Abstract

Tissue implants prepared for the repair of tissues, especially avascular tissues such as cartilage. One embodiment presents an electric potential capable of receiving and accumulating desirable factors or molecules from surrounding fluid when exposed to dynamic loading. In another embodiment the implant promotes tissue conduction by retarding, restricting and controlling cellular invasion through use of gradients until competent tissue forms. Further embodiments of the tissue implants may be formed into a multi-phasic device that provides deep tissue mechanical stimulus by conduction of mechanical and fluid forces experienced at the surface of the implant.
