Abstract

La divulgación se refiere a un catéter de ablación para la determinación de una propiedad local de un tejido biológico (50) con un vástago flexible (20), un equipo de tratamiento de datos (40) y un sensor RMN (30), que está dispuesto en el extremo distal del vástago (20) y unido con el equipo de tratamiento de datos (40), a lo cual el sensor RMN (30) presenta un primer elemento sensor (34) para la generación de un campo magnético estático y un segundo elemento sensor (35) para la generación de un campo magnético alterno, a lo cual el eje distal del vástago (20) está dispuesto de forma colindante con el punto a medir del tejido (50), a lo cual el equipo de tratamiento de datos (40) está ajustado para la determinación de la propiedad local del tejido (50) en ese punto basándose en una señal del sensor RMN (30) transmitida al equipo de tratamiento de datos (40). La divulgación también se refiere a un procedimiento correspondiente.
