Filed:

Apr 19, 2001

Appl. No.:

09/838698

Inventors:

N. Grusin - Memphis TN, US
Christopher Jobe - Redlands CA, US
Michael Brooks - Memphis TN, US
Felix Rivas - Cordova TN, US
Edward Duke - Bartlett TN, US

International Classification:

A61F002/40

US Classification:

623/019140

Abstract:

A modular humeral prostheses for replacement of the humeral head of a humerus. The prosthesis generally comprises a stem for insertion in the medullary canal of the humerus, a head for replacing the natural humeral head, and a connecting member for connecting the head to the stem. Specifically, the connecting member of the prosthesis and the engagement of the connecting member to the head provides varying degrees of eccentricity as desired.

International Classification:

A61B017/04

US Classification:

606/139000, 606/148000

Abstract:

The present invention is related to methods and apparatus that can enhance the security of a suture knot by annealing a portion of the suture knot. Such a suture knot is less likely to fail by slippage. Advantageously, the methods and apparatus can operate in a liquid environment, such as the inside of a body. Conventional knots made from monofilament sutures exhibit an unfortunate tendency to slip or untie. A surgeon can tie a conventional monofilament suture using standard knot tying techniques and anneal the suture. The annealing can fuse the tails of the suture together, thereby preventing failure by slippage. In one embodiment, the annealing textures the surface of the monofilament tails, thereby increasing friction and resistance to slippage. In another embodiment, the annealing is applied to the last throw in the knot.

International Classification:

A61F002/36

US Classification:

623/019140, 623/022410, 623/023260

Abstract:

A series of humeral stems, each stem including an axial bore and longitudinal slots along the distal end to allow for distal compression. The compression force necessary to compress the distal diameter of each stem varies by stem diameter. Thus, as the stem diameter increases through the series, the compression force decreases. The axial bore and longitudinal slots together form a series of stem segments that assume the shape of the medullary canal, reducing the force exerted upon the canal by the humeral stem.
