Abstract: A method for draining autologeous biological fluid includes positioning a catheter to receive the autologeous biological fluid from a selected site in a mammalian body with the end of the catheter adapted to receive such fluid. An output end of the catheter is positioned into the intraosseus space. The fluid is transmitted through the catheter to intraosseus space thereby draining the selected site from the autologous biological fluid.

Abstract: A method for monitoring and controlling biological substances found in the bloodstream include implanting in-vivo a pedestal such that a sensor mounted on the pedestal extends into the bone marrow for sensing the biological substance. A transmitter is included for transmitting signals from the sensor to a receiver. An apparatus that includes a monitoring device and a drug delivery device and components to communicate between the monitoring and drug delivery devices.

Abstract: An implantable electronic device includes a geodesic shaped dome housing and means for attaching the dome to a target neurologic structure. The dome includes a radio frequency receiver, an amplifier, and a stimulating electrode. A radio frequency based neurostimulatory system further includes a transmitting coil positioned outside a patient's body for transmitting pulses to the receiver and activating the stimulating electrode within the implantable electronic device. A method of stimulating a patient's neurologic structure includes implanting an electronic device proximate the neurologic structure, positioning a transmitting coil outside the patient's body for controlling the implantable device, initiating radio frequency waves from a pulse generator to the transmitting coil which in turn activates the stimulating electrode. The neurostimulatory system can be used for relief of visceral and somatic pain as well as for controlling appetite in patients.
