Abstract
Abstract A method and apparatus for facilitating use of a threaded suture anchor in combination with a reusable cannulated anchor driver. The device enables a suture anchor to be preassembled with a suture so that a user need not assemble a suture anchor with suture immediately prior to use. The preassembled anchor/suture is provided with a suture stiffening or support member by which the free ends of the suture may be easily threaded into the axial bore of a cannulated driver. The support member may comprise a length of shrinkable tubing frictionally engaging at least a portion of the free ends of the suture extending from the anchor. In another embodiment, the support means may comprise an elongated non-shrinkable material such as a rod attached to the suture and enabling the anchor/suture/rod assembly to be threaded into a cannulated driver simply by the force of gravity acting upon the rod.

Claim 5
Dependent Claim
88 words
A pre-loaded suture anchor assembly for attachment to an anchor driver comprising: an anchor body having a suture receiving means for receiving suture; a suture having predetermined length and having a first end and a second end, said suture received in said suture receiving means and extending therefrom: a hollow, elongated substantially straight tubular sleeve means having an axial bore with open distal and proximal ends for holding both of said ends of said suture by frictionally engaging said ends within said axial bore of said sleeve means.
Claim 6
Dependent Claim
26 words
A pre-loaded suture anchor assembly according to claim 3 wherein said distal end of said sleeve means frictionally engages a predetermined portion of said anchor body.
Claim 7
Dependent Claim
21 words
A pre-loaded suture anchor assembly according to claim 3 wherein said distal end of said sleeve means comprises a heat-shrinkable tube.
Claim 8
Dependent Claim
72 words
A pre-loaded suture anchor assembly according to claim 3 wherein said suture receiving means comprises an eyelet member and wherein said eyelet member receives an intermediate portion of said suture such that a pair of suture portions are formed from said suture one suture portion extending between said anchor body and said first suture end and the other of said suture portions extending between said anchor body and said second suture end.
Claim 9
Dependent Claim
24 words
A pre-loaded suture anchor assembly according to claim 6 wherein said sleeve means frictionally engages both, said first and second ends of said suture.
Claim 10
Independent Claim
118 words
A method of producing a pre-loaded suture anchor assembly for attachment to a suture anchor driver comprising the steps of: providing a suture anchor having a suture receiving means for receiving suture; providing a predetermined length of suture; engaging a predetermined length of suture with said suture receiving means so that at least one end of said suture extends from said suture anchor; providing a predetermined length of suture-supporting means for decreasing the lateral flexibility of an end portion of said suture to enable said suture to be engaged end-to-end with said driver; placing said at least one end of said suture into one end of said suture-supporting means; causing said suture-supporting means to frictionally engage said suture.
Claim 11
Independent Claim
