Abstract: IMD devices and treatment methods are discussed and disclosed. An IMD having a lead adapted for placement in an internal thoracic vein (ITV) of a patient may be employed to facilitate atrial sensing. Devices may be used to communicate with one another, such communication configured to allow pacing therapy to a heart of a patient.

Abstract: An implantable medical device (IMD) that includes a housing, a first electrode secured relative to the housing, a second electrode secured relative to the housing, and a gyroscope secured relative to the housing. The IMD may include circuitry in the housing in communication with the first electrode, the second electrode, and the gyroscope. The circuitry may be configured to determine and store a plurality of torsion data measurements, from which a representation of a twist profile may be determined.

Abstract: A ventricular implantable medical device that is configured to detect an atrial timing fiducial from the ventricle. The ventricular implantable medical is configured to deliver a ventricular pacing therapy to the ventricle based on the detected atrial timing fiducial. If the ventricular implantable medical device temporarily fails to detect atrial activity because of noise, posture, patient activity or for any other reason, an atrial implantable medical device may be configured to communicate atrial events to the ventricular implantable medical device and the ventricular implantable medical device may synchronize the ventricular pacing therapy with the atrium activity based on those communications.

Abstract: A system for sensing electrical cardiac activity and for providing therapy to a patient's heart. The system may include a first implantable device implanted within a patient and a second implantable device implanted near or within the heart of the patient. In some cases, the first implantable device may at least partially power the second implantable device by periodically recharging a rechargeable battery or other power source within the second implantable device. In some cases, the first implantable device may at least partially power the second implantable device by periodically, intermittently or continuously transmitting energy that may be stored by a battery, capacitor or other power storage device within the second implantable device.

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: Implantable medical devices (IMD), such as but not limited to leadless cardiac pacemakers (LCP), neuro-stimulators (NS), and/or implantable monitors (IM), may be configured to communicate using more than one mode of communication and/or more than one communication vector. In some cases, the implantable medical device may be configured to switch between communication modes, vectors, and/or communication paths, which may help improve communication reliability and/or communication speed between devices.

Abstract: Implantable medical device (IMD) such as leadless cardiac pacemakers may include a rechargeable power source. In some cases, the IMD may include a plurality of receiving coils that may capture a non-radiative near-field energy and then convert the near-field energy into electrical energy that may be used to recharge the rechargeable power source. Accordingly, since the rechargeable power source does not have to maintain sufficient energy stores in a single charge for the entire expected life of the IMD, the power source itself and thus the IMD, may be made smaller while still meeting device longevity expectations.

Abstract: Systems and methods for monitoring patients with cardiac diseases are described. A system may include an accelerometer sensor for sensing an epicardial or endocardial acceleration (EA) signal. The accelerometer may be included in a leadless or a lead-based medical device. The system may additionally include a companion device in communication with the medical device via a wireless communication link. The companion device may sense a cardiac signal such as a heart sound signal, and may use the cardiac signal and the EA signal transmitted from the medical device to generate a diastolic function indicator indicating the diastolic function of the heart. The system may provide the diastolic function indicator to a user or a process, or to detect worsening of heart failure based on the diastolic function indicator.

Abstract: An implantable medical device (IMD) is configured with a pressure sensor. The IMD includes a housing and a diaphragm that is exposed to the environment outside of the housing. The diaphragm is configured to transmit a pressure from the environment outside of the housing to a piezoelectric membrane. In response, the piezoelectric membrane generates a voltage and/or a current, which is representative of a pressure change applied to the housing diaphragm. In some cases, only changes in pressure over time are used, not absolute or gauge pressures.
