Abstract
Sistema transcatéter para la diferenciación entre tejido biológico normal, isquémico e infiltrado. Sistema de medida basado en un catéter que permite diferenciar entre tejido biológico normal, isquémico e infiltrado mediante la medida de la impedancia eléctrica de los tejidos en contacto con la punta de un catéter. El método se basa en los cambios de la impedancia eléctrica a diferentes frecuencias producidos por la alteración de los tejidos biológicos. Y así identifica tejido isquémico, cicatricial o infiltrado por células cancerígenas. En aplicaciones cardíacas el método permite, con la introducción del catéter en una cámara del corazón y su posicionamiento sobre una zona concreta del endocardio, la distinción entre tejido cicatricial, tejido isquémico, tejido valvular y tejido normal. Esta distinción es de especial interés al aplicar técnicas de ablación y mapeo endocardíaco. El catéter puede ser usado en otros órganos del cuerpo para la diferenciación entre tejido normal y tejido tumoral.
