Abstract
An electromedical implant (1), in particular a cardiac pacemaker, comprising a telemetry device at least for the communication of data to an external apparatus (2), which includes a transmitting device with a transmitter, wherein the transmitter includes an oscillator comprising a first transistor (58) and a resonator (60), and a second transistor (59) forming a buffer stage and an antenna driver.
Claims8
An electromedical implant implantable in a patient comprising:
- a telemetry device at least for the communication of patient data to an external patient data processing apparatus, the telemetry device including:
- a transmitting device having a transmitter, the transmitter including:
- an oscillator having a first transistor and a resonator;
- a second transistor, coupled to the oscillator as a buffer stage and an antenna driver for transmitting the patient data from the electromedical implant to the external patient data processing apparatus;
- and
- a capacitance diode, wherein the capacitance diode is arranged in series with the resonator for frequency modulated transmission of patient data.
