Patent number: 7766965Abstract: A method of treating a diseased or damaged intervertebral disc having a nucleus pulposus and an annulus. The method includes the steps of accessing and preparing the intervertebral disc for receipt of the biomaterial by removing at least a portion of the nucleus pulposus to create a nuclear cavity. A quantity of the curable biomaterial is delivered under pressure to the nuclear cavity. The delivered biomaterial is at least partially cured in such a manner to retain it in the nuclear cavity. The at least partially cured biomaterial is contoured to achieve a desired conformation approximating that of the nuclear cavity.Type: GrantFiled: June 30, 2006Date of Patent: August 3, 2010Assignee: Disc Dynamics, Inc.Inventors: Qi-Bin Bao, Robert Garryl Hudgins, Jeffrey C.

Patent number: 7713301Abstract: A system for repairing an intervertebral disc by delivering and curing a biomaterial in situ within the disc. The system includes both a device, having an insertable balloon and related lumen, controls and adapters, as well as an in situ curable biomaterial (and related biomaterial delivery means). The system can allow the doctor to determine a suitable endpoint for biomaterial delivery, by controlling distraction and/or biomaterial delivery pressure, and in turn, to deliver a desired quantity of biomaterial to the balloon in order to achieve improved polymer cure and implant characteristics. Also provided is a related method for repairing an intervertebral disc by using such a system to deliver and cure the biomaterial in situ. The system can be used to implant a prosthetic total disc, or a prosthetic disc nucleus in a manner that leaves the surrounding disc tissue substantially intact.Type: GrantFiled: March 29, 2006Date of Patent: May 11, 2010Assignee: Disc Dynamics, Inc.Inventors: Qi-Bin Bao, Robert Garryl Hudgins, Jeffrey C.
