The spinal cord is a long, thin, tubular structure made up of nervous tissue, which extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. It encloses the central canal of the spinal cord, which contains cerebrospinal fluid. The brain and spinal cord together make up the central nervous system (CNS). In humans, the spinal cord begins at the occipital bone, passing through the foramen magnum and entering the spinal canal at the beginning of the cervical vertebrae. The spinal cord extends down to between the first and second lumbar vertebrae, where it ends. The enclosing bony vertebral column protects the relatively shorter spinal cord. It is around 45 cm (18 in) in men and around 43 cm (17 in) long in women. The diameter of the spinal cord ranges from 13 mm (¹⁄₂ in) in the cervical and lumbar regions to 6.4 mm (¹⁄₄ in) in the thoracic area.
Prosthetic spinal disc replacement

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.

Systems and methods for electrosurgery
InactiveUS7270658B2Use performanceAvoid cloggingSurgical needlesEndoscopesIntervertebral discSpinal cord
Methods and apparatus for selectively applying electrical energy to a target location within a patient's body, particularly including tissue in the spine. In a method of the invention high frequency (RF) electrical energy is applied to one or more active electrodes on an electrosurgical probe in the presence of an electrically conductive fluid to remove, contract or otherwise modify the structure of tissue targeted for treatment. In one aspect, a dura mater and spinal cord are insulated from the electrical energy by an insulator positioned on a non-active side of the probe. In another aspect, a plasma is aggressively formed in the electrically conductive fluid by delivering a conductive fluid to a distal end portion of the probe and aspirating the fluid from a location proximal of the return electrode. In another aspect, a distal end of an electrosurgical probe having at least one electrode on a biased, curved, bent, or steerable shaft is guided or steered to a target site within an intervertebral disc having a disc defect for treatment of tissue to be treated at the target site by the selective application of electrical energy thereto.

Method and apparatus for controlling a neural stimulus
ActiveUS20140236257A1Avoid misalignmentControlled levelSpinal electrodesDiagnostic recording/measuringMedicineSpinal cord
An implantable device applies and controls a neural stimulus. The device has a plurality of electrodes, and a stimulus source for providing a stimulus to be delivered from the electrodes to a neural pathway in order to evoke an action potential on the neural pathway, such as the spinal cord. A control unit controls application of a neural stimulus as defined by a set of parameter values and measures via measurement circuitry an evoked neural compound action potential response. The control unit determines from the measured evoked response a feedback variable, and compares it to a therapy map. The therapy map defines a therapeutic relationship of control variable to feedback variable. One or more of the stimulus parameter values are altered to effect the required change in the control variable. This process is performed iteratively to improve alignment of the feedback variable with the therapy map over time.

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.
