A description is given of a catheter (1) which comprises at least one flexib le tubular catheter body (2) with a proximal end and a distal end, and an element interacting with the tubular catheter body, which element produces bending or stretching of the distal end by means of axial movement. Said element comprises a rigid shaping wire (4) wit h a predetermined intrinsic shape of at least the distal end, which wire is accommodated in the tubular body (2) and is slidable back and forth inside the tubular catheter body (2). The distal end of the tubular catheter body (2) also has a predetermined intrinsic shape. An axial movement of the shaping wire (4) produces a specific change of shape in at least the distal end of the tubular catheter body (2), the specific shape being determined by the intrinsic shape of the shaping wire when it is present in the distal end, or by the intrinsic shape of the tubular catheter body (2) in the absence of the shaping wire (4).
