Tissue repair and replacement
First Claim
Patent Images
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.

Abstract
Tissue fixation devices are provided. The devices include a first component and a second component, the components having different rates of in vivo degradation. 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.

21. A method of tissue repair or replacement, comprising:
-
implanting into a patient a tissue repair and replacement device having at least a first component and a second component prior to implantation, the first component having a quicker in vivo degradation rate than the second component, the first component and the second component arranged about each other such that when the device is implanted, the first component degrades faster than the second component, leaving a porous tissue repair or replacement scaffold in the patient having pores for tissue ingrowth for replacement or repair; degrading the first component within the patient; forming by the in vivo degradation of the first component pores within the second component; and allowing tissue ingrowth in vivo of tissue and bone into the pores of the scaffold to secure tissue and promote healing and regrowing. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)
