Abstract
A catheter ( ), and a method for performing radiation treatment at a site where angio-plasty was performed, are disclosed. The catheter ( ) includes a hollow, cylindrical member ( ) constructed from a fairly flexible material. The catheter is maneuvered within the body by traveling over a guide wire which was initially maneuvered in the blood vessel to a position beyond the actual site of a stenosis. Stand-off structure ( ) having a stand-off balloon ( ) surrounds a portion ( ) of the outer surface of the catheter ( ). The distal end ( ) of the catheter ( ) includes an inner lumen plug ( ), and a distal mandrel ( ) extending through the inner lumen plug ( ). The distal mandrel ( ) is manufactured from shape memory alloy to stiffen, and reinforce the catheter when the catheter is introduced within the blood vessel.
