Filed:

Nov 15, 2000

Appl. No.:

09/711964

Inventors:

Eugene M. Wolf - San Rafael CA

Assignee:

Arthrex, Inc. - Naples FL

International Classification:

A61B 1788

US Classification:

606 73, 128898, 606 60, 623 1314, 623 1318

Abstract:

A bioabsorbable interference screw having a tapered profile which extends along substantially the entire length of the screw. The tapered profile makes the screw easy to insert while providing superior fixation resulting from a progressively increasing diameter. Upon insertion, the screw engages cortical bone at the back end of the bone tunnel and fills all but 5-10 mm. of the tunnel, thereby providing increased fixation strength while also promoting fast healing. The screw includes a head provided with a specially designed drive socket with radially extending slots at its outer end for receiving corresponding protrusions on the shaft of screwdriver. The drive socket optimizes the torque capacity of the screw. To maintain wall thickness, the socket has a taper corresponding to the tapered outer profile of the screw. The taper of the socket also permits easy insertion of the tip and shaft of the driver into the screw.

Abstract:

A variable tilt angle shoulder prosthesis includes a variable tilt angle, comprising a head component including a proximal portion configured to interface with a glenoid process and a distal surface including a socket depression defined therein; a humeral shaft; a humeral neck at the end of the shaft including a proximal ball end which is configured to couple with the socket depression of the humeral head as a ball-in socket joint, adjustable, upon coupling with said humeral neck, to a selected tilt angle among a plurality of tilt angles relative to an elongate direction of said shaft to substantially match said prosthesis to a natural tilt angle of a humeral head of a patient.

International Classification:

A61B 17/04

US Classification:

606232

Abstract:

Methods and devices are provided for anchoring suture to bone. In one exemplary embodiment, a cannulated suture anchor is provided and it includes a suture-engaging member formed therein and configured to receive a suture therearound such that trailing ends of the suture can extend through the suture anchor. The present invention also provides exemplary sutures and drivers that can be used with the various methods and devices disclosed herein, or with other methods and devices known in the art.

Eugene Wolf - San Rafael CA, US

International Classification:

A61F002/40

US Classification:

623/019140, 606/087000, 606/099000

Abstract:

A shoulder arthroplasty apparatus includes a stemless humeral head for coupling to a previously cut humeral surface. The base of the humeral head has a stabilizing base extension that is impacted into a cancellous region of the cut humeral surface. A preferred base extension has a cruciform shape including two planar fins intersecting at or near the center of the base. The periphery of the humeral head is formed to match the cortical margins of the cut humeral surface. The humeral head is preferably cemented or press-fit to the humeral surface. The humeral head has any of a range of peripheral shapes and sizes matching the specific shape and size of the anatomic neck of a humeral surface. A method for performing the shoulder arthroplasty includes a new surgical approach using a guide to cut accurately and safely on the anatomic neck of the humerus and another guide to properly orient the reaming of the glenoid.

International Classification:

A61B 17/04

US Classification:

606232

Abstract:

Methods and devices for fixation of soft tissue to bone are provided. In one embodiment, a suture anchor is provided having an elongate cylindrical body with proximal and distal ends and an inner lumen extending therethrough. The elongate body can be configured so that upon partial insertion into a bone hole, it is securely anchored within the bone hole and a suture extending through the inner lumen is freely slidable. It can also configured so that, upon further insertion into the bone hole, at least a portion of the elongate body compresses to lock the suture within the inner lumen such that the suture is prevented from sliding. In another embodiment, a suture anchor is provided having arms that have an open position for receiving a suture therebetween, and a closed position in which the suture is retained but allowed to slide freely.
