A method and apparatus for data transmission between an electromedical implant having a first transmitter/receiver unit, such as a cardiological implant, and an associated external apparatus having a second transmitter/receiver unit. Data transmission begins with a triggering signal which is sent by the first transmitter/receiver unit in normal operation in predeterminable first intervals. Reception readiness of the first transmitter/receiver unit is maintained after emission of the triggering signal for a second time interval which is shorter than the first time interval.

Method and apparatus for data transmission between an electromedical implant and an external apparatus

An electromedical implant comprising a telemetry device for the exchange of data with an external apparatus is provided. The telemetry device comprising a transmitting device and a receiving device, wherein a separate energy storage means is provided for each of the transmitting device and the receiving device. A method of using an electromedical implant comprising a telemetry device for the exchange of data is also provided.

Electromedical implant

An implantable cardiac pacemaker ( ) comprising a control device ( ) including a position detector connected to a movement sensor, wherein the position detector has a classification device ( ) for recognizing short movements. Preferably the position detector has a memory device ( ).

Cardiac pacemaker with position detector

A method of after-care in relation to patients with at least one electromedical implant. Data is transmitted from the implant to an external apparatus providing information for an examining clinician on the occasion of an after-care examination of the patient in an after-care arrangement. In an after-care interrogation up-to-date available data of the implant are interrogated and sent for output to corresponding output means, the data interrogation operation being effected prior to the after-care examination automatically after the patient enters an interrogation region of the after-care arrangement.

Method of data interrogation in implant after-care

Apparatus for the transmission of at least first data from an electronic device ( ), in particular an electromedical implant such as a cardiac pacemaker, to a monitoring arrangement ( ), including at least a first interface device ( ), with at least one input unit for the first data, a control device ( ) connected to the first interface device ( ) and a mobile radio device ( ) connected to the control device at least for the transmission of the first data to the monitoring arrangement ( ) by way of a telecommunication network which is at least in part in the form of a mobile radio network, wherein there is provided at least one second interface device ( ) connected to the control device ( ) for connecting the control device to a fixed-line telecommunication network.

Apparatus for the transmission of data in particular from an electromedical implant

A patient monitoring system ( ) is provided with at least one body sensor ( ) for measuring a physiological parameter, as well as with a body signal processing unit ( ) connected downstream from the former and/or a therapy device ( ) designed to act on the patient (P), and a mobile radiotelephone end unit ( ) operable in a cellular mobile radiotelephone network ( B) for transmitting data from the body signal processing unit or the therapy device to a central monitoring station ( C) and/or from the central monitoring station to the therapy device. A base station coordinate memory unit ( ) and a locator unit ( through ) connected to the former serves for the rough determination of the location of the patient based on location information obtained from the current base station connection of the mobile radiotelephone end unit in the mobile radiotelephone network. For the fine position determination, a direction-finding transmitter ( ) that sends out a direction-finding signal is provided in the mobile radiotelephone end unit ( ). A separate direction-finding device ( ) serves for the fine tracking of the direction-finding signal.

System for patient monitoring

An electromedical implant ( ), in particular a cardiac pacemaker, comprising a telemetry device at least for the communication of data to an external apparatus ( ), which includes a transmitting device with a transmitter, wherein the transmitter includes an oscillator comprising a first transistor ( ) and a resonator ( ), and a second transistor ( ) forming a buffer stage and an antenna driver.

Transmitter of the telemetry device of an implant

A method of monitoring patients with at least one electromedical implant, in which at least one first data transmission is effected between the implant provided with a first transmitting/receiving device and at least one external apparatus provided with a second transmitting/receiving device. At least first data are transmitted from the implant to the external apparatus and at least one second data transmission is effected between the external apparatus and at least one central storage arrangement for the storage of first data, by a telecommunication connection which is at least partially made by way of a mobile radio network. The transmission at least of the first data to the central storage arrangement is effected by way of the portion, formed by the mobile radio network, of the telecommunication connection in the form of at least one SM-string (Short Message String).

Method of data transmission in implant monitoring

An electromedical implant ( ), in particular a cardiac pacemaker, having a close-range telemetry device for data exchange with an external apparatus ( ), which includes at least a close-range antenna ( ) and a close-range transmitter/receiver unit with a close-range transmitter ( ), a telemetry unit ( ) connected thereto and an antenna interface device ( ) which is connected to the telemetry unit ( ) and by way of which the close-range antenna ( ) is connected to the close-range transmitter/receiver unit, wherein there is provided a long-range transmitter ( ) connected to the telemetry unit ( ) to provide a long-range telemetry device.

Implant with close and long-range telemetry

A rate-adaptive pacemaker includes an impedance measuring device for measuring a waveform over time of the intracardial impedance over at least a predetermined portion of one cardiac cycle. An impedance processing device obtains an impedance value from the waveform. A rate determining device is connected downstream of the impedance processing device, and controlled by a sequence controller, determines the adaptive stimulation rate (HR) using the impedance value. The impedance processing device has an integrator stage for determining the time integral of the impedance waveform over the predetermined portion of the cardiac cycle as the primary impedance value.
