Abstract:
A catheter has a multifunctional “virtual” tip electrode with a porous substrate and a multitude of surface microelectrodes. The surface microelectrodes are in close proximity to each other and in a variety of configurations so as to sense tissue for highly localized intracardiac signal detection, and high density local electrograms and mapping. The porous substrate allows for flow of conductive fluid for ablating tissue. The surface microelectrodes can be formed via a metallization process that allows for any shape or size and close proximity, and the fluid “weeping” from the porous substrate provides more uniform irrigation in the form of a thin layer of saline. The delivery of RF power to the catheter tip is based on the principle of “virtual electrode,” where the conductive saline flowing through the porous tip acts as the electrical connection between the tip electrode and the heart surface. The substrate and the surface electrodes are constructed of MRI compatible materials so that the physician can conduct lesion assessment in real time during an ablation procedure. The surface electrodes include noble metals, including, for example, platinum, gold and combinations thereof.

Claim (Index 1):
A catheter comprising:\n an elongated catheter body; a distal electrode member having a porous substrate and a plurality of surface electrodes on portions of an outer surface of the porous substrate, the porous substrate having an interior chamber adapted to receive conductive fluid; a plurality of lead traces on an outer surface of the porous substrate, each of the plurality of lead traces connected to a respective one of the plurality of surface electrodes, at least one of the plurality of lead traces having a portion extending underneath at least one other of the plurality of surface electrodes, the portion of the at least one of the plurality of lead traces extending underneath the at least one other of the plurality of surface electrodes sitting in a groove on the outer surface of the porous substrate; and a chamber lead wire having a distal portion extending into the interior chamber, the chamber lead wire adapted to electrify the conductive fluid in the interior chamber, the porous substrate being configured to pass the conductive fluid from the interior chamber to the outer surface of the porous substrate.
