Abstract
Abstract A method for threading a suture through a suture anchor after the anchor has been driven into a bone comprises the steps of (1) providing a suture anchor having an eyelet, with at least a portion of a pre-installed suture engaging implement passed through the eyelet; (2) driving the suture anchor into a bone, leaving the eyelet and the suture engaging implement exposed; (3) engaging a suture with the suture engaging implement; (4) removing the suture engaging implement from the eyelet so as to pull the suture through the eyelet; and (5) disengaging the suture engaging implement from the suture. In one embodiment, the suture engaging implement comprises a thin, flexible tube having an open end. The tube is pre-installed in the anchor by passing it through the eyelet. One end of the suture is pushed into the open end of the tube. The tube is pulled out of the eyelet so as to pull the suture through the eyelet. The end of the suture is then removed from the open end of the tube. A second embodiment employs a loop of flexible, filamentous material as the suture engaging implement. The loop is pre-installed in the anchor by passing a portion of the loop through the eyelet. One end of the suture is passed through the portion of the loop that has been passed through the eyelet. The loop is pulled out of the eyelet so as to pull the suture through the eyelet. The suture is then removed from the loop.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
114 words
A method for threading a suture having a first end and a following portion through an eyelet of a suture anchor, comprising the steps of: (a) providing a suture anchor having an eyelet, with at least a portion of a pre-installed suture engaging implement installed in the eyelet; (b) driving the suture anchor into a bone mass so as to leave the eyelet and the suture engaging implement exposed; (c) engaging the suture engaging implement with a suture; (d) removing the suture engaging implement from the eyelet so as to pull the first end of the suture and the following portion through the eyelet; and (e) disengaging the suture engaging implement from the suture.
Claim 2
Independent Claim
114 words
A method for threading a suture having a first end and a following portion through an eyelet of a suture anchor, comprising the steps of: (a) providing a suture anchor having an eyelet, with at least a portion of a pre-installed suture engaging implement installed in the eyelet; (b) driving the suture anchor into a bone mass so as to leave the eyelet and the suture engaging implement exposed; (c) engaging the suture engaging implement with a suture; (d) removing the suture engaging implement from the eyelet so as to pull the first end of the suture and the following portion through the eyelet; and (e) disengaging the suture engaging implement from the suture.
Claim 3
Dependent Claim
47 words
The method of claim 1, wherein the suture engaging implement comprises an elongate, flexible, elastomeric hollow tube having an open end dimensioned to receive the suture, and wherein the step of engaging comprises: pushing the first end of the suture into the open end of the tube.
Claim 4
Dependent Claim
33 words
The method of claim 2, wherein the open end of the tube includes a flared opening, and wherein the pushing step comprises: pushing the first end of the suture into the flared opening.
Claim 5
Dependent Claim
30 words
The method of claim 2, wherein the step of removing comprises the step of: stretching the tube so as to elastomerically contract its inside diameter, thereby frictionally gripping the suture.
Claim 6
Independent Claim
126 words
A method for threading a suture having a first end and a following portion through an eyelet of a suture anchor, comprising the steps of: (a) providing a suture anchor with an eyelet and an elongate, flexible, elastomeric, hollow tube having an open end, at least a portion of the tube having been installed in the eyelet; (b) driving the suture anchor into a bone mass so as to leave the eyelet and the tube exposed; (c) pushing the first end of the suture into the open end of the tube; (d) removing the tube from the eyelet so as to pull the first end of the suture and the following portion of the suture through the eyelet; and (e) removing the suture from the tube.
Claim 7
Independent Claim
126 words
A method for threading a suture having a first end and a following portion through an eyelet of a suture anchor, comprising the steps of: (a) providing a suture anchor with an eyelet and an elongate, flexible, elastomeric, hollow tube having an open end, at least a portion of the tube having been installed in the eyelet; (b) driving the suture anchor into a bone mass so as to leave the eyelet and the tube exposed; (c) pushing the first end of the suture into the open end of the tube; (d) removing the tube from the eyelet so as to pull the first end of the suture and the following portion of the suture through the eyelet; and (e) removing the suture from the tube.
Claim 8
Dependent Claim
34 words
The method of claim 5, wherein the open end of the tube includes a flared opening, and wherein the step of pushing comprises: pushing the first end of the suture into the flared opening.
Claim 9
Dependent Claim
39 words
The method of claim 5, wherein the step of pushing comprises: pushing the first end of the suture and at least about 9 to 10 mm in length of the following portion, into the open end of the tube.
Claim 10
Dependent Claim
26 words
The method of claim 7, wherein the step of removing comprises: pulling the first end of the suture out of the open end of the tube.
Claim 11
Dependent Claim
32 words
The method of claim 5, wherein the step of removing the tube comprises the step of: stretching the tube so as to elastomerically contract its inside diameter, thereby frictionally gripping the suture.
Claim 12
Independent Claim
126 words
A method for threading a suture having a first end and a following portion through an eyelet of a suture anchor, comprising the steps of: (a) providing a suture anchor having an eyelet and a flexible, filamentous loop, at least a portion of which has been installed in the eyelet; (b) driving the suture anchor into a bone mass so as to leave the eyelet and the filamentous loop exposed; (c) passing the first end of the suture through the portion of the loop that has been installed in the eyelet; (d) removing the loop from the eyelet so as to pull the first end of the suture and the following portion of the suture through the eyelet; and (e) removing the suture from the loop.
