    摘要: A density gradient biopolymeric matrix implant is disclosed. The implant includes a first homogeneous matrix layer and a second homogeneous matrix layer having a density different from that of the first homogeneous matrix layer. Biopolymeric fibers at the surface of the first homogeneous matrix layer are physically in contact with and cross-linked to the biopolymeric fibers at the surface of the second homogeneous matrix layer. Also disclosed is a three-dimensional density gradient biopolymeric matrix implant that includes a first homogeneous matrix surrounding a second homogeneous matrix having a different density. Biopolymeric fibers at an inner surface of the first homogeneous matrix are physically in contact with and cross-linked to biopolymeric fibers at an outer surface of the second homogeneous matrix. Furthermore, methods for preparing the density gradient biopolymeric matrix implant and the three-dimensional density gradient biopolymeric matrix implant are provided.

    摘要: A medical implant apparatus includes or uses an energy transmission device for wireless transmission of energy of a first form from outside a patient's body. An implanted medical device is operable in response to energy of a second form different than the energy of the first form. An implanted energy transforming device transforms energy of the first form wirelessly transmitted by the energy transmission device into energy of the second form for use in the control and operation of the medical device.
