    摘要： A vented needle is provided for use in sealably injecting biomaterial into an intradiscal space interiorly of the annulus of a spinal disc and for providing an exhaust for the intradiscal space. The vented needle comprises a compressible seal body for pressing against an outer surface of the annulus, and a needle extending through the seal. The needle may be configured to connect to a syringe for pressure injection of the biomaterial into the needle. The seal includes a vent extending therethrough the seal with an opening for communication with the intradiscal space and an opening for the discharge of excess biomaterial filling the intradiscal space. A kit of parts is also provided for use in the treatment of a spinal disc, the kit comprising the vented needle and an inflatable trial device. The trial device is adapted to be removably introduced into the intradiscal space and inflated therein with a medium capable of determining the size of said intradiscal space created by the removal of at least a portion of said nucleus pulposus.

    摘要： A method for treating a herniated spinal disc between opposing vertebral bodies having a damaged outer annulus and an inner nucleus pulposus comprises the steps of: providing access to the nucleus pulposus through the annulus; removing at least a portion of the nucleus pulposus to create an intradiscal space; applying a first distraction force on the opposing vertebral bodies from within the intradiscal space; applying a second distraction force on the opposing vertebral bodies externally of the intradiscal space; and introducing a curable biomaterial through the annulus access directly into the intradiscal space. The first distraction force is applied within the disc space to distract the anterior aspect of the intradiscal space, while the second distraction force is applied exterior to the disc to act on the posterior aspect of the vertebral bodies. The first distraction force is applied prior to the application of the second distraction force and then removed. The second distraction force is maintained during the introduction of the biomaterial into the intradiscal space.

    摘要： A method for treating a diseased or damaged spinal disc comprises the steps of: (a) providing access to the nucleus pulposus through the annulus; (b) removing at least a portion of the nucleus pulposus to create an intradiscal space; determining the size of the intradiscal space; and (c) sealably introducing under pressure a curable biomaterial through the annulus directly into the intradiscal space. The method may include the additional steps of applying a force to distract the opposing vertebral bodies about the intradiscal space and then removing the distraction force after the biomaterial has cured. The step of determining the size of the intradiscal space may be accomplished by expanding a compliant balloon within the intradiscal space using a contrast medium capable of visualization under fluoroscopy. The curable material is sealably introduced through a vented needle inserted through the opening. The curable biomaterial is introduced until a quantity of the material flows into the vent.
