Claim:
1. A catheter comprising: an elongate catheter body defining a first lumen and a second lumen each longitudinally extending between a proximal end and a distal end of the elongate catheter body and including a first lumen opening and a second lumen opening, respectively, in the distal end; a wire including a first segment and a second segment each having a greater stiffness and slidable in opposed directions through the first lumen and the second lumen, respectively, and a middle segment having a lesser stiffness; and the wire being in an elastically deformed access state where the middle segment extends from the first lumen opening to the second lumen opening and forms a smaller loop projecting from the distal end, and being adjustable via a sliding to an elastically deformed treatment state where the first segment extends from the first lumen opening to the second lumen opening and forms a larger loop projecting from the distal end.
