ABSTRACT:
An ablation catheter having self assembling large surface area distal component provided with one or more energy emitting surfaces for thermally destroying tissue. The distal component is oriented to present a compact, low profile for introduction into the heart, and after introduction is reconfigured to present a large surface area distal ablation tip assembly. The distal tip component is subsequently returned to the low profile configuration for removal from the heart. Once introduced, the energy emitting surfaces are thus carried by a distal component having significantly enlarged surface area. The enlargable distal component is produced using a plurality of pivoting sections capable of alignment into a compact profile for introduction into and removal from a living body. When reconfigured by pivoting of the sections into contact with each other, the distal component has an significantly enlarged dimension.
