Abstract: An IMD system receives a near field His bundle electrical signal produced by a patient's heart via a first sensing electrode vector and a far field cardiac electrical signal via a second sensing electrode vector different than the first sensing electrode vector. The IMD system generates His bundle pacing pulses delivered to the patient's heart via a His pacing electrode vector and determines a type of cardiac capture evoked by a His bundle pacing pulse.

Abstract: A transseptal catheter delivery system includes an elongate first tubular member and an elongate second tubular member receivable within the first tubular member. The first tubular member includes an adjustable portion adjacent a distal end. The second tubular member is adapted to receive an instrument to be placed in the left ventricle, and includes a curved portion adjacent its distal end in a relaxed state. The adjustable portion is deflectable toward the atrial septum to guide a puncturing tool and/or guide insertion of the second tubular member through a septal puncture into the left atrium. Within the left atrium, the curved portion is oriented toward the left ventricle to guide insertion of a guide wire, and subsequently the second tubular member, into the left ventricle. Methods of transvenously accessing a left ventricle are also provided.

Abstract: VfA cardiac therapy uses an implantable medical device or system. The implantable medical device includes a tissue-piercing electrode implanted in the basal and/or septal region of the left ventricular myocardium of the patient's heart from the triangle of Koch region of the right atrium through the right atrial endocardium and central fibrous body. The device may include a right atrial electrode, a right atrial motion detector, or both. The device may be implanted completely within the patient's heart or may use one or more leads to implant electrodes in the patient's heart. The device may be used to provide cardiac therapy, including single or multiple chamber pacing, atrioventricular synchronous pacing, asynchronous pacing, triggered pacing, cardiac resynchronization pacing, or tachycardia-related therapy. A separate medical device may be used to provide some functionality for cardiac therapy, such as sensing, pacing, or shock therapy.

Abstract: An implantable device system for delivering electrical stimulation pulses to a patient's body includes a pulse delivery device having a piezoelectric element that is enclosed by a housing and produces voltage signals delivered to the patient's body in response to receiving ultrasound energy. The pulse delivery device includes a circuit having a rate limiter configured to filter voltage signals produced by the piezoelectric element a rate faster than a maximum stimulation rate.

Abstract: A medical device includes a motion sensor for producing a motion signal including cardiac event signals. The medical device generates a ventricular pacing pulse upon expiration of a pacing interval. The medical device determines a synchrony metric from the motion signal after a delivered ventricular pacing pulse and adjusts the pacing interval based on the synchrony metric.

Abstract: An adapter configured to electrically connect a test device to an implantable medical lead comprises a rotational electrical coupling. The rotational electrical coupling is configured to electrically connect a lead electrical connector to an adapter electrical connector. The rotational electrical coupling comprises a first conductive component configured to be electrically connected to the lead electrical connector and rotatable with a proximal portion of the implantable medical lead, and a second conductive component electrically connected to the first conductive component and the adapter electrical connector. The second conductive component may be rotationally fixed. The first and second conductive components may comprise graphite or another soft metal.

Abstract: An implantable medical device system receives a cardiac electrical signal produced by a patient's heart and comprising atrial P-waves and delivers a His bundle pacing pulse to the patient's heart via a His pacing electrode vector. The system determines a timing of a sensed atrial P-wave relative to the His bundle pacing pulse and determines a type of capture of the His bundle pacing pulse in response to the determined timing of the atrial P-wave.

Abstract: Novel tools and techniques are provided for presenting patient information to a user. In some embodiments, a computer system may: receive device data associated with one or more devices configured to perform a cardiac shunting procedure to change a cardiac blood flow pattern to improve cardiac blood flow efficiency or cardiac pumping efficiency; receive one or more imaging data associated with one or more imaging devices configured to generate images of one or more internal portions of the patient; analyze the device data and the imaging data; map the device data and the imaging data to a multi-dimensional representation of the one or more internal portions of the patient; generate one or more image-based outputs based at least in part on the mapping; and present, using a user experience (“UX”) device, the generated one or more image-based outputs.
