A new device and method for extracorporeal knot tying in laparoscopic surgery.

Advances in laparoscopic suturing will be facilitated by the ability to tie knots rapidly and effectively. A new device is presented that enhances extracorporeal laparoscopic knot tying, using familiar surgeon's or square knots in any size or type of suture material. It speeds knot formation and allows precise control of knot placement in a wide variety of applications.
