Abstract:
A stent delivery catheter, the catheter comprising:a catheter shaft, and a balloon, the balloon being mounted to the catheter shaft, the balloon when unconstrained being inflatable to a first inflation state at a first pressure where the balloon is nominally inflated by unfolding without substantial expansion and to a second inflation state at a second pressure higher than the first pressure, the balloon having a stent mounting region, at least one adjacent region, and at least one cone region, the at least one adjacent region being positioned between the stent mounting region and the at least one cone region, the stent mounting region having a stent mounting region inner diameter and the at least one adjacent region having an adjacent region inner diameter; wherein when the balloon is in the first inflation state the stent mounting region inner diameter is less than the adjacent region inner diameter, and when the balloon is in the second inflation state the stent mounting region inner diameter is substantially the same as the adjacent region inner diameter.
