摘要： According to the present invention, a catheter having at least one multi-purpose lumen formed through the catheter terminates proximal a relatively complex-shaped distal portion thereof. In one form of this embodiment, the relatively complex-shaped distal portion comprises a looped portion having diagnostic- and/or ablation-type electrodes coupled thereto and an elongated diameter-adjusting member coupled proximal the distal end of the looped portion. The multi-purpose lumen may be used to alternately accommodate a variety of dedicated materials; such as, (i) a guide wire for initial deployment or later repositioning of the catheter, (ii) a volume or flow of a contrast media and the like, (iii) a deployable hollow needle or tube and the like used to biopsy adjacent tissue or dispense a therapeutic agent into a volume of tissue, and (iv) a cooling fluid, such as saline solution and the like dispensed at least during therapeutic tissue ablation procedures.
