Abstract
A suturing device includes a shaft with a pair of axial passages extending through the shaft. A length of suture passes through the first axial passage, the suture having a surgical needle attached to its distal end, and a preformed knotted loop disposed at a distal end of the first axial passage. The second axial passage includes a gaseous seal and is configured to receive a surgical instrument for manipulating tissue to facilitate application of the suture. In the method of the invention, the suturing device is inserted through a cannula and a surgical instrument is introduced through the second axial passage. Tissue is manipulated using the surgical instrument to facilitate application of the suture. A needle holder introduced through a separate cannula is used to pass the needle through the wound and through the knotted loop. Tension is then applied to the suture to close the knot and bind the wound.
