Abstract

The Palmaz-Schatz stent delivery system (PS 153) and "bare" PS 204 stents are relatively high-profile, rigid devices that can be difficult to deliver to lesions beyond tortuous, irregular, or rigid proximal segments. Described herein is a method of mounting and shaping a Palmaz-Schatz stent on a low-profile balloon that provides a steerable, low-profile, and secure stent delivery system. Also described is the successful use of this method in four consecutive cases where Palmaz-Schatz stents could not be delivered to the lesion site due to severely angulated, irregular, or rigid proximal vessel segments.
