Tissue repair and replacement

摘要

The first component and second component are arranged so that, upon degradation of one of the components, the other component provides a scaffold into which bone can grow.

主权项

1. A method of tissue repair or replacement, comprising: implanting in a patient a tissue repair or replacement device having at least a first and a second components, the first component having a higher rate of in vivo degradation than the second component, and the first and second components being arranged relative to each other so that, after implantation of the device, the first component degrades in vivo leaving a scaffold formed of the second component, the scaffold having pores into which tissue can infiltrate,
wherein a portion of the first or second component of the tissue replacement or repair device covers the entire outer surface of the other component except in defined areas where ribs of a production mold contacted the outer surface of the covered component of the tissue replacement or repair device.
