Patent ID: 8423133

Claim:
A medical device comprising: a unit configured to detect electromagnetic interference, having at least one sensor and/or indicator for electromagnetic interference fields; at least one switching device coupled with said unit configured to detect electromagnetic interference; at least one electrode coupled with said at least one switching device; at least one control unit coupled with the at least one electrode wherein said at least one control unit is further coupled with said unit configured to detect electromagnetic interference; wherein the at least one switching device comprises one or more individual switching elements, and is configured to be switched in series with one or more electromagnetic interference capacitors, or the at least one switching device is configured to be switched in parallel with one or more electromagnetic interference capacitors; wherein the at least one switching device comprising one or more individual switching elements is configured so that the electromagnetic interference capacitors are reversed in polarity using one or more frequencies which are modified, and/or predetermined, and/or automatically matched to measured field intensity parameters, wherein a polarity reversal is carried out only for specific field parameters detected by the unit, or wherein a polarity reversal is carried out continuously; and, wherein the at least one electrode is configured to contact bodily tissue which enables detection of electromagnetic interference fields by said unit and wherein said at least one switching device is configured to automatically modify an input characteristic of the at least one electrode in such a way that influences of the electromagnetic interference fields to said medical device are minimized.
