Abstract
DISPOSITIVO PARA MEDIR LA VELOCIDAD DE CIRCULACION SANGUINEA INTRACARDIACA QUE CONSTA DE UN CATETER (10) ADAPTADO PARA SU INSERCION EN UN VASO SANGUINEO (31) DENTRO DEL CORAZON Y AL MENOS DOS ELECTRODOS (12,13) HECHOS DE DOS DIFERENTES MATERIALES BIOCOMPATIBLES MONTADOS EN EL CATETER (10) EN UNA POSICION DE DETECCION EN EL AREA QUE SE DESEA INVESTIGAR (35) CUANDO DICHO CATETER (10) SE INTRODUCE EN EL CORAZON PARA DETECTAR LA VELOCIDAD DE CIRCULACION SANGUINEA. AL MENOS UNO DE DICHOS ELECTRODOS (PRIMER ELECTRODO 13) ESTA FORMADO COMO UN ELECTRODO POLARIZABLE Y SE COLOCA EN POSICION DE DETECCION, COLOCANDOSE EL OTRO (SEGUNDO ELECTRODO 12) DE FORMA AXIAL RESPECTO AL PRIMER ELECTRODO (13). LA VARIACION DE SOBREVOLTAJE O VOLTAJE GALVANICO SE UTILIZA COMO SEÑAL DE VELOCIDAD DE CIRCULACION SANGUINEA.
