First Claim
Patent Images
1. A method for suturing tissue comprising:
- (a) providing a length of suture material having a leading end and a trailing end, at least part of said length being resiliently biased to a coiled state, said at least part of said length being straightenable under tension and returning to said coiled state when released;
(b) drawing said leading end through or around at least one region of tissue so that a leading portion of the suture material lies between the tissue and said leading end and a trailing portion of the suture material lies between the tissue and said trailing end; and
(c) forming a knot in said suture material, said forming a knot including at least one sequence of;
(i) passing at least part of one of said leading and trailing portions through at least one resiliently-formed coil formed in the other of said leading and trailing portions, and(ii) pulling tight said leading and trailing portions.

Abstract
A suture for facilitating tying of knots includes a length of suture material fixed to a needle. At least part of the length of the suture material is resiliently biased to a coiled state which is straightenable under applied tension but which returns to its coiled state when released. In use, part of the suture material is drawn through a region of tissue so that portions of the suture material lie on opposite sides of the tissue. A knot is then formed in the suture material by passing one of the portions through at least one resiliently-formed coil formed in the other of the portions, and pulling tight the suture material.

14. A suture for facilitating tying of knots, the suture comprising:
-
(a) a needle; and (b) a length of suture material fixed to said needle, wherein at least part of said length of suture material is resiliently biased to a coiled state, said at least part of said length being straightenable under tension and returning to said coiled state when released. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)

23. A method for producing a suture for facilitating tying of knots, the method comprising:
-
(a) forming a length of material into a coiled form including a plurality of coils; and (b) processing said length of material so as to impart to said length of material an elastic memory such that said length of material is resiliently biased to said coiled state, being straightenable under applied tension and returning to said coiled state when released. - View Dependent Claims (24, 25, 26)
