Appl. No.:

09/305546

Inventors:

Neil C. Leatherbury - San Antonio TX
Kristine Kieswetter - San Antonio TX
Michael A. Slivka - San Antonio TX
Gabriele Niederauer - San Antonio TX

Assignee:

Osteobiologics, Inc. - San Antonio TX

International Classification:

A61F 202

US Classification:

623 1111, 623 664, 623 2359, 623 2375

Abstract:

This invention provides biodegradable, biocompatible polymeric films having uniform selected thicknesses between about 60 micrometers and about 5 mm useful in the manufacture of therapeutic implants for insertion into a patients body. The films may be shaped to cover implants made of other materials to improve their biocompatibility. The films may be coated with or incorporate bioactive agents. They may have differing properties, e. g. , porosity, thickness, and degradation rate, in different areas.

International Classification:

B29C 4402

US Classification:

264 51, 264102, 264108, 264321

Abstract:

A fiber-reinforced, polymeric implant material useful for tissue engineering, and method of making same are provided. The fibers are preferably aligned predominantly parallel to each other, but may also be aligned in a single plane. The implant material comprises a polymeric matrix, preferably a biodegradable matrix, having fibers substantially uniformly distributed therein. In preferred embodiments, porous tissue scaffolds are provided which facilitate regeneration of load-bearing tissues such as articular cartilage and bone. Non-porous fiber-reinforced implant materials are also provided herein useful as permanent implants for load-bearing sites.

Inventors:

Michael Andrew Slivka - Taunton MA 02780
Hassan Serhan - South Easton MA 02375

International Classification:

A61K 3800

US Classification:

514 12

Abstract:

This invention relates to a method and compositions for treating pathological intervertebral discs comprising the step of delivering an agent that causes chemical crosslinking of the native molecular components of the disc. Supplemental materials which are susceptible to crosslinking by the aforementioned agent are optionally delivered to the disc in order to increase and maintain disc height.

International Classification:

A61B 17/58

US Classification:

606 61

Abstract:

An implantable medical connector device is provided that employs a snap-on technology to safely and easily mate with another device. The medical connector device generally includes an elongate member having first and second connectors members formed on opposed ends thereof. Each connector member includes an opening formed in a sidewall thereof and extending into a nesting seat. The nesting seat is adapted to seat and engage an implanted cylindrical element.
