    摘要： The disclosure describes an implantable medical lead for delivering stimulation to a patient. Electrodes may be located on two or more surfaces of the lead to, for example, selectively deliver stimulation to one or more tissue layers within the patient. The lead may be implanted within or between intra-dermal, deep dermal, or subcutaneous tissue layers, and may be used to, for example, deliver peripheral nerve field stimulation to treat pain experienced by the patient at the site at which the lead is implanted. The lead may comprise a paddle lead or a multiple level lead, e.g., a lead having a plurality of flat or paddle shaped lead bodies arranged in substantially parallel planes. Further, the lead may include fixation structures on the distal end, proximal end, or both ends to prevent migration.

    摘要： An implantable medical device (IMD) with a housing and electrodes on at least two surfaces of the housing is described. The surfaces may be, for example, opposed, substantially parallel surfaces, e.g., top and bottom surfaces. Location of electrodes on multiple surfaces of the housing may allow the IMD to deliver stimulation to a variety of tissues and with a variety of current field configurations. For example, the IMD may deliver peripheral nerve field stimulation (PNFS) to one or more tissue areas via electrodes selected from one or both of the surfaces to, for example, reduce the sensation of pain in a tissue area proximate to an implantation site of the IMD without targeting a specific nerve. The IMD may be implanted between or within intra-dermal, deep dermal, or subcutaneous layers of the tissue of the patient to deliver PNFS to any one or more of these layers.

    摘要： Delivery of peripheral nerve field stimulation (PNFS) in combination with one or more other therapies is described. The other therapy delivered in combination with PNFS may be, for example, a different type of neurostimulation, such as spinal cord stimulation (SCS), or a drug. PNFS and the other therapy may be delivered simultaneously, in an alternating fashion, according to a schedule, and/or selectively, e.g., in response to a request received from a patient or clinician. A combination therapy that includes PNFS may be able to more completely address complex or multifocal pain than would be possible through delivery of either PNFS or other therapies alone. Further, the combination of PNFS with one or more other therapies may reduce the likelihood that neural accommodation will impair the perceived effectiveness PNFS or the other therapies.

    摘要： The disclosure describes an introducer for facilitating implantation of therapy elements into a patient. The introducer has an elongated body that defines a lumen for advancement of a therapy element to an implant site, and includes a curved portion medially located between substantially straight proximal and distal portions. As an example, the shape of the introducer may allow a clinician to more easily, and without substantially damaging surrounding tissue, find the correct tissue depth and follow that tissue depth to the implant site. For example, the introducer may facilitate implantation of a therapy element within or between desired layers of tissue of the patient. In some embodiments, fluid may be injected through the introducer to create a space within the tissue to implant the therapy element. Fluid may also be evacuated through the introducer prior to implantation.

    摘要： A pulse stimulation system configured for implantation into a patient's body comprises a pulse stimulator, a conductive stimulation lead having a proximal end electrically coupled to the pulse simulator and having a distal end, and an electrode assembly coupled to the distal end of the stimulation lead. The electrode assembly comprises an electrode body having a therapy electrode thereon that is electrically coupled to the stimulation lead for delivering therapy to the patient. A floating electrode is configured to contact the patient's body tissue and has a surface area substantially larger than that of the therapy electrode. A filter is coupled between the therapy electrode and the floating electrode for diverting RF energy toward the floating electrode and away from the therapy electrode.

    摘要： Implantable lead assembly including a lead body, an elongated conductor, a coiled electrode, and a tether line. The lead body maintains the conductor. The electrode is coupled to the conductor, defining proximal and distal ends. The tether line defines a trailing segment and a leading segment terminating in a leading end. The tether line is coupled to the coiled electrode at a point proximal the distal end, and the leading end extends distal the distal end. With this configuration, a pulling force applied to the leading segment is transferred to the electrode at a point proximal the distal end as a pushing force, thereby minimizing an opportunity for overt stretching of the coiled electrode during implantation. The lead assembly can further include a needle connected to the tether line.
