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: 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grip and release the device extension, for example, to position a distal end of the extension after the tool has been withdrawn from over an entirety of the initially deployed device.

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 (IMD) including a fixation mechanism and a leadlet supporting an electrode. The leadlet includes a shape memory material configured to urge a leadlet body of the leadlet toward a preset orientation relative to a device body of the IMD. The leadlet is configured to establish a radial displacement between the device body and a distal end of the leadlet when the shape memory material urges the leadlet toward the preset orientation. The leadlet may be configured to cause the electrode to contact tissues of the heart when the fixation mechanism attaches to tissue of the heart and the shape memory material urges the leadlet toward the preset orientation.

Abstract: A medical system includes an implantable medical device that carries a first electrode on a distal end of the implantable medical device and a return electrode. The implantable medical device is configured to be positioned within a heart. The implantable medical device further includes a leadlet including a proximal end and a distal end. The proximal end is attached to the implantable medical device, and the distal end is configured to penetrate tissue of the heart. The leadlet carries a second electrode, and a body of the leadlet between the proximal end and the distal end is configured to flex when the distal end is implanted in the tissue of the heart. The implantable medical device further includes a fixation device attached to the implantable medical device. The fixation device is configured to affix the distal end of the implantable medical device to the heart.

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.
