Hollow body anchor
First Claim
1. A suture anchor designed to be secure within a recess prepared in bone, said recess (i) extending inwardly from an exposed surface of the bone, (ii) comprising a cylindrical hole extending inwardly from the exposed surface to a base and surrounding a bone core extending from the base toward the exposed surface of the bone, and (iii) defining an inner bone surface and an outer bone surface, said suture anchor comprising:
- an anchor body having a fixed open top, a fixed open bottom, a cylindrical wall generally extending from the fixed open top to the fixed open bottom and defining an inner engagement surface surrounding a channel and an outer engagement surface, the outer engagement surface engages the outer bone surface of the recess and the inner engagement surface engages the inner bone surface;
wherein the anchor body is configured to be disposed within the recess such that the fixed open bottom is advanced toward the base of the recess; and
wherein the suture anchor is configured to permit at least a portion of the cylindrical wall to be inserted into the cylindrical hole of the recess such that the bone core resides in the channel.

Abstract
Attachment of sutures to bone is achieved by forming a recess in the bone having a cylindrical channel surrounding a bone core and then inserting a hollow anchor body into the recess and over the bone core. Suture material is attached using openings in the anchor body and the suture material may be pinched between the inside and outside surfaces of the anchor body and the bone material.

20. A suture anchor designed to be secure within a recess prepared in bone, said recess (i) extending inwardly from an exposed surface of the bone, (ii) comprising a cylindrical hole extending inwardly from the exposed surface to a base and surrounding a bone core extending from the base toward the exposed surface of the bone, and (iii) defining an inner bone surface and an outer bone surface, said suture anchor comprising:
- an anchor body having an open top, an open bottom, a cylindrical wall generally extending from the open top to the open bottom and defining an inner engagement surface surrounding a channel and an outer engagement surface, wherein the suture anchor body is adapted to permit at least a portion of the cylindrical wall to be inserted into the cylindrical hole of the recess such that the bone core resides in the channel, the outer engagement surface engages the outer bone surface of the recess and the inner engagement surface engages the inner bone surface, wherein said anchor body has a cylindrical extension projecting distally from a flange, and said suture anchor further comprised hollow cylindrical cap adapted to be loaded with suture material and adapted to receive the cylindrical extension, said cap having a proximal end which engages the flange when the cap is coupled to the anchor body.
