Abstract: An implantable medical device includes a rechargeable battery and a battery recharging assembly. The battery recharging assembly includes an energy receiver for capturing energy from an externally applied charging field, a battery charging circuit that is operably coupled to the rechargeable battery for recharging the rechargeable battery, and a demodulator that is operably coupled to the energy receiver and the battery charging circuit. The demodulator demodulates the energy captured by the energy receiver and delivers demodulated energy to the battery charging circuit to be used to charge the rechargeable battery. The IMD includes a controller that is configured to control operation of at least part of the IMD.

Abstract: Systems and methods for providing rate responsive pacing therapy to a heart of a patient. One example method for providing rate responsive pacing therapy includes sensing cardiac electrical data with a leadless cardiac pacemaker (LCP) that is implanted within or proximate the heart. From this location, the LCP may provide pacing therapy to the heart based at least in part on the sensed cardiac electrical data. An implantable medical device located remotely from the heart may sense patient activity, and may wirelessly communicate patient activity data from the implantable medical device to the LCP, sometimes using conducted communication. The LCP may be then determine an adjustment to the provided pacing therapy (e.g. adjust the pacing rate) based at least in part on the received patient activity data signal.

Abstract: An implantable medical device includes operational circuitry, such as a therapy circuit. The implantable medical device also includes a power source configured to deliver energy to the operational circuitry, and a deactivation element configured to disable the therapy circuit. A power manager is configured to detect an end-of-life condition of the power source and, in response to detecting the end-of-life condition, cause the deactivation element to reversibly disable the therapy circuit.

Abstract: An implantable medical device (IMD) is configured with a pressure sensor. The IMD includes a housing, a pressure sensor and a fluid filled cavity. The housing has a diaphragm that is exposed to the environment outside of the housing. The pressure sensor has a pressure sensor diaphragm that is responsive to a pressure applied to the pressure sensor diaphragm and provides a pressure sensor output signal that is representative of the pressure applied to the pressure sensor diaphragm. The fluid filled cavity is in fluid communication with both the diaphragm of the housing and the pressure sensor diaphragm of the pressure sensor. The fluid filled cavity is configured to communicate a measure related to the pressure applied by the environment to the diaphragm of the housing to the pressure sensor diaphragm of the pressure sensor.

Abstract: An implantable medical device (IMD) may include a sensor for providing a sensor output signal and a sense channel configured to receive the sensor output signal from the sensor. The sense channel may be configured to process the sensor output signal and output a sense channel output signal. The sense channel may have an adjustable performance level, wherein for a higher performance level the sense channel consumes more power than for a lower performance level. A controller may be configured to adjust the performance level of the sense channel to achieve more performance and more power consumption when a higher degree of sense channel performance is desired and to achieve less performance and less power consumption when a higher degree of performance is not desired.

Abstract: Methods and devices for configuring the use of a motion sensor in an implantable cardiac device. The electrical signals of the patient's heart are observed and may be correlated to the physical motion of the heart as detected by the motion sensor of the implantable cardiac device in order to facilitate temporal configuration of motion sensor data collection that avoids detecting cardiac motion in favor of overall motion of the patient.

Abstract: An implantable cardiac monitor (ICM) may be configured to be deployed subcutaneous, submuscular, or substernal at a position that enables the ICM to detect cardiac activity. In some cases, the ICM includes a housing that includes a body portion and a tail portion. A first electrode may be disposed adjacent a first end of the body portion, a second electrode may be disposed adjacent a second end of the body portion and a third electrode may be disposed adjacent a tail end of the tail portion. A controller may be disposed within the housing and may be operably coupled to the first electrode, the second electrode and the third electrode. The controller may be configured to select a pair of the first electrode, the second electrode and the third electrode to use for sensing cardiac electrical activity and to communicate information about the sensed activity to a second medical device.

Abstract: A leadless cardiac pacemaker (LCP) is configured to sense cardiac activity and to pace a patient's heart and is disposable within a ventricle of the patient's heart. The LCP MAY include a housing, a first electrode and a second electrode that are secured relative to the housing and are spaced apart. A controller is disposed within the housing and is operably coupled to the first electrode and the second electrode such that the controller is capable of receiving, via the first electrode and the second electrode, electrical cardiac signals of the heart. The LCP may include a pressure sensor and/or an accelerometer. The controller may determine a pace time within a cardiac cycle based at least in part upon an indication of metabolic demand.

Abstract: Systems and methods for conducted communication are described. In one embodiment, a method of communicating with a medical device implanted within a patient comprises receiving, at a medical device via electrodes connected to the patient, a conducted communication signal, wherein the conducted communication signal comprises a signal component and a noise component. The method may further comprise adjusting, by the medical device, a receive threshold based at least in part on an amplitude of the received conducted communication signal so as to reduce an amplitude of the noise component of the conducted communication signal.
