Abstract: A method of replacing a nucleus pulposus material wherein curable nucleus pulposus material is injected into a balloon in an intervertebral space. The balloon has an inlet port and an outlet port that are connected to a pressure-measuring device. After the catheter is placed in the intervertebral space, the balloon is filled with a radio-opaque solution until the desired balloon volume is attained. The nucleus replacement material is then fed into the inlet port of the balloon, while the radiopaque agent is allowed to leave via the outlet port. Once the balloon is completely filled and curing of the curable nucleus replacement material is accomplished, the catheter and ports are removed, and the annular defect can be sealed.

Abstract: An implantable pump and methods for detecting leaks in an implantable pump are provided. In one embodiment, the implantable drug pump includes a housing having at least one inlet port and an outlet port formed therein. The outlet port is adapted to communicate with a catheter for delivering fluid to a patient's body, and the inlet port(s) are effective to deliver fluid into the housing. The housing further includes at least one reservoir disposed therein and effective to contain a fluid. In use, the pump preferably includes a fluid having one or more drugs disposed in at least one of the reservoirs, and a radiolucent fluid disposed in one of the reservoirs. A user programmable control mechanism is coupled to the drug pump and is effective to selectively control movement of the valves between the open and closed positions.
