First Claim
Patent Images
1. A combination of a surgical suture and a suture anchor, comprising:
- I) a suture anchor, said anchor comprising an anchor body and a suture mounting passage therein; and
, II) a surgical suture, said suture comprising, an inner core comprising at least one yarn comprised of at least one fiber, said fiber comprising a bioabsorbable polymer; and
, an outer braided sheath comprising a second yarn comprised of at least one nonabsorbable fiber and a third yarn comprising at least one bioabsorbable fiber, wherein the first and second yarns are in intertwining contact, wherein the suture is mounted to the suture mounting opening of the suture anchor.

Abstract
A novel high tensile strength semi-absorbable composite suture with minimized non-absorbable mass. The suture has a core made from a bioabsorbable polymer. The core is covered by a braided sheath. The braided sheath is made from an absorbable yarn and a bioabsorbable yarn. The bioabsorbable yarn is made from a least one filament of a bioabsorbable polymer. The nonabsorbable yarn is made from at least one filament of ultra high molecular weight polyethylene.

25. A method of reducing the knot profile of a knot in a surgical suture and suture anchor combination, comprising:
-
providing a suture anchor comprising and anchor body and a suture mounting opening;
providing a suture, said suture comprising, an inner core comprising at least one yarn comprised of at least one fiber, said fiber comprising a bioabsorbable polymer; and
,an outer braided sheath comprising a second yarn comprised of at least one nonabsorbable fiber and a third yarn comprising at least one bioabsorbable fiber, wherein the first and second yarns are in intertwining contact, and wherein the suture is mounted to the anchor;
inserting said anchor in a bone having an outer surface;
stitching said suture through tissue, and affixing the tissue to the outer surface of the bone using the suture;
tying a knot in the suture, said knot having a knot profile; and
,maintaining the knot in the suture in vivo for a sufficient period of time to effectively reduce the knot profile.
