1. An apparatus for forming an intervertebral disc prosthesis in situ, the device comprising: a collapsed balloon adapted to be positioned within an intervertebral disc space using minimally invasive techniques, the balloon having one or more exterior surfaces and one or more interior cavities, at least one of the interior cavities being adapted to receive a curable biomaterial; a catheter; at least first and second lumens fluidly coupled with an interior cavity of the balloon, the first lumen adapted to deliver biomaterial, and the second lumen adapted to evacuate fluid from the balloon during delivery of the biomaterial; a curable biomaterial adapted to be delivered to the balloon through the first lumen; at least one biomaterial delivery apparatus adapted to deliver at least one flowable biomaterial to the balloon through the at least one lumen while the balloon is located in the intervertebral disc space; and one or more fluid control devices adapted to control the flow of biomaterial from the biomaterial delivery apparatus to the balloon, the fluid control device comprising an endpoint monitor adapted to provide an indication of an endpoint for biomaterial delivery.
