Abstract
The technology includes an anchor assembly for tissue repair having an open helical coil sleeve and a tip structure. The tip structure includes an aperture for passing a suture and a suture capture member for capturing a suture. The technology also includes an anchor driver for installing an anchor into bone. The anchor driver includes an outer shaft and a sleeve advancement member for advancing the sleeve as well as an inner shaft and a suture capture advancement member for advancing the suture capture member. The technology also includes a system for tissue repair having an anchor assembly and an anchor driver for installing the anchor assembly into bone.
Claims20
A surgical anchor assembly, comprising:
- a sleeve comprising:
- a proximal end, a distal end, and a longitudinal axis extending therebetween;
- a cannulation extending along the longitudinal axis between the proximal and distal ends;
- and
- a first engagement feature formed in the cannulation at the distal end of the sleeve;
- a tip comprising a first portion having a second engagement feature formed on an outer surface of the first portion and engageable with the first engagement feature, and a second portion defining an eyelet for passage of a flexible member, a distal terminus of the second portion defining a flat end;
- and
- a cannulated fixation member having at least a portion that is proximal to the eyelet.
A method of tissue repair comprising:
- inserting a tip of a surgical anchor assembly into a bone hole, the surgical anchor assembly comprising:
- a sleeve comprising:
- a proximal end, a distal end, and a longitudinal axis extending therebetween;
- a cannulation extending along the longitudinal axis between the proximal and distal ends;
- and
- a first engagement feature formed in the cannulation at the distal end of the sleeve;
- the tip comprising a first portion having a second engagement feature formed on an outer surface of the first portion and engageable with the first engagement feature, and a second portion defining an eyelet for passage of a flexible member, a distal terminus of the second portion defining a flat end;
- and
- a cannulated fixation member having at least a portion that is proximal to the eyelet;
- capturing the flexible member within the eyelet;
- and
- advancing the sleeve into the bone hole and into engagement with the tip.
