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 controlling a gastric constriction ring with a control device lacking a physical connector between the control device and the ring, wherein the gastric constriction ring comprises an electrical motor and the control device comprises an induction source having a power source for operating the electrical motor, comprising:

a) transmitting displacement instructions for positioning the gastric constriction ring in the form of binary data to the gastric constriction ring by selectively interrupting an electromagnetic field generated by the induction source;

b) receiving end motor instructions from the gastric constriction ring;

c) querying the ring position to the gastric constriction ring;

d) receiving the ring position;

e) checking whether the ring position is correct; and

f) returning to a) if the ring position is not correct and turning off the control device if the ring position is correct.

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

3. The method according to claim 1, further comprising transmitting information from the gastric constriction ring to a transmitter/receiver inverter.

4. The method according to claim 1, wherein the binary data includes alternatively or cumulatively of:

a serial number of the gastric constriction ring;

identification of a patient;

a date of initial operation;

a date of last intervention;

a number of interventions;

a state of the gastric constriction ring;

a history of content of interventions;

acknowledgments of receipt of transmissions; and

a confirmation of implementation of an action.

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

6. The method according to claim 1 further comprising increasing the magnetic field to transmit power to the electric motor after the displacement instructions transmission (a);

and decreasing the magnetic field after receiving end motor instructions from the gastric constriction ring (b).
