    Abstract: An implantable medical therapy delivery device includes a non-conductive filament extending along a length of an outer surface of an insulative body of the device, wherein the filament includes a plurality of fixation projections and is secured to the outer surface of the insulative body such that the projections protrude outward from the outer surface and are spaced apart from one another along the length of the outer surface. The filament may be wound about the length with an open pitch. In some cases, the insulative body includes an open-work member forming at least a portion of the outer surface thereof, and the filament may be interlaced with the open-work member. In these cases, the filament may be bioabsorbable, for example, to provide only acute fixation via the projections thereof, while the open-work member provides a structure for tissue ingrowth and, thus, more permanent or chronic fixation.

    Abstract: A medical electrical lead may include a conductive electrode shaft located near the distal end within the lead body, a coiled conductor extending within the lead body from the proximal end and coupled to a first end of the conductive electrode shaft, and an electrode located near the distal end of the lead body and coupled to an opposite end of the conductive electrode shaft as the coiled conductor. The lead may also include an energy dissipating structure located near the distal end of the lead body and defining a lumen through which a portion of the coiled conductor extends. The energy dissipating structure may include a region having one or more protrusions extending toward a central axis of the lumen to push the coiled conductor off center relative to the central axis of the lumen.

    Abstract: Implant tools and techniques for implantation of a medical lead, catheter or other component are provided. The implant tools and techniques are particularly useful in implanting medical electrical leads in extravascular locations, including subcutaneous locations. An implant tool for implanting a medical lead may include a shaft having a proximal end, a distal end, an open channel that extends from near the proximal end to the distal end, and an attachment feature configured to couple to the medical lead. Such an implant tool provides a user with the versatility to use the same implant tool to either pull the lead through a tunnel formed via the implant tool or push the lead through the tunnel via the open channel in the implant tool.

    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.
