USPTO Applicaton #: #20100100010
Inventors: Emad Andarawis Andarawis, Ertugrul Berkcan


The Patent Description & Claims data below is from USPTO Patent Application 20100100010, Implantable device system.

BACKGROUND

- Top of Page


The invention relates generally to implantable devices, and more specifically to remotely interrogated implantable devices.

Certain medical conditions of the human body are controlled and/or corrected via a mechanical device implanted in the body, as opposed to a chemical “drug” route. Medical treatment of such conditions using a mechanical device can avoid possible side effects due to the ingestion of drugs.

Such devices are generally implanted within the human body close to the area where the therapeutic/corrective action is required. The overall management (monitoring and manipulation) of the state of operation of such traditionally available devices has required complicated procedures. Faulty execution of the complicated procedures can expose the patient to an infection or other medical issues. In addition, on-going post implantation management of such traditional devices usually requires direct and regular supervision by a qualified medical doctor, which limits the set of people who can derive benefit from such systems in a sustainable and cost-effective manner.

In addition, currently available implantable systems support a limited number of operation states, which limits the number of bodily conditions that can be addressed accurately. Further, most currently available implantable systems are based on invasive methods of interrogating the device such as puncturing the living tissue using a needle.

An implantable device that addresses one or more of the above drawbacks of traditionally available implantable systems would therefore be highly desirable.

BRIEF DESCRIPTION

Embodiments of the invention are directed towards an implantable device system and a method of operating the implantable device system.

An implantable device system in accordance with an embodiment of the invention includes a first energy transceiver system, a second energy transceiver system at least partially implanted within an organic tissue and capable of being interrogated by the first energy transceiver system, and a sensing system. A state of the sensing system is available at the second energy transceiver system.

An implantable device system array in accordance with an embodiment of the invention includes a plurality of transceiver systems. Each of the transceiver systems includes a first energy transceiver system, a second energy transceiver system at least partially implanted within an organic tissue and capable of being interrogated by the first energy transceiver system, and a sensing system capable of performing a measurement operation of a physical parameter. A state of the sensing system is available at the second energy transceiver system. Each of the plurality of transceiver systems is capable of independently communicating with any or all other transceiver systems of the plurality of transceiver systems.

A method of monitoring a physical parameter in accordance with an embodiment of the invention includes (a) interrogation of a second transceiver system, via electromagnetic energy, by a first transceiver system, (b) using the electromagnetic energy within the second transceiver system to perform a physical parameter measurement operation, (c) transmitting a result of the physical parameter measurement operation from the second transceiver system to the first transceiver system, and (d) optionally independently repeating steps (a), (b), or (c). The second transceiver system is at least partially implanted within an organic tissue and is capable of communication with the first transceiver system.

These and other advantages and features will be more readily understood from the following detailed description of preferred embodiments of the invention that is provided in connection with the accompanying drawings.
