Abstract
Abstract A surgical suture or the like including a pair of butterflyloops secured in superimposed registering relation by a casing through which the loops are visible, and a pair of tails extending from the loops. A suturing method wherein one of the tails is used as a suture which pierces the tissue to be sutured and is passed through the superimposed loops, the tails then being pulled tight to convert the interlooping formation into a square knot.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
14 words
A tie element as defined in claim 1, for use as a surgical suture.
Claim 2
Dependent Claim
76 words
A suture as defined in claim 2, wherein one of said tails is a relatively long one, of a length suitable for attachment to a needle and for piercing tissue material, forming therewith a suture loop around said tissue, and passing it through said butterfly loops to start the formation of a square knot; and wherein the other tail is relatively short, of a length suitable for grasping to apply a pull to said butterfly loops.
Claim 3
Dependent Claim
19 words
A tie element as defined in claim 1, wherein said casing is in the form of a thin wafer.
Claim 4
Dependent Claim
21 words
A tie element as defined in claim 1, wherein said casing is in the form of a sheath of ring form.
Claim 5
Independent Claim
145 words
A method of surgical suturing comprising: utilizing a suture including a preformed folded butterfly-loop formation comprising a pair of loops superimposed one upon the other in registering relation, and a bight connecting said loops; and a tail extending from each of the respective loops, said bight being looped over said tails; initially securing the loops of said folded butterfly-loop formation in said superimposed relation by means yielding to a pull on said tails to allow the evolution into a square knot; placing said butterfly-loop formation against a tissue member to be sutured; piercing said tissue with one of said tails, looping said one tail around the tissue to form a suture loop, and passing it through said superimposed butterfly loops; and pulling on said tails to reduce said suture loop to tissue-suturing size and to evolve the loop and tail formation in a square knot.
Claim 6
Dependent Claim
18 words
The method defined in claim 6, wherein said initial securing means is a coating of frangible, nontoxic material.
Claim 7
Dependent Claim
35 words
The method defined in claim 6, wherein the tail used to form the suture loop is pulled in order to tighten said loop and the other tail is then pulled to develop said square knot.
