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.

Safety needle assembly with correct medication connection
InactiveUS20070179454A1Smooth connectionReadily matableSurgical needlesFiltering accessoriesLocking mechanismEpidural needles
To ensure that there is no misconnection between a needle, such as for example a spinal or epidural needle, and the appropriate medication, the needle hub the needle is formed, by molding or extrusion, to have a given configuration. An adapter is placed between the needle and a conventional fluid store, or medical line. The end of the adapter that connects to the needle assembly is formed to have a configuration that is complementary to that of the hub of the needle assembly, so that the adapter and the needle hub may be readily mated to each other. The other end of the adapter is formed to have another configuration, for example a conventional luer, that is readily connectable to a conventional fluid store, such as a syringe that has a conventional luer. The adapter is formed by inter-fitting two elements to effect an integral locking mechanism to prevent the uncoupling of the fluid store and the adapter, once they are securely coupled. By thus configuring the hub of the needle to have a given configuration that is matable only to the end of an adapter that has a complementary configuration, and further providing an adapter that prevents the removal of the fluid store connected thereto, the potential for mis-connecting the needle to a fluid store that contains a different medicament is greatly reduced, if not totally eliminated.

Epidural catheter system and methods of use
InactiveUS20070083184A1Elasticity can be extremely flexibleEasy to useSurgical needlesMedical devicesSterile environmentSTERILE FIELD
An epidural injection is used in medical procedure to administer medication to a patient's epidural space in the spine, usually to alleviate pain. Although effective in purpose, current medical procedure to administer an epidural injection does contain a flaw that exposes the patient to possible infection, usually manifested as an epidural abscess or bacterial meningitis. A source for infection stems from the manner the epidural catheter, specifically the proximal end not being inserted into the patient, is traditionally handled throughout the procedure—usually freely hanging, susceptible to breaking the sterile field and becoming contaminated. The current invention, an epidural catheter dispenser system, seeks to eliminate this risk of epidural catheter contamination by maintaining the epidural catheter, especially the proximal catheter end, in a sterile dispenser that can be easily manipulated by a physician. The epidural catheter dispenser system defines an inner cavity in which an epidural catheter may be loaded. When ready for use, a distal catheter end is extracted from the dispenser's inner cavity through a dispenser aperture on the dispenser's distal end piece, or top, allowing the physician to direct the epidural catheter into an epidural needle bore and into a patient's epidural space. Because the epidural catheter dispenser system and its epidural catheter contents fit easily into the palm of a physician's hand, the proximal catheter end is permanently in a controlled, contained sterile environment throughout the entire catheter placement procedure until extracted from the dispenser. The current invention minimizes and virtually eliminates the risk of epidural catheter contamination. Thus, the epidural catheter dispenser system provides benefits beyond existing epidural injection procedures including: (1) reduced risk of infection of the patient receiving an epidural injection; (2) easier catheter management for the physician; (3) better control of the medical microenvironment for the physician; and (4) improved medical efficiencies.
