<p>A de-jamming device (10) has a tubular housing (20) that defines a lumen (22) having a lumen axis (LA), a proximal end (24), and a distal end (26). The proximal end (24) has a threaded valve attachment (96) structure for threadedly attaching the de-jamming device (10) to the check valve (12). A portal (29) extends through the tubular housing (20) in communication with the lumen (22), and a push rod (30) is positioned through the portal (29) and into the lumen (22) such that the push rod (30) can be pushed into the valve conduit (82) for pushing open the sealing element (84) of the check valve (12).</p> |
