George,
You're a bold man. I thought I had been pulling pretty hard! We had
a Cordis sheath in place and were unable to upsize to larger than 7 Fr
because that would have meant relinquishing the snare holding the stent
in order to have a sheath introduced over its dilator. What size sheath
did you have, and did it have any metal band at its tip to prevent
it from being turned into a reverse peel-away (splitting from its
leading tip?)
I now know (a detail omitted at the time) that partial pre-inflation
can give more body to the Diamond balloon allowing more secure
stent mounting; I'm not sure I need to learn new techniques to make a device
suit an application when there are other balloons that well without
event. I'm going back to PEMT, Olbert, and possibly the newer Cordis balloons that
are supposed to sustain higher pressures and allow repeated stent
mountings and introduction. Has anyone had experience with the Cordis balloons?
