Suture anchor with attached disk
First Claim
1. A suture anchor assembly for attachment of tissue to bone, the suture anchor assembly comprising:
- a suture anchor having a distal end and a proximal end, the proximal end having an opening for receiving at least one filament, and a socket having a shape for receiving a suture anchor driver;
at least one filament looped slidingly through the opening and having a first end and a second end; and
a tissue-retaining device attached to the first end and the second end of the filament and provided with a central aperture having a shape similar to the shape of the socket for receiving the suture anchor driver.

Abstract
A suture anchor assembly for attachment of tissue to bone includes a suture anchor having a distal end and a proximal end, the proximal end having an opening. A filament strand is looped through the opening and is attached at either end to a disk. The disk has a central opening that accommodates a suture anchor driver. The driver engages the suture anchor for installation through the tissue and into the underlying bone. As the suture anchor is installed into bone, tissue is approximated to the bone by the captured disk. Traction suture attached to the disk allows testing of the installation, and retrieval of the assembly in the event of failure during installation.

7. A suture anchor assembly and driver combination comprising:
-
a suture anchor having a distal end and a proximal end, the proximal end having an opening, and a driving attachment for receiving a suture anchor driver; at least one filament looped slidingly through the opening and having a first end and a second end; a tissue-retaining device attached to the first end and the second end of the filament, the tissue-retaining device having a central aperture sized and shaped so as to accept the driver; and a driver having a distal end and a proximal end, the distal end being disposed through the central aperture of the tissue-retaining device and engaging the driving attachment of the suture anchor. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A method of attaching tissue to bone using a suture anchor assembly including a suture anchor having a distal end and a proximal end, the proximal end having an eye, at least one filament looped slidingly through the eye and having a first end and a second end, and a tissue-retaining device attached to the first end and the second end of the suture strand said tissue-retaining device being attached to a traction suture, 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 the traction suture 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.

15. A suture anchor assembly for attachment of tissue to bone, the suture anchor assembly comprising:
-
a suture anchor having a distal end and a proximal end, the proximal end having an opening; at least one filament looped slidingly through the opening and having a first end and a second end; and a tissue-retaining device attached to the first end and the second end of the filament by respective knots in the filament. - View Dependent Claims (16, 17, 18, 19)

20. A method of attaching tissue to bone using a suture anchor assembly including a suture anchor having a distal end and a proximal end, the proximal end having an eye and a socket having a shape, at least one filament looped slidingly through the eye and having a first end and a second end, and a tissue-retaining device attached to the first end and the second end of the suture strand and having a central aperture, the shape of the central aperture being similar to the shape of the socket, the method comprising the steps of:
-
coupling the suture anchor assembly to a distal end of an installation driver by inserting the distal end of the driver through the central aperture of the tissue retaining device and into the socket of the suture anchor; inserting the suture anchor assembly through the tissue using the driver; and installing the suture anchor assembly into bone by turning the assembly with the driver to approximate the tissue to the bone. - View Dependent Claims (21)
