  • Patent number: 7524335
    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. Inorganic particles may also be included in the implant material. 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.

  • Publication number: 20040193154
    Abstract: A method and device for inserting an implant of synthetic material or healthy bone or cartilage into a bone or cartilage defect of unknown depth. The device includes an inner shaft within a hollow outer shaft. One end of the inner shaft of the device is suitable for inserting into the bone or cartilage defect in order to determine the depth, while the other end of the outer shaft is suitable for holding an implant. The implant is cut to fit the defect once its depth has been determined and then inserted into the defect. A cutting device for cutting the implant is disclosed. Also disclosed is an implant capsule loader for inserting an implant into the delivery device.

  • Publication number: 20030114937
    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 patient's body and methods of making them. 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.

  • Publication number: 20010051833
    Abstract: This invention provides molded, biodegradable porous polymeric implant materials having a pore size distribution throughout the material which is substantially uniform. These materials can be molded into implants of any desired size and shape without loss of uniformity of pore size distribution. The implants are useful as biodegradable scaffolds for cell growth in healing of tissue defects. Particulate implant materials are provided, especially useful as autologous bone graft materials.

  • Patent number: 6203573
    Abstract: This invention provides molded, biodegradable porous polymeric implant materials having a pore size distribution throughout the material which is substantially uniform. These materials can be molded into implants of any desired size and shape without loss of uniformity of pore size distribution. The implants are useful as biodegradable scaffolds for cell growth in healing of tissue defects. When manufactured to have an aspect ratio greater than about 3, the implants can be further hand-shaped to fit the defect into which they are placed and the desired shape for the regrown tissue.
