Abstract
Devices are provided for a suturing device used during laparoscopic surgical procedures. A suturing needle includes a shaft forming a rod axis; a curved body having a piercing tip at a first end and a base at a second end; and an arm extending from the shaft to the base of the curved body such that the curved body is rotatable about the shaft. The suturing device includes a housing, a suturing needle, one or more sutures, a suture magazine configured to hold the one or more sutures, and a drive system, whereby the drive system may actuate the suturing needle to rotate, allowing the suturing needle to drive into and out of tissue to apply a suture.
