ABSTRACT:
A catheter comprising an elongated, flexible catheter body having a distal end portion which is curved in an unstressed condition. The catheter body has a through lumen and a mandrel lumen. A mandrel is provided in the mandrel lumen, and the mandrel has a distal end portion configured to at least partially straighten the curve of the distal end portion of the catheter body. The mandrel is movable between an extended position in which the mandrel at least partially straightens the curve of the distal end portion of the catheter body and a retracted position in which the catheter body is more curved than in the extended position of the mandrel.
