Abstract
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. A second and a third lumens are also included in the catheter body. The second and third lumens each have an open proximal 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.
