Abstract: A de-jamming device has a tubular housing that defines a lumen having a lumen axis, a proximal end, and a distal end. The proximal end has a threaded valve attachment structure for threadedly attaching the de-jamming device to the check valve. A portal extends through the tubular housing in communication with the lumen, and a push rod is positioned through the portal and into the lumen such that the push rod can be pushed into the valve conduit for pushing open the sealing element of the check valve.
