Double shape catheter

A catheter for delivering energy to a target location, wherein the catheter comprises:

• a catheter sheath having a proximal end and a distal end;
• a first structure having a proximal end and a distal end, and a second structure having a proximal end and a distal end;
• each of the distal ends of the first and second structures having a shape imparted thereto;
• each of the first structure and the second structure being adapted to extend from the distal end of the catheter sheath;
• and
• wherein the first structure and the second structure are displaceable between a first configuration and a second configuration, and wherein the first structure is distal relative to the second structure in the first configuration, and the second structure is distal relative to the first structure in the second configuration.

• each of the distal ends of the first and second structures having a shape imparted thereto;
• the second structure further comprising a fluid conduit disposed on at least a portion of an outer perimeter of the shape imparted thereto;
• each of the first structure and the second structure being adapted to extend from the distal end of the catheter sheath;
• and
• wherein the first structure and the second structure are displaceable between a first configuration and a second configuration, wherein the first structure is distal relative to the second structure in the first configuration, and the second structure is distal relative to the first structure in the second configuration.
