摘要:A method and implantable device for measuring blood flow through a bloodvessel within human or animal bodies utilizes the principle of energy conversion to heatby myocardial activity, organ metabolism, and laminar frictional flow in blood vessels, andmeasures the heat dissipation through the vessel wall with obstruction to flow. Thedevice, which comprises a support sheath (10) having a thermocouple (16) or thermistorembedded therein, is placed next to the vessel wall. An output signal from the sensor(16) correlates blood flow with temperature. With an obstruction to flow, the
temperature drops. Two sensors (16) placed in series, proximal and distal to a repairedvessel are connected transcutaneously to a temperature monitor and detection of atemperature difference is indicative of an occlusion at the repair site.
