Abstract
A method, system and apparatus for suturing tissue in an anatomical cavity during an endoscopic procedure includes a suturing instrument extending through a portal in the anatomical cavity wall for manipulating a needle to penetrate the tissue to form a looped portion of a length of suture material at an exit point in the tissue and to back the needle out of the tissue, and an anchor applier instrument extending through another portal in the anatomical cavity wall for positioning an anchor in engagement with the looped portion of the suture material to allow the suture material to be tensioned and secured to adjustably approximate the tissue.
Claims4
In combination, a length of suture material and an anchor applier instrument for use in suturing tissue in an anatomical cavity during an endoscopic procedure comprising
- a length of suture material for being passed through the tissue to form a looped portion disposed externally of the tissue;
- and
- an anchor applier instrument for being inserted through a portal in a wall of the anatomical cavity to engage said looped portion and including a barrel housing a plurality of anchors therein for anchoring said suture material in the tissue, said barrel having a distal end for ejecting said anchors and a length to extend through the portal to a proximal end, a handle receiving said barrel proximal end for manipulating said anchor applier instrument within the anatomical cavity, and anchor receiver means positioned at said barrel distal end for receiving anchors ejected therefrom, said anchor receiver means having tapered tip means for insertion in said looped portion of said length of suture material to position said looped portion in engagement with anchors received by said anchor receiver means, said anchor receiver means including a pair of opposing jaws for receiving an anchor therebetween, one of said jaws extending beyond the other of said jaws to form said tapered tip means.
In combination, a length of suture material and an anchor applier instrument for use in suturing tissue in an anatomical cavity during an endoscopic procedure comprising
- a length of suture material for being passed through the tissue to form a looped portion disposed externally of the tissue;
- and
- an anchor applier instrument for being inserted through a portal in a wall of the anatomical cavity to engage said looped portion and including a barrel housing a plurality of anchors therein for anchoring said suture material in the tissue, said barrel having a distal end for ejecting said anchors and a length to extend through the portal to a proximal end, a handle receiving said barrel proximal end for manipulating said anchor applier instrument within the anatomical cavity, and anchor receiver means positioned at said barrel distal end including a jaw forming a cradle for receiving an anchor therein and terminating at a tapered tip for insertion in said looped portion of said length of suture material to position said looped portion in engagement with an anchor received in said cradle.
