Abstract
Abstract A rapid exchange stent delivery balloon catheter which allows exchange from a balloon angioplasty catheter to a stent delivery catheter without the need to replace the angioplasty catheter wire guide with an exchange-length wire guide before exchanging the stent delivery catheter for the balloon angioplasty catheter. The stent delivery catheter of the present invention includes a relatively short wire guide shaft which is bonded to the catheter shaft only at a location distal to the inflation lumen.
