Abstract: The invention relates to methods by which radio signals can be transmitted to, and received by, a radio receiver such that the receiver consumes very little power from a battery or energy source. The invention also relates to methods by which radio signals, modulated with data information, can be produced by a transmitter that consumes very little power. The invention is applicable not only to medical implants, but any application requiring a radio receiver to operate with very low power consumption.

Abstract: A patient device (PD) for wireless data communication with an implant. The PD can be at least in an unpaired state or a paired state. In the paired state the PD is paired to a specific implant specified by an implant's identification code (IIC). The IIC is stored in PD memory. Automatic pairing of the PD to a specific implant is performed upon receiving an incoming data packet containing an IIC when the PD is in its unpaired state with no valid IIC stored in memory. Thus, the PD is tentatively paired to an implant identified by the IIC contained in the incoming data packet by storing the IIC in the memory. Tentative pairing is cancelled if no further communication occurs within a predetermined period of time. A soft paired state is entered if further data communication does occur.

Abstract: A device for maintaining or reestablishing a natural heart rhythm by generating an electrical stimulation signal. In particular a device in the form of an implantable heart pacemaker that displays at least one sensor arranged inside the patient's body for picking up a body-specific signal containing information concerning demand for heart performance, or another magnitude relevant to the heart. The device is characterized by the fact that connected downstream to the sensor is a processing unit that obtains from the measurement signal a body-specific rhythm signal whose periodicity is equal to or greater than the periodicity of the breathing activity, and thus lies above the periodicity of the heart activity, whereby the body-specific rhythm signal forms a control signal that influences the stimulation signal.

Abstract: Device for maintaining or restoring a natural heart rhythm through the generation of an electrical stimulation signal, in particular in the form of an implantable heart pacemaker, which device shows two sensors arranged inside the body of the patient for picking up a body-specific signal that contains information concerning the demand for heart performance or another magnitude relevant to the heart. Connected to the downstream side of the sensors is a processing unit that obtains, from the temporal difference of a body-specific signal received one after another at both sensors, a body-specific time-delay signal, which represents the length of the determined time delay. The body-specific time-delay signal forms at least indirectly a control signal that influences the point in time and/or the time sequence of the stimulation signal.
