    摘要: Apparatus and method for minimally invasive spinal surgery employs an elongated flexible guide element inserted so as to pass in through a first lateral posterior incision, through the spinal column anterior to the spinal cord, and out through a second lateral posterior incision contralateral to said first incision. The guide element is used to guide various elements to a desired position within the spinal column as part of the surgical procedure. Preferably, two hollow rigid tubes rigidly coupled outside the body in converging relation are used to define a working gap within the spinal column through which the guide element passes. This provides a platform for manipulation of tissues and introduction of implants anterior to the spinal cord. Procedures described include reinforcement of a degenerative intervertebral disc and restoration of a damaged vertebral body.

    摘要: A degenerated nucleus pulposus located in a central core region of an intervertebral disc within the annulus fibrosus is supplemented or replaced by a method wherein an amount of a biocompatible material is introduced into the central core region by a process including the steps of 1) forming a channel through a vertebral body adjacent to said intervertebral disc, extending from an exterior surface of the vertebral body to the central core region of the annulus fibrosus; 2) introducing an amount of a biocompatible material through the channel into the central core region of the annulus fibrosus; 3) pressurizing the biocompatible material through the channel to a postsurgical pressure sufficient to alleviate symptoms caused by the degenerated nucleus pulposus; and 4) sealing the channel while maintaining the sufficient postsurgical pressure. After sealing the channel, a vertebroplasty may optionally be performed in the vertebra.

    摘要: An artificial intervertebral disc and disc nucleus are described herein having chambers and dampening members. The dampening members may be within or outside of the main body of the device. The chambers may be filled with a suitable liquid, gas, or both, and separated by valves to regulate flow of fluid between chambers, within a dampening member, between the main body and dampening member, or all of the above. Chambers may be filled with responsive hydrogels, EPAM, or other suitable materials, and the device may have activation plates or members, a strain gauge, a pressure sensor, or other means for detecting changes in the materials and/or triggering desired changes in the materials in order to mimic the behavior of a healthy native disc or disc nucleus. A control system may be in communication with the device for receiving feedback and delivering stimuli to initiate desired changes in the fluids or other materials. Membranes may be of variable permeability and may be metallized to ensure as low permeability as possible. Dampening members may be filled during manufacture with carbon dioxide or other suitable gas which may be in a supercritical state and allowed to return to ambient temperature and gaseous state or by other means. Methods of manufacture, delivery of the artificial disc and related structures, and methods of treatment are also described.
