Abstract: Systems and methods to determine presence of an analyte using an implantable medical device are disclosed. In an embodiment, a medical system includes an implantable medical device, a light source, an optical sensor and a processor. The implantable medical device includes an indicator tag, which is responsive to an analyte. The light source is configured to emit light onto the indicator tag, where the emitted light comprises at least one wavelength of light, and where the indicator tag emanates light, in response to the emitted light, that corresponds to whether the indicator tag is exposed the analyte. The optical sensor is configured to receive at least a portion of the emanated light, which includes at least one wavelength of light. And, the processor is configured to determine whether the indicator tag is exposed to the analyte based on the received light.

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: A cardiac rhythm management system includes a first implantable device such as a defibrillator and a second implantable device such as a leadless cardiac pacemaker. A programmer is configured to receive and display heart data emanating from the implantable defibrillator and from the leadless cardiac pacemaker. The heart data emanating from the leadless cardiac pacemaker is displayed in temporal alignment with the heart data emanating from the implantable defibrillator.

Abstract: Methods, systems and devices for providing cardiac resynchronization therapy (CRT) to a patient using a leadless cardiac pacemaker (LCP) and an extracardiac device (ED). The system is configured to identify atrial events to use as timing markers for the LCP to deliver CRT, and further to determine whether the timing markers are incorrectly sensed and to make adjustment or call for re-initialization as needed.

Abstract: Systems, devices, and methods for pacing a heart of a patient are disclosed. In some embodiments, a method for pacing a patient's heart may include determining a posture of the patient and determining if the determined posture corresponds to a predetermined sleep posture. If the determined posture correspond to the predetermined sleep posture, the method may further comprise determining a respiration phase of the patient and pacing the patient's heart at a pacing rate that is modulated based on the determined respiration phase of the patient. If the determined posture does not correspond to the predetermined sleep posture, the method may pace the patient's heart at a pacing rate that is not dependent on the respiration phase of the patient.

Abstract: A ventricularly implantable medical device that includes a sensing module that is configured to identify a search window of time within a cardiac cycle to search for an atrial artifact. Control circuitry in the ventricular implantable medical device is configured to deliver a ventricular pacing therapy to a patient's heart, wherein the ventricular pacing therapy is time dependent, at least in part, on an atrial event identified in the search window of time.
