Abstract: A capacitively loaded loop antenna for an implantable medical device is disclosed comprising a feed extending from a conductive surface of an implantable housing, a radiating element having a cross section larger than the feed, and a return coupling the radiating element to a conductive surface of the implantable housing. The radiating element can have a height above the top surface of the implantable housing, creating a capacitance between the radiating element and the conductive surface of the implantable housing configured to counteract the inductance of the capacitively loaded loop antenna.

Abstract: Delivery devices, systems, and methods for delivering implantable leadless pacing devices are disclosed. An example delivery device may include an intermediate tubular member and an inner tubular member slidably disposed within a lumen of the intermediate tubular member. A distal holding section may extend distally of a distal end of the intermediate tubular member and define a cavity therein for receiving an implantable leadless pacing device. The device may be configured to enable fluid flushing of the delivery device prior to use, to remove any air from within the device as well as providing the option of fluid flow during use of the delivery device.

Abstract: Delivery devices, systems, and methods for delivering an implantable leadless pacing device having an outer peripheral surface are disclosed. An example delivery device may include a proximal section including a distal end, and a distal holding section extending distally of a distal end of the proximal section. The distal holding section defines a cavity therein for receiving the implantable leadless pacing device, and may be configured to apply a holding force to the implantable leadless pacing device. In some cases, the distal holding section may be configured to apply a compressive force to the outer peripheral surface of the leadless pacing device when the leadless pacing device is disposed in the cavity.

Abstract: Systems, methods, and devices for determining occurrences of a tamponade condition are disclosed. One exemplary method includes monitoring an accelerometer signal of a leadless cardiac pacemaker attached to a heart wall, determining if a tamponade condition of the patient's heart is indicated based at least in part on the monitored accelerometer signal, and in response to determining that the tamponade condition is indicated, providing a notification of the tamponade condition for use by a physician to take corrective action.

Abstract: An implantable medical device (IMD) may be deployed within a patient's right atrium at a location near a right atrial appendage of the patient's heart in order to pace the patient's heart and/or to sense electrical activity within the patient's heart. In some cases, an IMD may be implanted within the right atrial appendage. The IMD may include an expandable anchoring mechanism configured to secure the IMD in place.

Abstract: Delivery devices, systems, and methods for delivering implantable leadless pacing devices are disclosed. An example delivery device may include a proximal section including a deflection mechanism for deflecting the proximal section, and a distal holding section extending distally of a distal end of the proximal section and defining a cavity therein for receiving an implantable leadless pacing device. The delivery device may include more than one deflection mechanism for deflecting the proximal section at multiple deflection regions. The delivery device may include more than one tubular member that are translatable relative to one another, and the one or more tubular members may include fixed curve portions. The delivery device may include an atraumatic or bumper tip at the distal end of the holding section.

Abstract: A device for the active fixation of an implantable medical lead includes a housing, a tine assembly, and rotatable shaft. The housing includes a proximal end for connecting to the lead and a distal end opposite the proximal end. The housing defines a housing lumen having a longitudinal axis extending between the proximal end and the distal end. The tine assembly is disposed within the housing lumen. The tine assembly includes at least one tine configured to self-bias from a linear configuration within the housing to a curved configuration outside of the housing. The rotatable shaft extends through the housing lumen. The shaft is configured to engage the tine assembly such that rotation of the shaft transitions the at least one tine between the linear configuration and the curved configuration.

Abstract: An implantable medical device includes operational circuitry, such as a therapy circuit. The implantable medical device also includes a power source configured to deliver energy to the operational circuitry, and a deactivation element configured to disable the therapy circuit. A power manager is configured to detect an end-of-life condition of the power source and, in response to detecting the end-of-life condition, cause the deactivation element to reversibly disable the therapy circuit.
