ABSTRACT:
A valve that is adapted to control the flow rate of fluid flow from an implantable pump or other fluid delivery device is provided. In general, the valve includes a multi-lumen member that is adapted to receive fluid-flow therethrough, and a restrictor member that is coupled to the multi-lumen member such that the restrictor member is effective to selectively restrict at least a portion of one or more lumens in the multi-lumen member to thereby adjust the flow rate of fluid flowing through the multi-lumen member. The valve can be built into an implantable drug pump to control fluid flow exiting the pump, or alternatively the valve can disposed within a catheter or otherwise coupled to an outlet port in an implantable drug pump to control the flow rate of fluid exiting the drug pump.
