PROBLEM TO BE SOLVED: To provide a rapid exchange catheter wherein the length and shape of an inflated balloon can be adjusted in situ.SOLUTION: The rapid exchange catheter for permitting axial movement of an inner conduit within an outer conduit, includes: an outer conduit; an inner conduit, suitable for total or partial passage over a guide wire, wherein the inner conduit is disposed within the lumen of the outer conduit such that the longitudinal axes of the inner and outer conduits are substantially parallel, wherein the inner conduit is capable of being moved along its longitudinal axis in relation to the outer conduit, and wherein the proximal end of the inner conduit is angled such that it pierces the wall of the outer conduit; means for permitting the axial movement of the inner conduit within the outer conduit, such that the movement is not hindered by the passage of the angled proximal part of the inner conduit through the outer conduit; and means, situated at the proximal end of the outer conduit, for causing axial pushing-pulling movements of the inner conduit.
