Implantable pump with adjustable flow rate
First Claim
1. A valve adapted to control the flow rate of fluid flow from an implantable pump, comprising:
- a multi-lumen member adapted to receive fluid-flow therethrough; and
a restrictor member 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.

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.

11. An implantable drug-delivery pump, comprising:
-
a housing having a reservoir adapted to retain a fluid therein;
a pump inlet port formed in the housing for delivering fluid to the reservoir;
a reservoir outlet port formed in the housing and adapted to receive fluid from the reservoir;
a driver mechanism effective to drive fluid from the reservoir to the reservoir outlet port; and
a valve in fluid communication with the reservoir outlet port, the valve including a multi-lumen member coupled to a restrictor member that is adapted 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 from the reservoir. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A method for controlling the flow rate of fluid being delivered to a patient from an implantable pump, comprising:
-
providing a valve in fluid communication with a reservoir formed in an implantable pump, the valve including a multi-lumen member coupled to a restrictor member that is adapted to selectively restrict at least a portion of one or more lumens to thereby adjust the flow rate of fluid flowing from the reservoir; and
actuating the restrictor member to selectively restrict at least a portion of one or more lumens to thereby adjust the flow rate of fluid flowing from the reservoir. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32)
