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 In one variation, a guide wire is inserted through a needle lumen, and the needle is withdrawn.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

Described are implantable devices and methods for treating various disorders of the pelvic floor by means of electrical stimulation of the pudendal and sacral nerves, or portions thereof, and optional means for delivering drugs in association therewith. Two or more electrical stimulation regimes are applied on a continuous, alternating, intermittent or other basis to the sacral and pudendal nerves, and optionally one or more drugs are infused, injected or otherwise administered, to appropriate portions of a patient's pelvic floor and pudendal nerve and/or sacral nerve, or portions thereof, in an amount and manner effective to treat a number of disorders, including, but not limited to, urinary and/or fecal voiding dysfunctions such as constipation, incontinence disorders such as urge frequency and urinary retention disorders, sexual dysfunctions such as orgasmic and erectile dysfunction, pelvic pain, prostatitis, prostatalgia and prostatodynia.

A method and system for providing pulsed electrical stimulation to sacral nerves and/or its branches, to provide therapy for urinary/fecal incontinence and other urological disorders. The stimulation system comprising implanted and external components. The pulsed electrical stimulation may be provided using a system which is one from a group comprising: a) an implanted stimulus-receiver with an external stimulator; b) an implanted stimulus-receiver comprising a high value capacitor for storing charge, used in conjunction with an external stimulator; c) a programmer-less implantable pulse generator (IPG) which is operable with an external magnet; d) a programmable implantable pulse generator; e) a combination implantable device comprising both a stimulus-receiver and a programmable IPG; and f) an implantable pulse generator (IPG) comprising a rechargeable battery. In one embodiment, the external components such as the programmer or external stimulator may comprise telemetry means for interrogation or programming of the implanted device from a remote location, over a wide area network.

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.

A method and system for neuromodulation therapy for urinary incontinence and urological disorders comprises an implantable lead stimulus-receiver, and an external stimulator-transmitter having a power source, controlling circuitry, and predetermined programs. The stimulator-transmitter further includes a primary coil which inductively transfers electrical signals to the lead-receiver, which is also in electric contact with the sacral nerves. The external stimulator-transmitter emits electrical pulses to stimulate the sacral plexus according to a predetermined program. In one mode of operation, the operator may program one of the predetermined programs, in another mode, the electrical parameters may be “custom” programmed for the patient, and stored in the memory.

The invention provides a wireless charging device and a sacral nerve stimulation system thereof. A charging receiving coil is arranged in an implant. When the electric quantity of a built-in battery is insufficient, an extracorporeal charging transmitting coil is arranged at the position matched with the charging receiving coil, and wireless charging for the built-in battery is performed through coupling between the coils. Besides, an intracorporeal charging control unit is also arranged in the implant to detect the electric quantity of the built-in battery and transmit the detected electric quantity information to the outside through the first antenna and the second antenna of the sacral nerve stimulation system so as to prompt a user to charge the built-in battery. Furthermore, when the built-in battery is charged, the charging receiving coil also supplies power to stimulating electrodes so as to ensure that the stimulating electrodes can still perform current stimulation on sacral nerves in charging. The risk of replacing the intracorporeal battery can be reduced for patients and the safety of the sacral nerve stimulation system can be increased.
