Abstract
A cardiac assist catheter pump includes a displacement structure and a catheter. The catheter has an inlet in its distal end portion and an outlet spaced from the distal end portion. The displacement structure alternatingly applies suction for displacing fluid from the catheter to the displacement structure and pressure for displacing fluid from the displacement structure to the catheter. A valve body of the catheter is movable between an inlet position obstructing flow through the outlet and allowing flow through the inlet and an outlet position obstructing flow through the inlet and allowing flow through the outlet. Thus, a simplified construction and a reduced risk of blood clotting is achieved. A catheter and a fitting for such a catheter pump are also described.
