Abstract: An interatrial shunting device including a tube and an anchoring assembly. The tube defines a first end opposite a second end, and a tube wall extending to and between the first and second ends. The tube wall is a solid body and defines a lumen of the tube, with the lumen being open at the first and second ends. The anchoring assembly is carried by the tube and is configured to secure the interatrial shunting device to a native atrial septum. The solid wall tube prevents tissue overgrowth across the atrial septum, and can have minimal exposure of the device in the left atrium to minimize stroke and other risks. In some examples, the anchoring assembly is configured to be self-transitionable from a delivery state to a deployed state.

Abstract: A medical device is configured to sense a cardiac electrical signal and determine from the cardiac electrical signal at least one of a maximum peak amplitude of a positive slope of the cardiac electrical signal and a maximum peak time interval from a pacing pulse to the maximum peak amplitude. The device is configured to determine a capture type of the pacing pulse based on at least one or both of the maximum peak amplitude and the maximum peak time interval.

Abstract: A pacemaker has a housing and a therapy delivery circuit enclosed by the housing for generating pacing pulses for delivery to a patient's heart. An electrically insulative distal member is coupled directly to the housing and at least one non-tissue piercing cathode electrode is coupled directly to the insulative distal member. A tissue piercing electrode extends away from the housing.

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: A method includes locating the triangle of Koch region in the right atrium of a patient's heart; securing at least one electrode of an implantable lead or device to cardiac tissue from the triangle of Koch region to deliver ventricle-from-atrium (VfA) cardiac therapy; and testing the location or depth of the at least one electrode to configure VfA cardiac therapy. Locating the target implant region in the triangle of Koch region may include detecting an atrial slow pathway potential (ASP) or atrial pacing output.

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 medical device delivery system includes a delivery catheter including an elongated body with a first portion defining a first lumen and a second portion defining a second lumen. An angle is defined between a first axis and a second axis defined by the first and second portions, respectively. The second axis points toward the left ventricular (LV) apex of the patient's heart when the first axis points into the CS. The first portion or an elongated element may extend into the CS to anchor the delivery catheter to the orientation of the CS.

Abstract: A method of creating a shunt between a right atrium and a left atrium of a mammalian heart including puncturing an atrial septum between the right atrium and the left atrium to create a shunt. An ablation device having balloon is advanced at least partially through the shunt. The balloon is inflated and configured to thermally isolate the atrial septum from blood within the left atrium and the right atrium. Ablation energy is delivered to ablate the atrial septum.
