Abstract: Radio frequency (RF) energy is transmitted through the application of a RF signal to an external RF energy interface, where the RF signal oscillates at a frequency in an energy transmission band. The transmitted RF energy is received at an implanted medical device, and energy derived from the received RF energy is stored in a direct current (DC) energy storage component of the device. A therapeutic output signal is generated from the stored energy and delivered by the implantable medical device to a patient through one or more electrodes. The therapeutic output signal is configurable to provide either one of RF stimulation therapy and RF ablation therapy, and comprises pulses of an RF signal oscillating at a frequency in a therapy band that is greater than the energy transmission band.

Abstract: An active implantable medical device configured for chronic implant in a patient includes a housing. At least one of a radio frequency (RF) module configured to generate a therapeutic output signal in a form of a pulsed a RF signal, and deliver the signal to neural tissue of the patient, and a health information module configured to collect information directed to a mechanical integrity of an orthopedic implant device and an activity of the patient, is located within the housing. The housing is configured to be associated with an orthopedic implanted device through attachment to a piece of implant hardware, or engagement with a passageway through the orthopedic implanted device. Alternatively, an active implantable medical device is incorporated and integrated into a component of an orthopedic implanted device.

Abstract: An implantable knee joint prosthesis which comprises a tibial tray, an articulating tibial insert attached to the tibial tray, and a femoral condylar component adapted to cooperatively bear upon the tibial insert. The femoral component has an intercondylar recess having parallel lateral side walls and posterior and anterior bearing members defining the boundaries of the recess. The tibial insert includes an eminence extending superiorly into the intercondylar recess and dimensioned and shaped to provide defined stabilization limits for preventing posterior-anterior dislocation while allowing limited translation and essentially free rotation and angulation throughout most of the total range of articulation. Metal reinforcements serve to secure the insert to the tray.
