    Abstract: Disclosed are various configurations of electrodes with accompanying extensions and wires configured to be attached at or near the left atrium of a heart to allow the device to be held snug against the endocardium and out of the blood flow for low energy defibrillation of the atria in response to atrial fibrillation or other atrial arrhythmias. The portion of the lead internal to the atrium (e.g., the left atrium) is restrained against the endocardium of the left atrium by way of a restraint mechanism. In one example, the electrode is configured to attach to the atrial septum, with wires containing memory-shaped metal to keep the wires against the heart wall. In yet another example, the electrode is configured to be part of a mitral valve device.

    Abstract: A lead engagement device is configured to be positioned in a lead lumen. The lead engagement device includes a hypotube. The hypotube includes a wall having an inner surface defining an inner lumen and an outer surface. The wall defines a longitudinal axis of the hypotube. A plurality of lead engagement fingers extend outwardly and proximally from the outer surface at acute angles, and planes in which the acute angles are disposed extend diagonally relative to the longitudinal axis. The plurality of lead engagement fingers are configured to translate relative to the lead and permit relative motion between the lead engagement device and the lead when applying a first force to the lead engagement device. The plurality of lead engagement fingers are configured to engage the lead and inhibit relative motion between the lead engagement device and the lead when applying an opposite second force to the lead engagement device.

    Abstract: A system is provided that includes a lead configured to be located within a septal wall, a monitor configured to obtain cardiac activity signals, and a memory configured to store program instructions. The system also includes one or more processors that, when executing the program instructions, are configured to obtain morphology data related to the cardiac activity signals indicative of the lead located at different depths within the septal wall, the morphology data including a set of data values associated with different depths of the lead within the septal wall, and determine when the lead is located at a target depth within the septal wall based on the morphology data.

    Abstract: A delivery device, a cardiac pacing device and a fixation structure are disclosed. The fixation structure includes a casing, a driving member and an elastic member. The casing has a first internal cavity and a slot, and the driving member is partially received in the first internal cavity in such a manner that one end of the driving member protrudes out of the first internal cavity from a proximal end thereof and is detachably connected to the driving sheath. The elastic member is accommodated in the first internal cavity in such a manner that its one end is coupled to the driving member and the other end extends outwardly from the driving member and is inserted in the slot. The driving member is configured for fitted connection with the casing while being able to move in an axial direction of the casing to drive the elastic member to move in the slot, thereby causing the elastic member to protrude out of or move back into the slot. As such, the cardiac pacing device can be fixed in a patient's body, allows retrieval and adjustment in pacing location, and features a simple structure, ease of operation, no limitation in tissue wall thickness and ease of fixation. Thus, the leadless pacing device can be fixed either in a ventricle or in an atrium to provide dual-chamber pacing and physiological pacing with atrioventricular synchronization.
