Method of making an intervertebral disc prosthesis
First Claim
1. A method of treating a diseased or damaged intervertebral disc having a nucleus pulposus and an annulus, the method comprising the steps of:
- accessing the intervertebral disc for receipt of the biomaterial;
delivering under pressure the quantity of the curable biomaterial to the nuclear cavity through a first lumen;
venting though a second lumen a region proximate a distal end of the first lumen to a region exterior to the nuclear cavity;
at least partially curing the delivered biomaterial in such a manner that the at least partially cured biomaterial is retained in the nuclear cavity to comprise an intervertebral prosthesis, and contouring the at least partially cured, retained biomaterial to achieve a desired conformation approximating that of the nuclear cavity.

Abstract
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.

20. A method of treating a diseased or damaged intervertebral disc, the method comprising the steps of:
-
(a) accessing and preparing a site in the intervertebral disc for receipt of the biomaterial; (b) delivering under pressure through a first lumen a quantity of the curable biomaterial to the intervertebral disc; and (c) venting though a second lumen a region proximate a distal end of the first lumen to a region exterior to the intervertebral disc, and at least partially curing the delivered biomaterial while retained in the intervertebral disc in such a manner that the at least partially cured biomaterial is contoured to comprise an intervertebral prosthesis. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
