Abstract
Abstract An endoscopic intracorporeal suture tying aid allows a suture to be looped around itself multiple times and cinched, enabling a throw of a surgeon's knot to be easily made. The tying aid includes a needle holder connected to a proximal end of a shaft for releasably holding a needle; a hook that slides longitudinally with respect to the beaks; and the shaft being axially rotatable with respect to the hook.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
127 words
A method for endoscopically forming a throw of a suture intracorporeally, comprising the steps of: (a) loading a needle, the needle having an end of a suture connected thereto, in a needle holder of a surgical instrument; (b) introducing the loaded surgical instrument to a surgical site; (c) passing the needle through tissue at the surgical site; (d) locating a hook in the vicinity of the suture; (e) engaging the suture with the hook; (f) pulling the hook proximally to create a loop in the engaged suture; (g) forming at least one loop around the suture by rotating the needle and the end of the suture around the suture; (h) pushing the hook distally so that the hook disengages the looped suture; and cinching the disengaged suture.
Claim 2
Independent Claim
127 words
A method for endoscopically forming a throw of a suture intracorporeally, comprising the steps of: (a) loading a needle, the needle having an end of a suture connected thereto, in a needle holder of a surgical instrument; (b) introducing the loaded surgical instrument to a surgical site; (c) passing the needle through tissue at the surgical site; (d) locating a hook in the vicinity of the suture; (e) engaging the suture with the hook; (f) pulling the hook proximally to create a loop in the engaged suture; (g) forming at least one loop around the suture by rotating the needle and the end of the suture around the suture; (h) pushing the hook distally so that the hook disengages the looped suture; and cinching the disengaged suture.
Claim 3
Dependent Claim
57 words
The method of claim 1, further comprising: (a) repeating steps (c) through (i) a plurality of times wherein the step of forming at least one loop is performed by rotating the needle in a first direction; and (b) repeating steps (c) through (i) a final time rotating the needle in a second direction opposite the first direction.
Claim 4
Dependent Claim
23 words
The method of claim 1, wherein the step of loading further includes loading the suture through a lumen extending through the surgical instrument.
Claim 5
Dependent Claim
17 words
The method of claim 1, wherein the step of pulling the hook further includes withdrawing the suture.
Claim 6
Dependent Claim
35 words
The method of claim 1, wherein: (a) the step of introducing further includes covering the needle holder with a sheath; and (b) before the step of passing, withdrawing the sheath to expose the needle holder.
Claim 7
Dependent Claim
46 words
The method of claim 1, wherein the step of engaging comprises rotating the needle so that the hook engages the suture; and the step of forming at least one loop comprises rotating the needle so that the engaged suture forms a plurality of loops around itself.
Claim 8
Dependent Claim
47 words
The method of claim 1, wherein the step of engaging the suture comprises rotating the hook so it engages the suture; and the step of forming at least one loop comprises rotating the hook so that the engaged suture forms a plurality loops of loops around itself.
