Dura mater is the outermost meningeal layer that covers the brain and spinal cord. It consists of two layers; the inner meningeal layer and the outer periosteal layer. The potential space between the layers of the dura mater is called the epidural space. The epidural space exists around both the brain and the spinal cord.

Disclosed is a lead for percutaneous insertion into an epidural space of a spinal canal, which includes an elongated lead body having opposed proximal and distal end portions. At least one electrode for stimulating a patient is operatively associated with the distal end portion of the lead body. Structure for conducting signals extends through the lead body to connect the electrode to a connecting structure operatively associated with the proximal end portion of the lead body. The connecting structure is capable of engaging a signal generator such that signals can be conducted from a signal generator to the electrode. The distal end portion of the lead body is adapted for movement between a first state, in which the distal end portion has a generally linear configuration, and a second state, in which the distal end portion has an undulating configuration.

Methods and apparatus are provided for selective surgical removal of tissue, e.g., for enlargement of diseased spinal structures, such as impinged lateral recesses and pathologically narrowed neural foramen. In one variation, tissue may be ablated, resected, removed, or otherwise remodeled by standard small endoscopic tools delivered into the epidural space through an epidural needle. Once the sharp tip of the needle is in the epidural space, it is converted to a blunt tipped instrument for further safe advancement. A specially designed epidural catheter that is used to cover the previously sharp needle tip may also contain a fiberoptic cable. Further embodiments of the current invention include a double barreled epidural needle or other means for placement of a working channel for the placement of tools within the epidural space, beside the epidural instrument. The current invention includes specific tools that enable safe tissue modification in the epidural space, including a barrier that separates the area where tissue modification will take place from adjacent vulnerable neural and vascular structures. In one variation, a tissue abrasion device is provided including a thin belt or ribbon with an abrasive cutting surface. The device may be placed through the neural foramina of the spine and around the anterior border of a facet joint. Once properly positioned, a medical practitioner may enlarge the lateral recess and neural foramina via frictional abrasion, i.e., by sliding the abrasive surface of the ribbon across impinging tissues. A nerve stimulator optionally may be provided to reduce a risk of inadvertent neural abrasion. Additionally, safe epidural placement of the working barrier and epidural tissue modification tools may be further improved with the use of electrical nerve stimulation capabilities within the invention that, when combined with neural stimulation monitors, provide neural localization capabilities to the surgeon. The device optionally may be placed within a protective sheath that exposes the abrasive surface of the ribbon only in the area where tissue removal is desired. Furthermore, an endoscope may be incorporated into the device in order to monitor safe tissue removal. Finally, tissue remodeling within the epidural space may be ensured through the placement of compression dressings against remodeled tissue surfaces, or through the placement of tissue retention straps, belts or cables that are wrapped around and pull under tension aspects of the impinging soft tissue and bone in the posterior spinal canal.

Neural stimulation lead fixation
An implantable lead having at least one electrode contact at or near its distal end prevents undesirable movement of the electrode contact from its initial implant location. One embodiment relates to a spinal cord stimulation (SCS) lead. A balloon may be positioned on the electrode lead array. The balloon is filled with air, liquid or a compliant material. When inflated, the balloon stabilizes the lead with respect to the spinal cord and holds the lead in place. The pressure of the balloon is monitored or otherwise controlled during the filling process in order to determine at what point the filling process should be discontinued. An elastic aspect of the balloon serves as a contained relief valve to limit the pressure the balloon may place on the surrounding tissues when the epidural space is constrained.

Multiprogrammable tissue stimulator and method
An electronic stimulation system is used to control pain over multiple regions of a patient's body. The system has one or more percutaneous leads, each having multiple electrodes, implanted within the patient's epidural space parallel to the axis of the spinal cord. The leads are connected to either a totally implanted system or a radio frequency system. The system is able to treat pain over different regions of a patient's body by “simultaneously” stimulating the patient with at least three different stimulation settings. “Simultaneous” stimulation involves sequentially stimulating the patient with the multiple stimulation settings such that the patient receives the cumulative effect of each stimulation setting, while not perceiving the transition from one stimulation setting to another.

ActiveUS20120215218A1Inhibit migrationPrevent rotationSpinal electrodesSurgical instruments for heatingElectrical impulseElectrical stimulations
Disclosed methods and devices treat chronic lower back pain from degenerated or injured intervertebral discs. Electrodes connected to a pulse generator deliver electrical impulses to nerves located within the posterior longitudinal ligament and annulus fibrosus of lumbar intervertebral discs. The stimulation reduces back pain reversibly, adjustably, and with almost complete coverage of the pain-generating region. A temporary percutaneous lead and a permanent paddle lead are used. The percutaneous lead, designed to prevent inappropriate stimulation of the thecal sac, is inserted using a specially-designed introducer cannula and lead blank. The paddle lead is configured individually for implantation in the anterior epidural space of each patient. Electrical stimulation parameters may also be selected so as to ablate the nerves, using non-thermal irreversible electroporation, or using joule heating wherein a thermal insulator covers substantially all of the thecal sac, thereby shielding the thecal sac from potential heat damage.

InactiveUS20060129028A1Stimulates arousalEscalationElectrotherapyNon-surgical orthopedic devicesSpinal columnElectrical conductor
A device and method for male impotence correction and female anorgasmy. An electronic stimulator with at least one pulse generator is implanted inside the body. At least one electrode is installed in the epidural space in the sacrum section of the spinal column and a conductor running under the user's skin electrically connects the electrode to the pulse generator. The stimulator is programmable and may be controlled from outside the body. Upon command initiated by the user or the user's lover the stimulator produces very short low-voltage electrical pulses in the sacrum section that are picked up by the nerves leading to the sex organs of the user, which stimulates arousal in the user's reproductive systems. The pulses are similar to the pulses generated by heart pacemakers. In other preferred embodiments the stimulator includes one or two drug chambers and a tube extending from each chamber to a nerve for producing stimulation of a sex organ. The present invention works on both males and females. In a preferred embodiment, the programmable electronic stimulator is implanted under the skin in the patient's back. Stimulation of the nerves coming out from the parasympathetic part of the spinal cord causes dilatation of the penile arteries in the male and in the clitoris arteries of the female, which results in an erection in the male and pre-orgasmic sensation in the female. In female, the stimulation of the sacral part of the spinal cord increases sexual desire and escalation to the level of orgasm. A preferred embodiment provides for emission stimulation. Emission is stimulated by electrical excitation of the sacral part of the spinal cord by increasing the voltage of the previous impulses. The device may be preprogrammed to set in motion the emission and ejaculation process at a predetermined time interval after the start of the erection process.
