Suture anchor attached to tissue-fixation disk without top knot
First Claim
Patent Images
1. A suture anchor assembly for attachment of tissue to bone, the suture anchor assembly comprising:
- a suture anchor comprising a body member having a distal end, a proximal end, a longitudinal axis, an outer surface and two transverse suture passages extending through the body member, the suture passages being substantially perpendicular to the longitudinal axis, each of the suture passages having a respective suture recess provided therein;
a tissue-fixation device attached to the suture anchor, the tissue-fixation device having a plurality of holes; and
a single suture strand that passes through the two transverse suture passages of the suture anchor and through the holes of the tissue-fixation device, the single suture strand attaching the suture anchor to the tissue-fixation device and terminating in at least one knot disposed within one of the suture recesses of the suture anchor.

Abstract
A suture anchor attached to a tissue-fixation disk with at least one suture knot which resides in a recess in the suture anchor, rather than on the exposed surface of the tissue-fixation disk. The suture that connects the tissue-fixation disk to the suture anchor is looped through the tissue-fixation disk and through at least one suture passage formed through the proximal end of the suture anchor, the free ends of the suture being knotted together within the suture passage of the suture anchor.

5. A suture anchor assembly for attachment of tissue to bone, the suture anchor assembly comprising:
-
a suture anchor comprising a body member having a distal end, a proximal end, a longitudinal axis, an outer surface, a socket having a shape for receiving a suture anchor driver, and at least two transverse suture passages extending through the body member, the two suture passages being substantially perpendicular to the longitudinal axis, each of the suture passages being provided with a suture recess, wherein the suture recess is configured to house a suture knot; a tissue-fixation device attached to the suture anchor, the tissue-fixation device being provided with a central aperture having a shape similar to the shape of the socket for receiving the suture anchor driver, the tissue-fixation device having a plurality of holes; and a single suture strand that passes through the two transverse suture passages of the suture anchor and through the holes of the tissue-fixation device, the single suture strand attaching the suture anchor to the tissue-fixation device and terminating in at least one knot disposed within one of the suture recesses of the suture anchor. - View Dependent Claims (6, 7, 8, 9, 15, 16, 17)

10. A method of attaching tissue to bone using a suture anchor assembly including a suture anchor having a body member, a distal end, a proximal end, a longitudinal axis, an outer surface and two transverse suture passages extending through the body member, the suture passages being substantially perpendicular to the longitudinal axis, each of the suture passages having a respective suture recess provided therein;
- a tissue-fixation device attached to the suture anchor, the tissue fixation device having a plurality of holes; and
a single suture strand that passes through the two transverse suture passages of the suture anchor and through the holes of the tissue-fixation device, the single strand attaching the suture anchor to the tissue-fixation device and terminating in at least one knot disposed within one of the suture recesses of the suture anchor, the method comprising the steps of;inserting the suture anchor assembly through the tissue; coupling the suture anchor assembly to a driver; applying tension to hold the suture anchor assembly to the driver; and installing the suture anchor assembly into bone, using the driver, to approximate the tissue to the bone. - View Dependent Claims (11)
