Abstract
A rotatable dilatation catheter comprising a pressure member formed by a coil of wire having open turns adjacent a distal end of the coil with the open turns being expandable to form a pressure member capable of obtaining various diameters. The enlargement of the diameter of the pressure member can occur by means of forming the member of an elastic material which will tend to expand, by means of applying a compressive axial force to the open turns to cause their radially expansion and/or applying a centrifugal force to the turns.
