Percutaneous coronary intervention
(PCI):

Is a non-surgical procedure used to treat the stenotic (narrowed)
coronary arteries of the heart found in coronary heart disease.


DREAMS is a balloon-expandable, paclitaxel-eluting scaffold on a
rapid-exchange delivery system.


DREAMS was optimized to provide a longer scaffolding time than its
predecessor and drug elution for inhibition of cell proliferation.

It is made of a magnesium alloy that is gradually absorbed. The
absorption process is complete after 9–12 months.

The scaffold strut surface is coated with a 1μm matrix of the
absorbable polymer carrier polylactic-coglycolic acid and the
antiproliferative drug paclitaxel.
