Abstract
Devices and methods are disclosed for the control of blood perfusion pressure within a blood vessel that undergoes arterialization. A cannula is introduced that contains a stenosis that either resorbs or is removed in time, allowing a gradual increase in blood pressure between two blood passages connected at either ends of the cannula. Particular emphasis has been made with the use of the cannula for the vessels in the heart.
