    摘要： An implantable medical electrical lead particularly for stimulation of the sacral nerves comprises a lead body extending between a distal end and a proximal end, and the distal end having at least one electrode of an electrode array extending longitudinally from the distal end toward the proximal end. The lead body at its proximal end may be coupled to a pulse generator, additional intermediate wiring, or other stimulation device. A fixation mechanism is formed on or integrally with the lead body proximal to the electrode array that is adapted to be implanted in and engage subcutaneous tissue, particularly muscle tissue, to inhibit axial movement of the lead body and dislodgement of the stimulation electrodes. The fixation mechanism comprises a M tine elements arrayed in a tine element array along a segment of the lead proximal to the stimulation electrode array. Each tine element comprises at least N flexible, pliant, tines, each tine having a tine width and thickness and extending through a tine length from an attached tine end to a free tine end. The attached tine end is attached to the lead body from a tine attachment site and supports the tine extending outwardly of the lead body and proximally toward the lead proximal end. The M×N tines are adapted to be folded inward against the lead body when fitted into and constrained by the lumen of an introducer such that the tine free ends of more distal tines of more distal tine elements are urged toward or alongside the attached tine ends of the adjacent more proximal tines of more proximal tine elements, and the folded tines do not overlap one another.

    摘要： Methods and apparatus for implanting a stimulation lead in a patient's sacrum to deliver neurostimulation therapy that can reduce patient surgical complications, reduce patient recovery time, and reduce healthcare costs. A surgical instrumentation kit for minimally invasive implantation of a sacral stimulation lead through a foramen of the sacrum in a patient to electrically stimulate a sacral nerve comprises a needle and a dilator and optionally includes a guide wire. The needle is adapted to be inserted posterior to the sacrum through an entry point and guided into a foramen along an insertion path to a desired location. In one variation, a guide wire is inserted through a needle lumen, and the needle is withdrawn. The insertion path is dilated with a dilator inserted over the needle or over the guide wire to a diameter sufficient for inserting a stimulation lead, and the needle or guide wire is removed from the insertion path. The dilator optionally includes a dilator body and a dilator sheath fitted over the dilator body. The stimulation lead is inserted to the desired location through the dilator body lumen or the dilator sheath lumen after removal of the dilator body, and the dilator sheath or body is removed from the insertion path. If the clinician desires to separately anchor the stimulation lead, an incision is created through the entry point from an epidermis to a fascia layer, and the stimulation lead is anchored to the fascia layer. The stimulation lead can be connected to the neurostimulator to delivery therapies to treat pelvic floor disorders such as urinary control disorders, fecal control disorders, sexual dysfunction, and pelvic pain.

    摘要： A therapy assembly configured for at least partial insertion in a living body. A plurality of fixation structures are disposed radially around the therapy delivery element proximate the electrodes. The fixation structures include wires having a diameter in a range between about 0.004 inches and about 0.020 inches. The wires have a first end attached to the therapy delivery element and a second end attached to a sliding member configured to slide along the therapy delivery element. The fixation structures are configured to collapse inward to a collapsed configuration when inserted into a lumen of an introducer and to deploy to a deployed configuration when the introducer is retracted. A fitting is located at proximal end of the introducer that releasably locks the therapy delivery element to the introducer, such that torque applied to the fitting is substantially transmitted to the distal end of the therapy assembly.

    摘要： Suture anchors for securing therapy delivery elements, such as stimulation leads or catheters, within a living body. The suture anchor includes an inner sleeve constructed with an inner layer of a softer, more pliable material that easily conforms to the therapy delivery element to reduce slippage and an outer layer constructed from a harder, stiffer durometer material that protects the therapy delivery elements from damage due to over-tightening the tie down sutures. A suture material located in the suture groove is tensioned to apply a radial compressive force. The reinforcing structure spreads the radial compressive force along a greater surface area of the therapy delivery element.

    摘要： In general, the invention provides a transurethral ablation device comprising an electrode for delivery of neurostimulation therapy to a patient to prevent or alleviate pain experienced during the course of a transurethral ablation procedure. The device may include a conductive ablation needle that delivers electrical current for ablation of prostate tissue, as well as neurostimulation current to prevent or alleviate pain encountered in response to the ablation current. In this sense, the ablation needle is integrated with a neurostimulation electrode. Alternatively, the device may incorporate a dedicated neurostimulation electrode independently of the ablation needle, either on the needle or on a catheter body that carries the needle.
