9. A knot tier comprising:
-
a shaft having a distal end and a proximal end; a handle mounted at the proximal end of said shaft, in the form of a ring, sized to fit the thumb of a user; first guide means located at the distal end of said shaft, said first guide means being an aperture; and second guide means located at the distal end of said shaft, said second guide means having two legs in close proximity to said first guide means, said legs angled distally; and snagging means, wherein said snagging means comprise the crotch of said two legs and the entrance to said second guide means defined by said two legs.

10. A knot tier comprising:
-
a shaft having a distal end and a proximal end; a handle mounted at the proximal end of said shaft adapted to fit around a thumb of a user; a first guide located at the distal end of said shaft, said first guide being an aperture; a second guide located at the distal end of said shaft, said second guide having two legs in close proximity to said first guide, said legs being angled distally; and a snagging means comprising a crotch of said two legs and an entrance to said second guide defined by said two legs. - View Dependent Claims (4, 5, 6, 7, 8, 11, 12, 13, 14, 15, 16)

17. A method for tying a slip knot, the method comprising the steps of:
-
providing a knot tier comprising; a shaft; a handle mounted on a proximal end of said shaft; a first guide located at a distal end of said shaft and comprising an aperture; a second guide located at the distal end of said shaft, said second guide having two legs in close proximity to said first guide, said legs being angled distally; and a snagging means comprising a crotch of said two legs and an entrance to said second guide defined by said two legs; forming a slip knot with a wrapping limb about a post limb and defining a loop, said post limb extending through said aperture, and said wrapping limb extending between said two legs, and said knot being adjacent said snagging means; cinching the loop to a desired tension by pulling on the post limb and pushing the knot along the post limb; and locking the knot on the post limb by pulling the wrapping limb, pushing the knot away from the wrapping limb, then relaxing the post limb, to distort the post limb. - View Dependent Claims (18, 19, 20, 21)

22. A method for tying a slip knot in a surgical suture, and advancing the knot to a remote surgical site removed from an operator, the method comprising the steps of:
-
providing a knot tier comprising; a shaft; a handle mounted on a proximal end of said shaft; a first guide located at a distal end of said shaft and comprising an aperture; a second guide located at the distal end of said shaft, said second guide having two legs in close proximity to said first guide, said legs being angled distally; and a snagging means comprising a crotch of said two legs and an entrance to said second guide defined by said two legs; forming a slip knot in the suture with a suture wrapping limb about a suture post limb and defining a suture loop, said post limb extending through said aperture, said wrapping limb extending between said two legs, and said knot being adjacent said snagging means; cinching the suture loop to a desired tension by pulling on the post limb and pushing the knot along the post limb toward the remote site; and locking the knot on the post limb at the remote site by pulling the wrapping limb, pushing the knot away from the wrapping limb, then relaxing the post limb, to distort the post limb. - View Dependent Claims (23, 24, 25, 26)

27. A method for tying a slip knot in a surgical suture, and advancing the knot to a remote surgical site removed from an operator, the method comprising the steps of:
-
providing a knot tier comprising; a shaft; a handle mounted on a proximal end of said shaft and adapted to fit around a thumb of an operator; a first guide located at a distal end of said shaft and comprising an aperture; a second guide located at the distal end of said shaft, said second guide having two legs in close proximity to said first guide, said legs being angled distally; and a snagging means comprising a crotch of said two legs and an entrance to said second guide defined by said two legs; forming a slip knot in the suture with a suture wrapping limb around a suture post limb and defining a suture loop, said post limb extending through said aperture and proximally along said shaft, the operator permitting said suture post limb to rest on and hang from an operator'"'"'s finger proximate the operator'"'"'s thumb, said wrapping limb extending between said two legs, and said knot being adjacent said snagging means; cinching the suture loop to a desired tension by pulling on the post limb with said finger and pushing the knot with said snagging means along the post limb toward the remote site; and locking the knot on the post limb at the remote site by pulling the wrapping limb, pushing the knot away from the wrapping limb, then relaxing the post limb, to distort the post limb. - View Dependent Claims (28, 29)
