Exercise triggered cardiovascular pressure measurement
First Claim
1. A method comprising:
- determining, by processing circuity of an implantable medical device implanted in a patient, that a triggering event has occurred based on statuses for a set of physiological parameters associated with the patient, the physiological parameters indicative of the patient engaging in a patient initiated physical activity;
generating, by trigger circuitry of the implantable medical device, a trigger output signal in response to the determination that the triggering event has occurred;
wirelessly transmitting, by a communication circuitry of the implantable medical device, the trigger output signal to a pressure sensing device implanted in a vessel of the patient;
triggering, based on receiving the trigger output signal at a communication circuitry of the pressure sensing device, the pressure sensing device to sense a cardiovascular pressure of the patient; and
transmitting, by the communication circuitry of the pressure sensing device, a wireless signal to the implantable medical device, the wireless signal comprising data corresponding to the sensed cardiovascular pressure of the patient; and
wherein determining that the triggering event has occurred based on at least one status for the set of physiological parameters associated with the patient further comprises;
determining, by a timer in the implantable medical device, if a minimum amount of time has elapsed since a last triggering event has occurred, andgenerating a trigger output signal only if the minimum amount of time has elapsed and only then in response to the determination that the triggering event has occurred based on the statuses for the set of physiological parameters associated with the patient.

13. An implantable medical device, comprising:
-
processing circuitry configured to receive input signals from one or more sensors, the input signals comprising signals generated in response to measured physiological parameters associated with a patient, and to determine a status for each of a set of input parameters based on the measured physiological parameters, the status for each of the set of input parameters indicative of whether or not current value for the input parameter satisfies a threshold value for that input parameter; trigger circuitry configured to automatically generate a trigger output signal based at least in part on a determination that the statuses of the input parameters are indicative of the patient engaging in a patient initiated physical activity; communication circuitry configured to receive the trigger output signal generated by the trigger circuitry, and to wirelessly transmit the trigger output signal to a pressure sensing device that is adapted to be implanted in a vessel of the cardiovascular system of the patient, the pressure sensing device configured to sense a cardiovascular pressure upon receipt of the trigger output signal; and a timer, the timer configured to provide a status indication that is indicative of whether a minimum time period has elapsed since the last occurrence of the trigger circuitry issuing a trigger output signal; the trigger circuitry configured to receive that status indication provided by the timer, and to only issue a trigger output signal if the status indication indicates that the minimum time period has elapsed since the last issuance of a trigger output signal. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
