Abstract
A stent delivery catheter includes an extendable shaft portion, a tubular balloon mounted thereon, a stent and a pair of elastic retaining caps. The balloon is mounted onto the catheter at a mounted length that is shorter than the formed length of the balloon to generate excess balloon material which is gathered into circumferential folds. The extendable portion of the catheter shaft elongates in response to tension applied by the balloon as the folds open during inflation. Elongation of the catheter shaft drives the retaining caps apart to uncover the ends of the stent.
