Wireless communication system for implamtable medical devices
First Claim
1. Medical communication system comprising an extracorporeal external communication module (2) and an implantable internal communication module (4) adapted to perform communication between each other, said internal communication module comprising energy receiving and supplying means (6) arranged to supply energy to said internal communication module, wherein said energy receiving and supplying means wirelessly can receive energy (22) from an energy generating and transferring means (12) in said external communication module, characterized in that said external communication module (2) further comprises a signal analysing means (14) that analyses a communication signal (26) received from the internal communication module (4) and determines a measure of the quality of the received communication signal as such and if said measure does not fulfill a predetermined criterion related to the communication signal the amount of energy transferred from the energy generating and transferring means (12) to the energy receiving and supplying means (6) is changed according to predetermined energy transferring rules.

Abstract
A medical communication system has an external communication module for extracorporeal use relative to a patient, and an internal communication module adapted for implantation in the patient. The external communication module has a transmitter which transmits energy to the internal communication module, which has a receiver that receives the energy and supplies it to power-consuming components in the internal communication module. The internal communication module has a transmitter which transmits a communication signal to a receiver in the external communication module. The received communication signal is analyzed in the external communication module to determine a measure of the quality of the communication signal. Dependent on whether the measure of the quality if the communication signal satisfies predetermined criterion, the transmitted energy is altered according to predetermined energy transferring rules.

11. Extracorporeal external communication module (2) adapted to perform communication with an implantable internal communication module (4) arranged to be connectable to or comprised in an implantable medical device, characterized in that said external module comprises a signal analysing means (14) that analyses a communication signal (26) received from the internal communication module and determines a measure of the quality of the received communication signal as such and if said measure of quality does not fulfill a predetermined criterion related to the communication signal the external communication module changes the amount of energy transferred from an energy generating and transferring means (12) comprised in said external communication module to the internal communication module, for energising said internal module, according to predetermined energy transferring rules.
