Abstract
A fixation device for fixation of soft tissue to bone with a body formed essentially of resorbable or non-resorbable yarns. The fixation device may be a knotted or a knotless construct. The fixation device is a soft, yarn-based whipping anchor which is formed by providing a suture eyelet, and passing a plurality of passes of yarns around the suture eyelet (forming a whipping twine), using the suture eyelet as a mandrel, to create a robust construct which may have geometrically-shaped features such as barbs. The eyelet and the twine may be made from resorbable material, non-resorbable material, or combination of resorbable and non-resorbable materials.
Claims21
A suture anchor consisting essentially of:
- a material strand with two ends abutting one another to form a free ends region and an eyelet;
- multiple twine passes provided along and around the free ends region and adjacent the eyelet of the material strand, wherein the multiple twine passes are formed by whipping at least one twine around the material strand to prevent the two ends of the material strand to become apart;
- and
- at least another flexible strand threaded through the eyelet for further securement of soft tissue to bone.
A suture anchor for surgical repairs consisting essentially of:
- a body formed of at least one whipping twine in the form of resorbable yarns;
- a flexible strand extending through the body, wherein the flexible strand has two free ends that form a closed eyelet located at one end of the body and the at least one whipping twine extends around the two free ends and not between the two free ends;
- and
- at least one tying or sliding suture threaded through the closed eyelet for further securement of soft tissue to bone.
A method of fixation of a first tissue to a second tissue, comprising the steps of:
- providing a suture anchor comprising a length of a flexible strand folded to form a closed eyelet and a free ends region and at least one body member formed at least partially around and at least partially along the length of the flexible strand and around two ends of the free ends region without extending between the two ends of the free ends region and adjacent to the closed eyelet, the closed eyelet being located at a most proximal end of the suture anchor, the body member consisting essentially of yarns;
- threading suture through the closed eyelet;
- placing the suture anchor into bone;
- and
- securing soft tissue to bone with the suture.
A method of forming a suture anchor, comprising the steps of:
- bringing together two free ends of a flexible strand so that the two free ends abut one another and form a free ends region and an eyelet adjacent the free ends region;
- and
- using the eyelet as a mandrel, conducting a plurality of passes with at least one twine around the free ends region and along a length of the free ends region and adjacent the eyelet, to form a whipping twine body abutting the eyelet, the plurality of passes preventing the two free ends of the flexible strand from becoming apart.
