摘要：A highly automated device to measure the impedance to fluid flow of a vesselby means of direct injection at normal physiologic pressures. The device producesobjective impedance data including dynamic impedance, capacitance, and Direct Currentresistance, without operator induced error. The device can be used for intraoperativeimpedance measurements by directly cannulating the vessel under study. Non- operativeimpedance measurement is performed by means of percutaneous catheters. The devicecan also inject imaging materials or a lytic solution into the vessel while also measuringvessel impedance.
