Implanted apparatus disabling switching regulator operation to allow radio frequency signal reception

An apparatus for implantation in a living organism and for communication with an external device by radio frequency transmission of a given level, comprising:

• a voltage converter including a switching regulator, which switching regulator in turn includes a coil for storing energy during operation of said switching regulator, such that when said switching regulator is operating, the coil produces certain levels of radio frequency signals;
• a radio transmission receiver having a defined sensitivity level for receiving radio frequency transmissions form the external device, wherein the level of the radio frequency signals from the regulator exceed the defined sensitivity level of the receiver, thereby interfering with said reception of the transmissions from the external device when said voltage converter is operating;
• and
• means for periodically disabling operation of said switching regulator for a predetermined interval and enabling the receiver to communicate with the external device during said interval.
