    摘要: A method for inserting an intervertebral disc prosthesis into a space between two vertebrae involves inserting the prosthesis partway into the space under constraint to prevent endplates of the prosthesis from articulating, releasing the prosthesis from constraint, and inserting the unconstrained prosthesis farther into the space. In some embodiments, the method involves grasping the prosthesis with a grasping device to insert the prosthesis partway under constraint, loosing the grasping device to release the prosthesis from constraint, and pushing the prosthesis farther into the disc space using the grasping device and/or one or more separate pusher devices. A system includes a grasping device, at least one separate pushing device, and optionally a vertebral spreading device and/or a vertebral midline indicator device.

    摘要: Apparatus and methods for treating a target tissue by delivering a fluid at a defined temperature to a patient's body. An apparatus of the invention includes a fluid delivery unit for delivering fluid in at least close proximity to the target tissue, an aspiration unit for withdrawing the fluid, and a fluid source unit for providing the fluid at the defined temperature. A method of the invention includes forming a void in at least close proximity to the target tissue, and circulating a preheated fluid through the void, wherein the target tissue undergoes adjustment from body temperature to a treatment temperature due to heat exchange between the fluid and the target tissue.

    摘要: A prosthetic disc for insertion between adjacent vertebrae includes upper and lower plates and a core having upper and lower curved surfaces disposed between the plates. At least one of the plates and/or the core includes a resilient material for absorbing shock or other forces applied by vertebrae. Optionally, resilient support members may be disposed within the resilient material to connect two portions of a plate or the core. Such support members may be springs, cylinders, wires or other resilient structures. The resilient material is held within the core or plate(s) via a surrounding retaining structure, such as a membrane. The resilient material disposed in one or more components of the prosthetic disc provides for shock absorption.
