ABSTRACT:
A dilatation catheter of the type having a balloon element adapted to be retracted by axial twisting following deflation is provided with a pair of concentrically related balloon twisting elements, one of which is adapted to be removed following full wind up of the balloon element so that the relative stiffness of the twisted balloon section of the catheter will be approximately the same as that of the balance of the catheter.
