ABSTRACT:
A device and method for measuring fluid flow within a vessel having fluctuating elastic walls, such as, for example, an artery. The device includes a catheter; an internal stablizer or frame for establishing an invariant cross-section in the vessel wall; and a fluid velocity detecting system, such as, for example, a Doppler crystal transducer. The method for measuring includes the steps of stabilizing the vessel wall and measuring the velocity of fluid passing through the stabilized cross-section of the vessel wall. A method of treating and a method of diagnosing vascular disease by employing the device of this invention is also part of the invention.
