Catheter with internal mandrel and method

Abstract

Abstract A catheter (11) comprising an elongated, flexible catheter body (13) having a distal end portion which is curved in an unstressed condition. The catheter body (13) has a through lumen (31) and a mandrel lumen (33). A mandrel (15) is provided in the mandrel lumen (33), and the mandrel (15) has a distal end portion configured to at least partially straighten the curve of the distal end portion of the catheter body (13). The mandrel (15) is movable between an extended position in which the mandrel (15) at least partially straightens the curve of the distal end portion of the catheter body (13) and a retracted position in which the catheter body is more curved than in the extended position of the mandrel (15).
