Abstract
A prosthetic check valve which allows unrestricted fluid flow in a forward direction and is capable of being repeatedly pulled open to allow reverse fluid flow. The valve comprises a valve body having an extensible section which houses a valve seat and a valve support. A resilient member is attached to the valve support and resiliently supports a valve member so as to force the valve member towards the valve seat. When the extensible section is contracted, the valve acts as a check valve to allow fluid flow only in a forward direction from a supply tube, through the valve support and valve seat, to a demand tube. When the extensible section is extended, fluid is allowed to flow both in the aforesaid forward direction and in a reverse direction through the valve.
