Abstract
A valve for controlling material flow through a catheter, comprises a first flexible member including a first moveable element, wherein, when the first moveable element is in the open position, material may flow past the first flexible member through a first lumen of the catheter and, when the first moveable element is in the closed position, flow through the first lumen is prevented and a first biasing member coupled to the first flexible member for biasing the first moveable member toward the closed position.
Claims20
A valve comprising:
- a flexible member comprising a first moveable element, a second movable element, and at least one biasing member;
- wherein the first moveable element and the second moveable element are configured to move from a closed position to an open position when subjected to a fluid pressure greater than a predetermined threshold level;
- wherein the first moveable element and the second moveable element are configured to remain in the closed position when the fluid pressure is less than the predetermined threshold level;
- and
- wherein the at least one biasing member is configured to bias the first moveable element and the second moveable element towards the closed position.
