ABSTRACT:
A catheter device regulates fluid flow within a circulatory vessel. Included is an elongated catheter body configured to access one of a circulatory vessel or a heart chamber. The catheter body includes a proximal end, a distal end, and a first lumen including an open proximal end and a distal end with a port formed at a distal portion of the distal end. An antegrade valve is coupled to an exterior of the catheter body and configured to provide a controllable antegrade flow and a controllable retrograde flow along the exterior of the catheter body. The antegrade flow is greater than the retrograde flow. A retrograde valve may be included which provides a controllable retrograde and antegrade flow along the exterior of the catheter body. When a retrograde valve is used, the retrograde flow is greater than the antegrade flow.
