    Abstract: Delivery devices, systems, and methods for delivering implantable leadless pacing devices are disclosed. An example delivery device may an outer tubular member and an inner tubular member slidably disposed within the lumen of the outer tubular member. A distal holding section may extend distally of a distal end of the inner tubular member and define a cavity therein for receiving an implantable leadless pacing device. The device may further include a hub portion including at least a first hub portion affixed adjacent to the proximal end of the outer tubular member and a second hub portion affixed adjacent to the proximal end of the inner tubular member. A first locking mechanism configured to releasably couple the outer tubular member and the inner tubular member may be disposed within the hub portion.

    Abstract: Systems, devices, and methods for pacing a heart of a patient are disclosed. In some embodiments, a method for pacing a patient's heart may include determining a posture of the patient and determining if the determined posture corresponds to a predetermined sleep posture. If the determined posture correspond to the predetermined sleep posture, the method may further comprise determining a respiration phase of the patient and pacing the patient's heart at a pacing rate that is modulated based on the determined respiration phase of the patient. If the determined posture does not correspond to the predetermined sleep posture, the method may pace the patient's heart at a pacing rate that is not dependent on the respiration phase of the patient.

    Abstract: A temporary implantable medical device lead includes a connector configured to connect the lead to an external control module. A helically coiled conductor includes a proximal end that is mechanically and electrically connected to the connector. The conductor includes a plurality of insulated filars. An insulative layer is removed from an uninsulated portion of each of the filars near a distal end of the conductor. The uninsulated portion of each of the filars is exposed at an outer surface of the conductor such that the exposed uninsulated portions of the filars define a plurality of electrodes at longitudinally spaced sections near the distal end of the conductor.

    Abstract: A retrieval device and an associated implantable cardiac pacing device. The retrieval device includes a grasping mechanism configured to capture a docking member of the implantable cardiac pacing device to draw the implantable cardiac pacing device into the lumen of a retrieval catheter. The grasping mechanism is expandable from a first position to a second position and is biased toward the first position in an equilibrium condition. The grasping mechanism is configured to surround and pass over a head portion of the docking member in the second position, and be contracted toward the first position to capture the docking member with the grasping mechanism.
