Abstract
A device which provides a measure of the compliance of a vessel wall based on a change in pressure, which causes the vessel to distend. The device comprises a coil and capacitor, forming a tank circuit. The coil is expandable and positioned along a portion of the vessel so that when the portion of the vessel expands or contracts, the coil will also expand or contract, changing the area in side the coil. This change in area alters the coil inductance, and therefore the resonant frequency of the tank circuit, which can be detected externally.
