Determinants of stent expansion in curved stenotic lesions: an in vitro experimental study.

Purpose: This study compared the expansion parameters of four different new-generation balloon-expandable stents in a curved stenotic phantom model.

Materials And Methods: Five stents for each length and type, each with a 3.5-mm diameter (AVE, 12 mm and 18 mm; Penta, 13 mm and 18 mm; BX-Sonic, 13 mm and 18 mm; and Jostent Flex Master, 12 mm and 16 mm), were implanted in curved silicon models 3.
