Abstract

A method for remote and nonconnected interaction between an implant having an electrical motor and a transmitter/receiver inverter having an induction source having/connected to a power source for operating the electrical motor including creating modifications in an electromagnetic field by the transmitter/receiver inverter, and transmitting information in the form of binary data from the transmitter/receiver inverter to the implant; and a device for remote and nonconnected interaction with an implant having a transponder including an induction source having/connected to a power source, and means enabling the induction source to create modifications in an electromagnetic field generated in the device to transmit information in the form of binary data to the implant.

Claims

1. A method for remote and nonconnected interaction between an implant having an electrical motor and a transmitter/receiver inverter having an induction source having/connected to a power source for operating the electrical motor comprising:

creating modifications in an electromagnetic field by the transmitter/receiver inverter; and

transmitting information in the form of binary data from the transmitter/receiver inverter to the implant.

2. The method according to claim 1, wherein transmission of the information is in bits which are optionally delayed.

3. The method according to claim 1, further comprising transmitting information from the implant to the transmitter/receiver inverter.

4. The method according to claim 1, wherein the information pertains alternatively or cumulatively to:

a serial number of the implant;

a identification of a patient;

a date of initial operation;

a date of last intervention;

a number of interventions;

a state of the implant;

a history of content of interventions;

acknowledgments of receipt of transmissions; and

a confirmation of implementation of the action.

5. The method according to claim 4, wherein acknowledgments of receipt of transmissions are constituted of particular bits.

6. A device for remote and nonconnected interaction with an implant having a transponder comprising:

an induction source having/connected to a power source; and

means enabling the induction source to create modifications in an electromagnetic field generated in the device to transmit information in the form of binary data to the implant.

7. The device according to claim 6, wherein the means enabling creation of modifications in implementing the electromagnetic field comprises an inverter which interacts with a transmitter antenna in the transponder.

8. The device according to claim 7, wherein the antenna is coupled to a receiver.

9. The device according to claim 6, further comprising:

a microcontroller connected to a display; and

a command device capable of communicating with a computer functioning as interface.

a serial number of the implant;

identification of the patient;

a date of initial operation;

a date of the last intervention;

a number of interventions;

state of the implant;

a history of the content of interventions;

acknowledgments of receipt of transmissions; and

a confirmation of implementation of action.
