Prosthetic spinal disc replacement
ActiveUS20050043800A1Restrict movementJoint implantsNon-surgical orthopedic devicesSpinal columnSurgical approach
The present invention relates generally to a prosthetic spinal disc for replacing a damaged disc between two vertebrae of a spine. The present invention also relates to a method for implanting a prosthetic spinal disc via posterior or posterior lateral implantation. Other surgical approaches for implanting the prosthetic disc may also be used. The present invention also involves a method for implanting the prosthetic spinal disc while either avoiding or minimizing contact with the spinal cord and nerve rootlets, or reducing the time and extent that they need to be repositioned during implantation.

Apparatus for directionally stimulating nerve tissue
This invention relates to an apparatus and method for making such apparatus for providing controlled and directional stimulation patterns for tissue stimulation. The apparatus may be useful in stimulation nervous tissue in the brain, about the spinal cord, on nerve roots, about peripheral nerves, and in muscles, among others. The apparatus includes a implantable pulse generator connected to a lead. The lead has electrodes placed about a perimeter. In addition, the lead may include electrodes placed longitudinally along the axis of the lead. By applying charge differences between circumferentially distributed electrodes, a smaller stimulation field may be established. In addition, by stimulating between electrodes distributed longitudinally on the same side, a directional flow field may be established. Such leads are especially useful in deep brain stimulation as the region in which a stimulation field is strong enough to produce tissue stimulation is directional and minimized.

InactiveUS20050004563A1Reduce the temperatureAvoid motor nerve damageSurgical needlesSurgical instruments for heatingThermal energySpinal nerve
Apparatus and methods for performing spinal disc lesioning procedures while monitoring the temperature near the spinal nerve roots. A needle containing a thermocouple and an injection bore may be placed between the disc and a nerve root. Temperature near the nerve root may be monitored during the lesioning procedure and if raised to a point where damage to the nerve could occur, the procedure may be stopped before damage is done. Coolant may be injected through the injection bore to lower the temperature near the nerve root. Additional dual purpose needles may be placed on the disc adjacent the opposite nerve root or in the spinal canal at the level of the disc for additional control. A hollow, flexible tip electrode needle may be used to repair and lesion the disc tissue. Prior to lesioning, the electrode may be stimulated to assess motor nerve response and avoid motor nerve damage.

Devices and methods for treatment of incontinence
InactiveUS6964643B2Increase blood flowPrevent involuntary contractionPneumatic massageDiagnosticsGenital regionGynecology
Therapeutic devices and methods according to embodiments of the invention alleviate e.g. urinary incontinence in female and male patients. Suction or vacuum, for example, is applied to the genital region, clitoris or clitoral region, the external urethral orifice, and / or other designated areas, e.g. physically stimulating the sacral / pudendal nerves and / or nerve roots and alleviating incontinence. Such embodiments also can encourage or cause clitoral engorgement, or otherwise promote blood flow in the genital region. Vacuum or suction applied to e.g. the clitoris creates a negative pressure in the clitoris that is lower than the systolic blood pressure, tending to promote engorgement of the clitoris with blood. Aspects of the invention are applicable not only to treatment of urinary and fecal incontinence, but also to the treatment of female sexual dysfunction. Aspects of the invention are also applicable to treatment of male incontinence and male erectile dysfunction.

Methods and devices for modulating excitable tissue of the exiting spinal nerves
ActiveUS20130310901A1TestingReduce postoperative painSpinal electrodesExternal electrodesCouplingMedicine
A method for modulating nerve tissue in a body of a patient includes implanting a wireless stimulation device in proximity to a dorsal root ganglion or an exiting nerve root such that an electrode, circuitry and a receiving antenna are positioned completely within the body of the patient. An input signal containing electrical energy and waveform parameters is transmitted to the receiving antenna(s) from a control device located outside of the patient's body via radiative coupling. The circuitry within the stimulation device generates one or more electrical impulses and applies the electrical impulses to the dorsal root ganglion or the exiting nerve roots through the electrode.
