A catheter assembly having a relatively stiff proximal portion bonded to a conformable distal portion with a first lumen extending through the proximal portion and through the distal portion. Also provided is a plurality of stylets each having a different preformed shape and each sized for insertion into the first lumen. Each stylet is effective to shape the distal end to a predetermined shape. Alternatively, the stylets may be received in a second lumen formed in a wall of the proximal portion and of the distal portion.
