FLOW REDUCTION CATHETER FOR FLUID OVERLOAD TREATMENT

Disclosed herein is a vessel shaping device configured to reshape a vessel along a single axis and regulate a blood flow therethrough. The vessel reshaping device generally consists of a frame that can transition to an expanded configuration and can temporarily reshape a vessel, e.g. the inferior vena cava ("IVC"), in a single axis extending perpendicular to a longitudinal axis. The greater the expansion of the reshaping device, the greater the reduction in cross-sectional area and the greater the reduction in flow through the vessel. Modifying a blood flow to the heart as such can improve the symptoms of hypervolemia, leading to increased diuretic efficiency and improve symptoms of congestive heart failure.
