Abstract: An implantable medical device for implantation into a patient may include a housing, a pulse generation circuit disposed at least partially within the housing, a plurality of electrodes electrically coupled to the pulse generation circuit, the plurality of electrodes being exposed external to the housing, and a controller operatively coupled to the pulse generation circuit. The controller may be configured to command the pulse generation circuit to deliver a phasic conducted communication pulse via at least two of the plurality of electrodes. Additionally, the phasic conducted communication pulse may comprise a first phase having a first polarity followed by a second phase having an opposite second polarity, wherein the second phase may have a duration of less than 60 microseconds, and wherein the first phase having may have a duration of between five percent and eighty percent of the duration of the second phase.

Abstract: Implantable medical devices (IMD), such as but not limited to leadless cardiac pacemakers (LCP), subcutaneous implantable cardioverter defibrillators (SICD), transvenous implantable cardioverter defibrillators, neuro-stimulators (NS), implantable monitors (IM), may be configured to communicate with each other. In some cases, a first IMD may transmit instructions to a second IMD. In order to improve the chances of a successfully received transmission, the first IMD may transmit the instructions several times during a particular time frame, such as during a single heartbeat. If the second IMD receives the message more than once, the second IMD recognizes that the messages were redundant and acts accordingly.

Abstract: An implantable medical device (IMD) may be deployed within a patient's right atrium at a location near a right atrial appendage of the patient's heart in order to pace the patient's heart and/or to sense electrical activity within the patient's heart. In some cases, an IMD may be implanted within the right atrial appendage. The IMD may include an expandable anchoring mechanism configured to secure the IMD in place.

Abstract: Systems and methods for conducted communication are described. In one embodiment, a method for communicating with implantable medical devices may comprise sensing, by a first medical device, a noise signal delivered into a patient's body by a second medical device and delivering, by the first medical device, a cancelling signal into the patient's body. In at least some additional embodiments the method may further comprise, while delivering the cancelling signal into the patient's body, delivering a conducted communication signal into the patient's body for reception by a second medical device.

Abstract: A leadless cardiac pacemaker (LCP) that is configured for atrial placement may include a housing, two or more electrodes and a controller that is disposed within the housing and that is operably coupled to the two or more electrodes. The controller may be configured to sense activation of the atrium of the patient's heart via two or more of the electrodes and to deliver pacing therapy via two or more of the electrodes to a ventricle of the patient's heart by pacing the bundle of His in the patient's atrioventricular septum.

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: 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.
