Abstract
Abstract A tube knot applicator for use in endosurgical procedures. The tube knot applicator has an elongated tube member having a distal end and a proximal end, as well as an axial passage therethrough. The tube member has slits for partially collapsing the distal end of the tube as well as a removable plug mounted in the distal end of the tube to prevent the distal end of the tube from collapsing by supporting distal slitted end. A suture having at least one slip knot and at least one locking knot is mounted in the tube knot applicator with the knot tied about the collapsing means. A sleeve is mounted to the distal end of tube knot applicator over the suture knot and the distal end.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
141 words
A method of applying an intracorporeal suture stitch comprising: inserting an elongated member into a body cavity, wherein the elongated member has a passage therethrough, a distal end and a proximal end, wherein a suture is mounted to the distal end of the elongated member such that at least two suture loops are mounted about the distal end of the elongated member secured thereto with at least one slip knot, and wherein the suture has a distal end and a proximal end; moving the distal end of the suture into the member; causing the loops and each knot to slide off of the distal end of the elongated member and onto the suture by collapsing the distal end of the elongated member after the distal end of the suture has been pulled into the elongated member; and, then tightening each knot.
Claim 2
Independent Claim
141 words
A method of applying an intracorporeal suture stitch comprising: inserting an elongated member into a body cavity, wherein the elongated member has a passage therethrough, a distal end and a proximal end, wherein a suture is mounted to the distal end of the elongated member such that at least two suture loops are mounted about the distal end of the elongated member secured thereto with at least one slip knot, and wherein the suture has a distal end and a proximal end; moving the distal end of the suture into the member; causing the loops and each knot to slide off of the distal end of the elongated member and onto the suture by collapsing the distal end of the elongated member after the distal end of the suture has been pulled into the elongated member; and, then tightening each knot.
Claim 3
Dependent Claim
19 words
The method of claim 1 wherein at least one locking knot is also contained in the suture and tightened.
Claim 4
Dependent Claim
42 words
The method of claim 1 wherein the distal end of the suture has a surgical needle mounted thereto and the needle is passed through tissue prior to moving the distal end of the suture into the distal end of the elongated member.
