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: Methods and systems for positioning a leadless pacing device (LPD) in cardiac tissue are disclosed. A delivery device is employed that comprises a proximal end, a distal end and a lumen therebetween sized to receive the LPD. The LPD has a leadlet extending therefrom that includes a means to fixate the leadlet to tissue. The delivery device comprises an introducer to introduce the LPD into the lumen of the delivery device. The LPD is loaded in the distal end of the lumen of the delivery device. The leadlet extends proximally from the LPD while the fixation means extends distally toward the LPD. A LPD mover is configured to advance the LPD out of the delivery device. A leadlet mover is configured to advance the leadlet out of the lumen delivery device and cause the leadlet to engage with cardiac tissue.

Abstract: The present disclosure is directed to a shuttle apparatus for detachably joining a catheter to a guidewire so that the joined catheter, extending alongside the guidewire, is in sliding engagement with the guidewire without extending around the guidewire. The apparatus comprises a collar member sized for mounting in sliding engagement around a length of the guidewire, the collar member having a longitudinal axis that approximately aligns along the length, when mounted thereabout, the length being defined between a proximal-most point of the guidewire and a distal point of the guidewire, the distal point being offset proximally from a distal-most point of the guidewire. The apparatus further comprises a plug member coupled to the collar member, the plug member having a longitudinal axis, and the plug member being sized to fit within an opening of the catheter for detachable engagement therewith.

Abstract: A medical delivery device for delivering a medical device includes a navigable elongated member, a deployment bay, and a compression mechanism. The deployment bay may be configured to house the medical device as the medical device is navigated to the target site. The deployment bay may be at a distal end of the delivery device and may include a distal opening through which the medical device may be deployed. The compression mechanism is configured to longitudinally compress in response to a predetermined force such that the elongated member and deployment bay are relatively closer together along a longitudinal axis of the delivery device.

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: An apparatus for forming a passageway through tissue includes a dilator mounted to a shaft, wherein the dilator includes a first portion, which has an increasing taper from a first outer diameter to a larger second outer diameter, and a second portion, which has a decreasing taper from the first portion to a distal end of the dilator, and which includes an external non-cutting thread formed along the decreasing taper. Lumens of the dilator and shaft provide a conduit for means to pierce through the tissue, for example, an elongate wire that includes a piercing tip. In some cases, the dilator first portion is expandable to, and contractible from, the larger second outer diameter, wherein the apparatus may include a spreading member configured to slide between the shaft and the first portion. The apparatus may be included in a system with an introducer sheath.
