u s patent application ser no 08 061 562 entitled 34 multi cell stent with cells having differing characteristics 34 which application is included herein by reference describes a stent which has at least three cells disposed circumferentially in each cylindrical segment of which the stent is composed fig1 shows a longitudinal cross section of a distal portion of a typical angioplasty balloon stent delivery catheter 10 which includes a stent 20 and a balloon angioplasty catheter 15 near the distal end of the balloon angioplasty catheter 15 is the angioplasty balloon 16 with folds 16a and 16b see fig2 the balloon 16 is attached at its proximal end to the distal end of the tube 11 and the distal end of the balloon 16 is joined to the distal end of the inner shaft 12 which has a inner guide wire lumen 19 through which the guide wire 30 can move slideably the annular passageway 17 between the tube 11 and the inner shaft 12 is in fluid communication with the space between the balloon 16 and the inner shaft 12 and is used to inflate and deflate the balloon 16 so as to expand the stent 20 into the wall of a vessel of the human body a radiopaque marker band 14 fixed to the inner shaft 12 provides a reference for identifying the center position of the balloon and stent fig2 is an enlarged transverse cross section of the catheter 10 at section 2 2 of fig1 the two balloon folds 16a and 16b of the balloon 16 are clearly shown during expansion of.
