    Abstract: An implantable medical device assembly includes a mounting structure, an electrode, and fixation tines. The electrode protrudes from a surface of the structure, offset proximally from a distal end of the structure, and approximately centered between first and second sides of the structure. Each tine extends away from the surface—a first adjacent the first side, and a second adjacent the second side. Each tine is elastically deformable from a relaxed condition, in which the tine extends toward a proximal end of the structure, to an extended condition, in which the tine extends away from the distal end of the structure. A delivery tool has first and second longitudinally extending sidewalls to receive passage of the structure therebetween. When the structure distal end is located between proximal ends of the sidewalls, a rail-like edge of each sidewall receives, and elastically deforms to the extended condition, a corresponding tine.

    Abstract: An implantable medical device assembly includes a mounting structure, an electrode protruding from a surface of the structure, between opposing sides thereof, and tissue-penetrating fixation tines, each extending from a corresponding shoulder of the structure surface, adjacent to the opposing sides. In a relaxed condition, each tine extends away from the surface and then bends toward a proximal end of the structure and back toward the surface. In an extended condition, each tine bends toward a distal end of the structure and extends along the corresponding shoulder. A holding member of a delivery tool has opposing sidewalls defining a cavity, wherein each sidewall includes a rail-like edge that fits in sliding engagement with a corresponding shoulder, to deform a corresponding tine into the extended condition, when an operator passes the assembly into the cavity. Applying a push force, to move the assembly back out form the cavity, releases the tines.

    Abstract: A device includes a signal generator module, a processing module, and a housing. The signal generator module is configured to deliver pacing pulses to an atrium. The processing module is configured to detect a ventricular activation event and determine a length of an interval between the ventricular activation event and a previous atrial event that preceded the ventricular activation event. The processing module is further configured to schedule a time at which to deliver a pacing pulse to the atrium based on the length of the interval and control the signal generator module to deliver the pacing pulse at the scheduled time. The housing is configured for implantation within the atrium. The housing encloses the stimulation generator and the processing module.

    Abstract: A relatively compact implantable medical device includes a fixation member formed by a plurality of fingers mounted around a perimeter of a distal end of a housing of the device; each finger is elastically deformable from a relaxed condition to an extended condition, to accommodate delivery of the device to a target implant site, and from the relaxed condition to a compressed condition, to accommodate wedging of the fingers between opposing tissue surfaces at the target implant site, wherein the compressed fingers hold a cardiac pacing electrode of the device in intimate tissue contact for the delivery of pacing stimulation to the site. Each fixation finger is preferably configured to prevent penetration thereof within the tissue when the fingers are compressed and wedged between the opposing tissue surfaces. The pacing electrode may be mounted on a pacing extension, which extends distally from the distal end of the device housing.

    Abstract: Devices, systems, and methods deliver implantable medical devices for ventricular-from-atrial (VfA) cardiac therapy. A VfA device may be implanted in the right atrium (RA) with an electrode extending from the right atrium into the left ventricular myocardium. A flexible leed, or another probe, may be advanced to the potential implantation site and used to identify a precise location for implantation of a medical device, such as an electrode, leadlet, lead, or intracardiac device. Some methods may include locating a potential implantation site in the triangle of Koch region in the right atrium of a patient's heart; attaching a fixation sheath to the right-atrial endocardium in the potential implantation site; and implanting the medical device over a guide wire at the potential implantation site. An implantable medical device may include an intracardiac housing and a leadlet, which may be delivered by these methods.
