ABSTRACT:
An implanted cardiovascular assist pump is connected with the proximal descending thoracic aorta. The pump inlet is connected with the aorta at substantially the site of the first pressure/flow node from the heart. The pump outlet is connected at substantially the site of the last pressure/flow antinode before the heart. Control of pump speed varies blood flow through the pump. As a fail-safe mechanism, a pump shunt flow path is provided, through one of a variety of disclosed structures.
