    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.

    Abstract: A medical system includes an implantable medical device that carries a first electrode on a distal end of the implantable medical device and a return electrode. The implantable medical device is configured to be positioned within a heart. The implantable medical device further includes a leadlet including a proximal end and a distal end. The proximal end is attached to the implantable medical device, and the distal end is configured to penetrate tissue of the heart. The leadlet carries a second electrode, and a body of the leadlet between the proximal end and the distal end is configured to flex when the distal end is implanted in the tissue of the heart. The implantable medical device further includes a fixation device attached to the implantable medical device. The fixation device is configured to affix the distal end of the implantable medical device to the heart.

    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.
