An overvoltage protection element, provided as a component of a medical device () used on or in a human or animal body, reduces power absorption upon application of an external overvoltage signal having chronological rising and/or decay characteristic at an interface () of the medical device (). The overvoltage protection element has reshaping means () which convert the external overvoltage signal at the interface () into an internal voltage pulse, and limiting means () which limit a voltage drop on at least one electronic component of the medical device to a predetermined limiting value.

Overvoltage protection element

The invention relates to a therapy system and a therapy device having at least one data communication interface which can operate in various data transmission modes and cooperates with a data communication control unit. The data communication interface can change from one data transmission mode to another without interruption of an existing data link. The change is controlled by the data communication control unit as a function of predefined selection criteria.

Electric therapy system and therapy device

A method of making a wireless communication connection between a patient device and an electromedical implant as communication partners is disclosed, wherein a transmitting unit of the patient device is continually switched on and off, so that the transmitting unit is alternately in an activity phase and an activity pause and during its activity pause at least once sends a recognition signal and wherein a receiving unit of the electromedical implant is continually switched on and off so that the receiving unit is alternately in an activity phase and an activity pause and during its activity phase checks whether the transmitting unit is just then in its activity phase and sends a recognition signal, wherein switching on and off of the receiving unit is so effected that an activity phase and an activity pause of the receiving unit together give an overall duration which differs from the overall duration of an activity phase and an activity pause of the transmitting unit so that within a foreseeable period of time the activity phases of the transmitting unit and the receiving unit overlap and a wireless communication connection between the two communication partners occurs.
