Abstract
Apparatus and methods for dilating a vessel or organ, especially a larger diameter vessel or organ, are provided using a catheter having a balloon element is disposed within a sheath having an expandable but non-compliant mesh region covering the balloon element. The sheath is selected from among a plurality of sheaths each having a mesh member that is expandable to a different predetermined expanded diameter, the mesh region preventing the balloon member from developing bulges during inflation and constraining the edges of the balloon from perforating the vessel in the event of perforation. The sheath, which extends to a proximal end of the catheter, is also employed to reduce the diameter of the balloon member following the dilatation procedure, thereby preventing the balloon from bunching up in the vessel or organ.
