Abstract

UN CATETER PARA BIOPSIA ENDOCARDIACA CONSTA DE UNA PARTE DISTAL DOTADA CON FORCEPS DE BIOPSIA (3) QUE INCLUYEN DOS MANDIBULAS (2,4) MOVILES UNA EN RELACION A LA OTRA ENTRE UNA POSICION ABIERTA Y UNA POSICION CERRADA, Y ELEMENTOS (15) ACCIONABLES DESDE EL EXTREMO PROXIMO DEL CATETER PARA MOVER LAS MANDIBULAS. LAS DOS MANDIBULAS DE LOS FORCEPS SON DE UN MATERIAL ELECTRICAMENTE CONDUCTOR, ESTAN AISLADAS ENTRE SI Y CONECTADAS RESPECTIVAMENTE A DOS TERMINALES SITUADAS EN EL EXTREMO PROXIMO DEL CATETER, DE FORMA QUE CUANDO LAS MANDIBULAS ESTAN EN SU POSICION ABIERTA PUEDEN UTILIZARSE COMO ELECTRODOS PARA IDENTIFICAR EL PUNTO DE ORIGEN DE UNA ARRITMIA VENTRICULAR. DE ESTA FORMA ES POSIBLE EFECTUAR UNA BIOPSIA ENDOCARDIACA EN PACIENTES APARENTEMENTE NORMALES CON ARRITMIA VENTRICULAR, TOMANDOSE MUESTRAS DE TEJIDO CORRESPONDIENTES A LA ZONA DE ORIGEN DE LA ARRITMIA Y EN CORRESPONDENCIA CON OTRAS ZONAS INMEDIATAMENTE DESPUES DE LA IDENTIFICACION DE LA ZONA DE ORIGEN. EN UNA VARIANTE, UNO DE LOS DOS ELECTRODOS ESTA FORMADO POR LAS DOS MANDIBULAS Y EL OTRO POR UN ANILLO SOPORTADO POR EL CUERPO DEL CATETER Y SITUADO COAXIALMENTE EN RELACION A ESTE.
