摘要:
A catheter probe configured with a capability to present a larger tissue contact area or "footprint" for larger, deeper lesions, without increasing the french size of the catheter, especially its distal section, includes an elastically deformable electrode configured to adopt a neutral configuration and a tissue contact configuration. The deformable electrode comprising a hollow porous tube with a distal portion having a closed distal end, and a proximal portion defining an opening to an interior of the tube, where the distal tip end is received in the tube through the opening and the distal section is generally surrounded by tube, with the proximal portion being affixed to an outer surface of the distal section. In some embodiments, the closed distal end is shaped with a bulbous portion that can spread and widen to provide a larger surface contact area.
