METHOD AND DEVICE FOR DETECTING AND DETERMINING LOCATION OF ATHEROSCLEROTIC STENOSIS OF A BLOOD VESSEL Russian patent published in 1995 - IPC

FIELD: medicine. SUBSTANCE: method is applied by introducing a dielectric catheter into a blood vessel. In introducing the catheter electric resistance is measured for the segment between the electrodes spaced on the catheter to determine the existence of constriction from increased value of the electric resistance and to determine its location from the length of the introduced portion of the catheter corresponding to the maximum resistance. The accuracy in determining the constriction location is 1-2 mm. EFFECT: simplified examination method, higher accuracy of measurements. 3 cl, 3 dwg
