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.

Abstract: Delivery tools of interventional medical systems facilitate deployment of relatively compact implantable medical devices that include sensing extensions, for example, right ventricular cardiac pacing devices that include a sensing extension for atrial sensing. An entirety of such a device is contained within a delivery tool while a distal-most portion of the tool is navigated to a target implant site; the tool is configured to expose, out from a distal opening thereof, a distal portion of the device for initial deployment, after which sensing, via a sense electrode of the aforementioned sensing extension of the device, can be evaluated without withdrawing the tool from over the remainder of the device that includes the sensing extension.

Abstract: Delivery tools of interventional medical systems facilitate deployment of relatively compact implantable medical devices that include extensions, for example, cardiac pacing devices that include an extension for atrial sensing, wherein an entirety of the device is contained within the delivery tool while a distal-most portion of the tool is navigated to a target implant site. Once at the implant site, a device fixation member may be exposed out from a distal opening of the tool, for initial deployment, while the extension remains contained within the delivery tool. The tool includes a grasping mechanism, operable, within and without a lumen of the tool, to alternately grip and release the device extension, for example, to position a distal end of the extension after the tool has been withdrawn from over an entirety of the initially deployed device.
