and the suturing needle, the cartridge extending from a distal end of a cartridge holder assembly and releasably attached to the cartridge holder assembly. A pointed end of the suturing needle may be positioned within the protective housing before and after a complete rotation of the suturing needle about the rotational axis. A removable electronic module may be provided controlled by an actuator that mechanically engages the drive shaft to rotate the drive shaft and the needle driver, thereby rotating the suturing needle about the rotational axis.

    Abstract: An apparatus and a method for surgical fastening is disclosed. An illustrative apparatus for tissue suturing includes a cartridge having a suturing needle having a pointed end and a blunt end, the suturing needle capable of rotating about an axis, a reciprocating needle drive, and an actuator capable of releasably engaging the needle drive to rotate the needle. A method for suturing tissue is provided that includes placing a suturing device having a cartridge containing a suturing needle to span at least one tissue segment, activating an actuator to cause rotational movement of the suturing needle through the at least one tissue segment, and deactivating the actuator to stop an advancing movement of the suturing needle to cause a suturing material to be pulled through the at least one tissue segment forming a stitch.
