Abstract
Abstract An implement for setting sutures particularly suitable for use in situations where access to the tissue to be sutured is difficult. The implement includes a pair of hinged arms, each having a handle portion and a jaw portion. The tip of one jaw has a tissue piercing hook and the tip of the other jaw has a notch or opening through which the hook may pass. A series of guides and openings position the suture above the opening for engagement by the hook. When the jaws are closed about the tissue, the hook will pass through the tissue and the suture will ride around the hook. The suture will be engaged by the hook and upon opening the jaws, the hook will pull a loop of suture through the tissue, the loop may then be cut and the suture fixed in the usual manner.

Claim 1
Independent Claim
271 words
An implement for setting a suture in tissue, said implement comprising: (a) first and second hinged arms, each arm defining a handle portion and a jaw portion; (b) said jaw portion of said first arm having a opening therein; (c) said jaw portion of said second arm including a hook constructed and arranged to pierce tissue and being sized to pass through said opening of said jaw portion of said first arm when the jaws are closed; (d) suture positioning means disposed on at least one of said first and second arms; said positioning means disposing a portion of said suture proximate said opening in said jaw portion of said first arm; (e) said positioning means including an opening disposed between the inner and outer surfaces of said first arm, a projection disposed at the tip of said first arm extending perpendicularly from said jaw portion of said first arm and having an aperture therein, and tubular means disposed on the said of the jaw portion of said opening of said first arm, said positioning means permitting said suture to be threaded through said opening disposed between the inner and outer surfaces of said first arm, through said opening in said projection and thereafter through said tubular means to thereby securely position said suture for engagement with said hook; and (f) said hook piercing said tissue when said jaws are closed, said hook passing through said tissue and said hook engaging said portion of said suture disposed proximate said opening, upon the opening of said jaws said hook retracting a loop of said suture through the opening pierced in said tissue.
