Abstract: In a medical device system, a computer apparatus is configured to receive body surface electrical signals from an electrode apparatus including multiple external electrodes. The computing apparatus generates electrical dyssynchrony data from the body surface electrical signals during delivery of His bundle pacing pulses and identifies effective His bundle capture based on the electrical dyssynchrony data. The computing apparatus generates an indication of His bundle capture in response to identifying the effective His bundle capture.

Abstract: Aspects of the disclosure generally relate to systems and methods for transcatheter delivery of an implant, such as a prosthetic heart valve, to a target site. Such systems can include a delivery system and an implant having a brim secured to an anchoring member. Systems and methods of the disclosure can include everting the brim of the prosthetic heart valve so that the everted brim and a capsule of the delivery system collectively sheathe the anchoring member of the prosthetic heart valve during delivery of the prosthetic heart valve to the target site.

Abstract: A heart valve prosthesis including a frame and a skirt. The frame including an inner portion configured to support a prosthetic valve component, and an outer portion coupled to the inner portion, the outer portion surrounding the inner portion and configured to anchor the prosthesis. The outer portion including a plurality of first crowns positioned around a first end of the outer portion and a plurality of second crowns positioned inward of the plurality of first crowns. The inner and outer portions are coupled at a plurality of pairs of adjoining crowns. The skirt is disposed within and is coupled to the outer portion, wherein an end segment of the skirt, disposed proximate to the first end of the outer portion, does not substantially extend past an endmost node of the outer portion so as to leave unobstructed a blood flow passageway through each pair of adjoining crowns.

Abstract: Systems, devices and methods for maintaining coronary access after implanting a prosthetic heart valve and/or a transcatheter prosthetic heart valve replacement procedure. Systems of the present disclosure include a support structure and a valve structure. The support structure includes inner and outer frame members that define at least one auxiliary passageway. Upon final implantation, the valve structure is connected to the inner frame member, and the auxiliary passageway provides for passage of an auxiliary access device. In some embodiments, the inner frame member is formed or provided by a stent otherwise maintaining the valve structure. In other embodiments, the valve structure is secured to a stent of a prosthetic heart valve that is implanted separately from the support structure.

Abstract: An example system includes communication circuitry configured to communicate with a medical device system, memory communicatively coupled to the communication circuitry and being configured to store an identifier associated with the medical device system and a subscription service level of a patient, and processing circuitry communicatively coupled to the communication circuitry and the memory. The processing circuitry is configured to control the communication circuitry to receive a communication associated with the medical device system, the communication comprising an identifier. The processing circuitry is configured to determine, based on the identifier, the subscription service level of the patient. The processing circuitry is configured to generate, based on the subscription service level of the patient, a configuration message and control the communication circuitry to transmit the configuration message to the medical device system.

Abstract: A ventricular pacemaker is configured to determine a ventricular rate interval by determining at least one ventricular event interval between two consecutive ventricular events and determine a rate smoothing ventricular pacing interval based on the ventricular rate interval. The pacemaker is further configured to detect an atrial event from a sensor signal and deliver a ventricular pacing pulse in response to detecting the atrial event from the sensor signal. The pacemaker may start the rate smoothing ventricular pacing interval to schedule a next pacing pulse to be delivered upon expiration of the rate smoothing ventricular pacing interval.

Abstract: A fixation mechanism of an implantable medical device is formed by a plurality of tines fixedly mounted around a perimeter of a distal end of the device. Each tine may be said to include a first segment fixedly attached to the device, a second segment extending from the first segment, and a third segment, to which the second segment extends. When the device is loaded in a lumen of a delivery tool and a rounded free distal end of each tine engages a sidewall that defines the lumen, to hold the tines in a spring-loaded condition, the first segment of each tine, which has a spring-biased pre-formed curvature, becomes relatively straightened, and the third segment of each tine, which is terminated by the free distal end, extends away from the axis of the device at an acute angle in a range from about 45 degrees to about 75 degrees.

Abstract: The disclosure is directed to programming implantable stimulators to deliver stimulation energy via one or more implantable leads having complex electrode array geometries. The disclosure also contemplates guided programming to select electrode combinations and parameter values to support efficacy. The techniques may be applied to a programming interface associated with a clinician programmer, a patient programmer, or both. A user interface permits a user to view electrodes from different perspectives relative to the lead. For example, the user interface provides a side view of a lead and a cross-sectional view of the lead. The user interface may include an axial control medium to select and/or view electrodes at different axial positions along the length of a lead, and a rotational control medium to select and/or view electrodes at different angular positions around a circumference of the lead.

Abstract: Techniques and devices for implementing the techniques for adjusting atrial arrhythmia detection based on analysis of one or more P-wave sensing windows associated with one or more R-waves. An implantable medical device may determine signal characteristics of the cardiac signal within the P-wave sensing window, determine whether the cardiac signal within the sensing window corresponds to a P-wave based on the determined signal characteristics, determine a signal to noise ratio of the cardiac signal within the sensing window, update the arrhythmia score when the P-wave is identified in the sensing window and the determined signal to noise ratio satisfies a signal to noise threshold.
