Abstract

A catheter for ablating and imaging tissue includes a porous electrode structure comprising an interior region for receiving a conductive medium, and elongate tube having a distal tube end that extends within the interior region, and an ultrasonic transducer assembly housed within the distal tube end. The porous electrode structure includes an interior region that receives an ionic medium. RF energy can then be ionically transported through the pores within the electrode structure and into the tissue. The distal tube end and porous electrode structure are ultrasonically transparent, allowing the ultrasonic transducer assembly to image therethrough. The ultrasonic transducer assembly is sealed within the distal tubular end and is thereby isolated from the adverse corrosive and thermal effects of the ionic medium.
