  • Endoscopic suturing device
    Patent number: 5234445
    Abstract: A medical device for ligation or approximating tissue is disclosed. The device has a cannula with proximal and distal ends.

The device includes a suture with a slide end and a distal loop, as well as a slip knot securing the loop to the slide end. The slide end is threaded thorough the first and second channels of the cannula and it protrudes from the proximal end of the cannula.
