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.

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 In one variation, a guide wire is inserted through a needle lumen, and the needle is withdrawn.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.

A method and system for providing electrical pulses for neuromodulating sacral nerves of a patient utilizing an implantable stimulator. The implantable stimulator comprising a pulse generator module and a stimulus receiver module for coupling with an external stimulator. Control circuitry ensures selective operation of one pulse generator module. The external stimulator comprises a telemetry module for remotely activating (or de-activating) programs over the internet, to arrive at the optimal program for each patient. Once the optimal “dose” is titrated using the external stimulator, the implanted pulse generator can then be programmed to such parameters. The external stimulator in conjunction with the implanted stimulus receiver can override the implanted pulse generator, to provide extra dose of therapy or to conserve the implanted battery. The external stimulator is also networked to other computers. The external programmer may also comprise a global positioning system (GPS) module for determining patient location.

A pulse generator is programmed to generate electrical stimulation to target a sacral nerve or a pudendal nerve of the patient. The electrical stimulation being delivered at least in part via a lead. The electrical stimulation is applied by ramping up a stimulation parameter over time. A first, a second, and a third physiological response are detected from the patient as a result of the electrical stimulation. A first value, a second value, and a third value of the stimulation parameter associated with the first, second, and third physiological response are measured, respectively. A placement of the lead inside the patient is evaluated based on at least one of: a chronological sequence in which the first, second, and third physiological responses occurred, a comparison of the first value with a predetermined threshold, or respective deviations of the second value or the third value from the first value.

An implantable electrical lead for applying stimulation energy to bodily tissue, such as a patient's nervous system, from an external power source. The lead is defined by a distal section, an intermediate section and a proximal section, and includes a lead body, a plurality of insulated wires, and a plurality of connector elements. The lead body includes a plurality of electrodes and an anchoring device. The insulated wires are electrically coupled to the electrodes, respectively. A wire intermediate segment extends proximal the lead body and is characterized as having a non-coiled configuration, terminating at a respective connector element for coupling to an external power source. The wire intermediate segments are extendible through a patient's skin and are sealable relative to the skin. The lead is adapted for providing temporary electrical stimulation to a sacral nerve in a bipolar mode, with the anchoring device inhibiting electrode migration.
