Flower technique-A bailout technique to retrieve disrupted balloon catheters and stents.

We report two case series in which we encountered the difficulties to retrieve disrupted devices during percutaneous coronary intervention and endovascular treatment. The broken devices were successfully and safely retrieved by the "flower technique" that creates multiple cut and slit in the tip of the guiding catheter. This technique can be easily and safely applied in situations where a balloon catheter or stent has been disrupted and device entrapment has occurred, as the technique simply involves manually placing multiple cuts or slits in the tip of the guiding catheter. Transcatheter interventionists should be familiar with this technique because it can be bailout from device entrapment without additional cost or clinical experience.
