Abstract

Power saving communication techniques for communicating in a medical device system. One example medical device system may be for delivering electrical stimulation therapy to a heart of a patient, and may include a first implantable medical device implanted in a first chamber of the heart and configured to determine one or more parameters, a medical device physically spaced from and communicatively coupled to the first implantable medical device, the medical device configured to deliver electrical stimulation therapy to the heart of the patient, wherein the first implantable medical device is further configured to: compare a value of a first determined parameter to a first threshold; if the value of the first determined parameter passed the first threshold, communicate a first indication to the medical device; and if the value of the first determined parameter has not passed the first threshold, not communicating the first indication to the medical device.

Dependent claims

A method of communication information from a first medical device to a second medical device, the method comprising:

communicating a first threshold corresponding to a first physiological parameter of a patient from a first medical device to a second medical device, wherein the second medical device comprises a leadless device that is configured to be implanted within the patient, the first physiological parameter is detected based at least in part on one or more of a cardiac electrical signal, a heart sound signal, a blood pressure signal, a blood oxygen signal, and a motion signal;
monitoring a value of the first physiological parameter of the patient with the second medical device;
determining if the value of the first physiological parameter of the patient has passed the first threshold;
if the value of the first physiological parameter of the patient has passed the first threshold, communicating a first indication from the second medical device to the first medical device;
and
if the value of the first physiological parameter of the patient has not passed the first threshold, not communicating the first indication from the second medical device to the first medical device.

A method of reducing communication transmissions in a medical device system, the method comprising:

monitoring a parameter with an implantable leadless medical device;
with the implantable leadless medical device, comparing the monitored parameter to a first threshold and determining if the monitored parameter has passed the first threshold;
if the monitored parameter has passed the first threshold, communicating a first indication from the implantable leadless medical device to another medical device;
if the monitored parameter has not passed the first threshold, not communicating the first indication from the implantable leadless medical device to the another implantable medical device;
and
if the monitored parameter has passed the first threshold, begin to compare the monitored parameter to a second threshold and determining if the monitored parameter has passed the second threshold, wherein the second threshold is further past the first threshold;
and
if the monitored parameter has passed the second threshold, communicating a second indication from the implantable leadless medical device to the another implantable medical device;
and
if the monitored parameter has not passed the second threshold, not communicating the second indication from the implantable leadless medical device to the another implantable medical device.
