    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: Various fixation techniques for implantable medical device (IMDs) are described. In one example, an assembly comprises an IMD; and a set of active fixation tines attached to the IMD. The active fixation tines in the set are deployable from a spring-loaded position in which distal ends of the active fixation tines point away from the IMD to a hooked position in which the active fixation tines bend back towards the IMD. The active fixation tines are configured to secure the IMD to a patient tissue when deployed while the distal ends of the active fixation tines are positioned adjacent to the patient tissue.

    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: An implantable medical device system is configured to generate signals and deliver the signals to a heart of a patient. The implantable medical device system includes electronic circuitry configured to deliver cardiac pacing, couplings for an implantable medical lead receptacle, at least some of the couplings electrically connected with the electronic circuitry, a polymeric enclosure having the electronic circuitry contained therein, the polymeric enclosure formed of polymeric material filled around the electronic circuitry and couplings and forming the implantable medical lead receptacle. The implantable medical device may include a first cavity filled with a first material and a second cavity filled with a second material, and the first material is different than the second material.

    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: A leadless pacing system includes a leadless pacing device and a sensing extension extending from a housing of the leadless pacing device. The sensing extension includes one or more electrodes with which the leadless pacing device may sense electrical cardiac activity. The one or more electrodes of the sensing extension may be carried by a self-supporting body that is configured to passively position the one or more electrodes proximate or within a chamber of the heart other than the chamber in which the LPD is implanted.
