Abstract
A conduit assembly is provided for attachment to a Mechanical Circulatory Device (MCD) having an orifice surrounded by an orifice rim and a blood bag for forming a blood chamber in the MCD. The blood bag has an open end extends through the orifice. The conduit assembly comprises a tube, a coupling and a washer. The tube is provided for conducting blood between a patient and the orifice of the MCD. The tube has an orifice end. The coupling attaches the orifice end of the tube to the orifice of the MCD with the open end of the blood bag folded over the orifice rim of the MCD. The coupling is movable between a rotatable position wherein the tube is rotatable relative to the MCD, and a locked position wherein the tube is immobile relative to the MCD. The washer is placed between the orifice end of the tube and the blood bag folded over the orifice rim of the MCD. The washer has an inner section which has a shape corresponding to a space between the orifice end of the tube and the blood bag folded over the orifice rim of the MCD so as to smooth the transition between the tube and the blood bag at the orifice of the MCD to reduce turbulence in blood flowing between the tube and the blood bag.
