Abstract
Abstract A device for delivering a loop of suture material for use in endoscopic ligation is described. The device has a pair of coaxial slidable cylindrical tubes. The outer tube contains a hook for snaring the free end of the suture material; the inner tube contains a groove for retaining the suture loop circumferentially about the bore of the inner tube and also a hole beyond which the slip knot cannot move proximally. When the inner tube is pushed in a distal direction relative to the outer tube, the loop is pulled off the groove and is tightened. In use a grasping tool is inserted through the bore of the inner tube and is used to grasp a piece of tissue to be ligated. The device is then deployed, ligating the tissue piece.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
196 words
A device for ligating anatomical tissue comprising: A) a main body having a proximal end and a distal end; B) operating means on said main body near said proximal end; C) a ligature supporting body releasably mounted on said main body near the distal end of said main body and including (1) a length of ligature material releasably mounted on said ligature supporting body and including a slip knot, a tail and a loop, (2) means on said ligature supporting body for releasably supporting said ligature loop on said ligature supporting body and maintaining said ligature loop in a loop configuration, (3) means on said ligature supporting body for permitting said loop to move relative to said slip knot, (4) means on said ligature supporting body for moving the tail of said ligature material relative to said slip knot for tightening said ligature loop and releasing said ligature loop from the means on said ligature supporting body releasably supporting the ligature loop on said ligature supporting body; and D) means on said main body for co-operatively connecting said operating means to said means for moving the tail of said ligature material relative to said slip knot.
Claim 2
Independent Claim
196 words
A device for ligating anatomical tissue comprising: A) a main body having a proximal end and a distal end; B) operating means on said main body near said proximal end; C) a ligature supporting body releasably mounted on said main body near the distal end of said main body and including (1) a length of ligature material releasably mounted on said ligature supporting body and including a slip knot, a tail and a loop, (2) means on said ligature supporting body for releasably supporting said ligature loop on said ligature supporting body and maintaining said ligature loop in a loop configuration, (3) means on said ligature supporting body for permitting said loop to move relative to said slip knot, (4) means on said ligature supporting body for moving the tail of said ligature material relative to said slip knot for tightening said ligature loop and releasing said ligature loop from the means on said ligature supporting body releasably supporting the ligature loop on said ligature supporting body; and D) means on said main body for co-operatively connecting said operating means to said means for moving the tail of said ligature material relative to said slip knot.
Claim 3
Dependent Claim
19 words
The device defined in claim 1 further including means on said ligature supporting body for cutting said ligature material.
Claim 4
Dependent Claim
27 words
The device defined in claim 2 further including means on said main body for co-operatively connecting said operating means to said means for cutting said ligature material.
Claim 5
Dependent Claim
35 words
The device defined in claim 1 wherein said ligature supporting body is tubular and has a central bore defined therein, said ligature loop being positioned cirumferentially around the central bore of said ligature supporting body.
Claim 6
Dependent Claim
55 words
The device defined in claim 4 further including a second bore through said ligature supporting body and intersecting said central bore for connecting said central bore to an outside surface of said ligature supporting body, said ligature material extending through said second bore to locate the tail of said ligature material outside said central bore.
Claim 7
Dependent Claim
11 words
The device defined in claim 5 further including a tissue grasper.
Claim 8
Dependent Claim
66 words
The device defined in claim 6 wherein said tissue grasper is positioned in said central bore inside said ligature loop prior to grasping tissue to be ligated whereby the anatomical tissue will be pulled through said ligature loop when said tissue grasper is pulled into said central bore after grasping the tissue so the ligature loop will surround the anatomical tissue located inside said central bore.
Claim 9
Dependent Claim
66 words
The device defined in claim 3 wherein a portion of said operating means is mounted on said main body to move rotationally with respect to said main body and said means for connecting the operating means to the means for moving the tail of the ligature material includes means for converting rotational movement of said operating means into movement directed longitudinally of said ligature supporting body.
Claim 10
Independent Claim
100 words
A device for ligating anatomical tissue comprising: A) a main body; and B) a ligature supporting structure releasably attached to said body and including (1) a pre-knotted loop of suture material having a slip knot, a tail and a loop, (2) means for releasably mounting said loop on said supporting structure and for maintaining said loop open, (3) means on said supporting structure for holding said slip knot stationary with respect to said tail, and (4) means for moving said tail with respect to said slip knot for tightening said loop and for releasing said loop from said supporting structure.
Claim 11
Independent Claim
100 words
A device for ligating anatomical tissue comprising: A) a main body; and B) a ligature supporting structure releasably attached to said body and including (1) a pre-knotted loop of suture material having a slip knot, a tail and a loop, (2) means for releasably mounting said loop on said supporting structure and for maintaining said loop open, (3) means on said supporting structure for holding said slip knot stationary with respect to said tail, and (4) means for moving said tail with respect to said slip knot for tightening said loop and for releasing said loop from said supporting structure.
Claim 12
Dependent Claim
18 words
The device defined in claim 9 further including means on said supporting structure for cutting said suture material.
Claim 13
Dependent Claim
20 words
The device defined in claim 9 further including means for positioning said tail on the outside of said supporting structure.
Claim 14
Dependent Claim
83 words
The device defined in claim 9 wherein a second portion of said operating means is mounted on said main body for movement longitudinally of said main body and said cutter is mounted on said ligature supporting body for rotational and longitudinal movement, and said means for connecting the operating means to the means for cutting the ligature material includes means for converting longitudinal movement of said operating means into movement of said cutter which is rotational with respect to said ligature supporting body.
