Abstract

Una almohadilla de retorno dispersor para un procedimiento de ablación por radiofrecuencia incluye un material de piel adaptado para usarse en la piel del paciente, un material conductor posicionado adyacente al material de piel, un material no conductor que rodea el material conductor y un material de cambio de fase que rodea al menos una porción de un borde lateral del material conductor. Además, el material de cambio de fase se configura para sobrellevar una transición de fase en un rango de temperatura específico que corresponde a un rango de temperatura hipertérmico sin laceración para la piel del paciente. Como tal, el material de cambio de fase se configura para absorber el exceso de calor del procedimiento de ablación por RF y prevenir las quemaduras en la piel del paciente.
