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: 19
Claim 1
Independent Claim
134 words
An endoscopic suture tying aid, comprising: a. a shaft having: (i) an aperture near a distal end configured to allow a suture to extend therethrough; and (ii) a needle holder near the distal end, the needle holder being axially offset from the aperture; b. a sheath in longitudinally positionable contact with the shaft and configured to be positionable at least in a first position in the vicinity of the needle holder and a second position proximal to the needle holder; c. a hook connected to a distal end of the sheath and configured to engage a suture extending through the aperture and to pull the suture when moved from the first position to the second position; and d. the shaft and needle holder being axially rotatable in two directions with respect to the hook.
Claim 2
Dependent Claim
134 words
An endoscopic suture tying aid, comprising: a. a shaft having: (i) an aperture near a distal end configured to allow a suture to extend therethrough; and (ii) a needle holder near the distal end, the needle holder being axially offset from the aperture; b. a sheath in longitudinally positionable contact with the shaft and configured to be positionable at least in a first position in the vicinity of the needle holder and a second position proximal to the needle holder; c. a hook connected to a distal end of the sheath and configured to engage a suture extending through the aperture and to pull the suture when moved from the first position to the second position; and d. the shaft and needle holder being axially rotatable in two directions with respect to the hook.
