Abstract

Therapeutic system with implantable therapeutic unit (ITU) comprising control unit (CU), memory, telemetry unit connected (in)directly to CU for wireless bidirectional transmission of data to/from external device (ED) and detection unit for detecting physiological patient data or operational data. CU triggers outgoing data transmission (DT) from ITU to ED based on preselected internal events and establishes standby mode for reception on part of telemetry unit for receiving beginning (header) of incoming DT from ED to therapeutic unit exclusively within preselected response time window after DT from ITU to ED. System designed to add to incoming DT follow-up signaling data which signals an imminent follow-up examination, whereby CU also prompts sensor unit at preselected time point in response to receipt of follow-up signaling data to detect preselected physiological data required for follow-up examination or to detect operational data of therapeutic and store in memory and transmit with subsequent outgoing DT to ED.

Claims

1. A therapeutic system comprising:

an implantable therapeutic unit, comprising

a control unit;

a memory connected to the control unit;

a telemetry unit connected at least indirectly to the control unit for wireless bidirectional transmission of data to and from an external device;

a detection unit configured to detect physiological data of a patient or operational data of an implantable therapeutic unit;

wherein the control unit is configured to trigger an outgoing data transmission from the implantable therapeutic unit to the external device based on preselected therapeutic-device-internal events and establish a standby mode for reception on part of the telemetry unit to receive a beginning (header) of an incoming data transmission from the external device to the implantable therapeutic unit within a preselected response time window after the outgoing data transmission from the implantable therapeutic unit to the external device or within a reception time window at times preset in the implantable therapeutic unit;

wherein the therapeutic system is configured to add follow-up signaling data to the incoming data transmission, signaling an imminent follow-up examination;

wherein the control unit is also configured to prompt a sensor unit at a preselected point in time in response to receipt of the follow-up signaling data to detect detected data comprising preselected required physiological data or operational data of the implantable therapeutic unit for a follow-up examination and to store detected data in the memory and transmit the detected data together with a subsequent outgoing data transmission to the external device.

2. The therapeutic system according to claim 1, wherein the preselected point in time is immediately after receipt of the follow-up signaling data.

3. The therapeutic system according to claim 2, further comprising:

a service center configured to communicate bidirectionally with the external device for data communication with the implantable therapeutic unit;

wherein said service center has a date memory for storing a date for a coming follow-up examination;

wherein said service center is configured to determine a point in time for a preliminary examination which occurs a preselected amount of time before the date for the coming follow-up examination;

wherein said service center is configured to prompt the external device to generate an incoming message directed from the external device to the implantable therapeutic unit after receipt of an outgoing message originating from the implantable therapeutic unit after the point in time of the preliminary examination, said incoming message comprising the follow-up signaling data and wherein said incoming message is transmitted to the implantable therapeutic unit within the preselected response time window.

4. The therapeutic system according to claim 3, wherein the service center is designed to prompt the external device to generate the incoming message directed from the external device to the implantable therapeutic unit only after receipt of the outgoing message originating from the implantable therapeutic unit after the point in time of the preliminary examination, wherein said incoming message contains the follow-up signaling data, and to transmit said incoming message within the preselected response time window to the implantable therapeutic unit when a preselected resting period of time has elapsed since a prior transmission of signaling data to the implantable therapeutic unit.

5. The therapeutic system according to claim 1, wherein the implantable therapeutic unit has a time and date generator connected to the control unit, and wherein the control unit is configured in response to receipt of follow-up signaling data, to extract from the follow-up signaling data a date of a coming follow-up examination and to determine a point in time for a preliminary examination to occur a preselected amount of time before the date for the coming follow-up examination, and wherein said control unit is configured to prompt the sensor unit at the point in time of the preliminary examination as the preselected point in time to detect the preselected required physiological data or operational data for the coming follow-up examination.

6. The therapeutic system according to claim 5, wherein the therapeutic system comprises a service center which is configured to communicate bidirectionally with an external device for data communication with the implantable therapeutic unit and wherein said service center has a date memory for storing a date for an coming follow-up examination and wherein said service center is configured to prompt the external device to generate an incoming message directed from the external device to the implantable therapeutic unit after receipt of an outgoing message originating from the implantable therapeutic unit, said incoming message comprising the follow-up signaling data including the date of the coming follow-up examination and wherein said external device transmits said follow-up signaling data to the implantable therapeutic unit within the preselected response time window.

7. The therapeutic system according to claim 3, wherein the service center comprises, at least indirectly, an input unit for entering the date of an coming follow-up examination.

8. The therapeutic system according to claim 1, wherein the implantable therapeutic unit is designed to prompt the sensor unit to detect the preselected required physiological data or operational data of the implantable therapeutic unit for a follow-up examination and to store the detected data in the memory and to transmit the detected data with a subsequent outgoing data transmission to the external device only when more than a preselected dormant time has elapsed since a prior detection or transmission of data.

9. A therapeutic system comprising:

an implantable therapeutic unit, comprising

a control unit;

a memory connected to the control unit;

a telemetry unit connected at least indirectly to the control unit for wireless bidirectional transmission of data to and from an external device;

a detection unit configured to detect physiological data of a patient or operational data of an implantable therapeutic unit;

wherein the control unit is configured to trigger an outgoing data transmission from the implantable therapeutic unit to the external device based on preselected events internal to the implantable therapeutic unit and establish a standby mode for reception on part of the telemetry unit to receive a beginning (header) of an incoming data transmission from the external device to the implantable therapeutic unit within a preselected response time window after the outgoing data transmission from the implantable therapeutic unit to the external device or within a reception time window at times preset in the implantable therapeutic unit;

wherein the therapeutic system is configured to add follow-up signaling data to the incoming data transmission, signaling an imminent follow-up examination;

wherein the control unit is also configured to prompt a sensor unit at a preselected point in time to detect detected data comprising preselected required physiological data for a follow-up examination or operational data of the implantable therapeutic unit and to store detected data in the memory in response to the receipt of an incoming data transmission containing follow-up signaling data, and transmit the detected data to the external device together with a subsequent outgoing data transmission.
