Abstract

An electronic medical system is described. The system comprises an external RF power transmitter configured to emit a first power signal via an electromagnetic coupling, said RF power transmitter being configured to emit said first energy signal with a power no greater than 1 W. The system further comprises an implantable medical device comprising: at least one receiver antenna configured to receive said first energy signal via an electromagnetic coupling; an RF power receiver module configured to extract a second energy signal having a power of at least 1 milliwatts and to be powered by said second energy signal; a power actuator module, operatively connected to the RF power receiver module, powered by said second energy signal. The power actuator module is configured to deliver a medical treatment to at least a target tissue of a patient on the basis of a control signal generated by the RF power receiver module.

Claims

1. An electronic medical system, comprising:

an external RF power transmitter configured to emit a first energy signal via an electromagnetic coupling, said external RF power transmitter being configured to emit said first energy signal with a power no greater than 1 W; and

an implantable medical device comprising;

at least one receiver antenna configured to receive said first energy signal via an electromagnetic coupling, the at least one receiver antenna is a directional antenna;

an RF power receiver module operatively connected to the at least one receiver antenna, the RF power receiver module being configured to extract a second energy signal having a power of at least 1 milliwatts, the RF power receiver module being powered by said second energy signal, the RF power receiver module being configured to generate a control signal; and

a power actuator module, operatively connected to the RF power receiver module, powered by said second energy signal, the power actuator module being configured to receive said control signal, the power actuator module being configured to deliver a medical treatment to at least a target tissue of a patient on the basis of said control signal.

2. The system of claim 1, wherein the at least one receiver antenna is of a subcutaneous type.

3. The system of claim 2, wherein the target tissue comprises a skin layer and a fat layer, the at least one receiver antenna is placed in the fat layer of the target tissue.

4. The system of claim 3, wherein the at least one receiver antenna is coated in a bio-compatible material.

5. The system of claim 4, wherein the bio-compatible material is a low electrical conductivity material.
