Making the volume of the arterial system increase elastically with blood pressure reduces high systolic blood pressure peaks. This volumetric elasticity is achieved by the action of a spring controlling the aortic cross-section thus controlling the aortic volume. The spring can be implanted percutaneously. The device is powered by the blood pressure itself and requires no other energy source or control circuits. The device can have an open structure or a sealed-wall structure, the latter also serve to protect against aortic aneurism. Non-linear volumetric elasticity can be used to assist the heart.
