Abstract: A first embodiment of the implantable real-time oximeter of the present invention is attached around a blood vessel near the site of a likely stroke to monitor large and medium size cerebral arteries. Another embodiment of the implantable real-time oximeter can be passed within cerebral blood vessels to monitor the oxygenation status of the surrounding cerebral tissues. When used within cerebral blood vessels, the emitter and detector are coplanar and contained in a small area, for example, 50-120 ?m.

Abstract: There is provided an implantable pressure monitor having a fluid sack in contact with a body part of a patient where the fluid sack is retained to the body part by a pressure monitor housing that may have various attachment means. The fluid sack is filled with a liquid such as silicone oil. The pressure monitor housing has an opening that provides access to a fistula with a fluid valve that terminates through the fluid sack. A fiber optic pressure sensor is in contact with the liquid in the fluid sack by way of the fistula and fluid valve. In some embodiments of the present invention, an electronics module is incorporated with the implantable pressure monitor to provide telemetry, power, and the like.

Abstract: A deep brain magnetic stimulator is disclosed that is placed within a vessel of the body to provide targeted location specific application of a magnetic field within the brain. The deep brain magnetic stimulator has a stimulation coil affixed to an expandable device core where the device core has a lumen to allow the passage of blood. A source of electrical energy is provided as well as related control circuitry to govern the activation of the stimulation coil and also govern such parameters as magnetic field strength, duration, waveform, and the like.

Abstract: A first embodiment of an oximetry probe is attached around a blood vessel near the site of a likely stroke. That will be useful to monitor large and medium size cerebral arteries. Another type of pulse oximeter can be passed within cerebral blood vessels to monitor the oxygenation status of the surrounding cerebral tissues. In that version, the emitter and detector are coplanar and contained in a small area, e.g., 50-12 ?m.
