Summary:The present disclosure is directed toward drug coated balloons, and in particular to drug coated balloons having a microcrystalline structure and techniques for increasing vascular permeability for drug application and retention. Particular aspects may be directed to a medical device including a balloon having an outer surface, and a drug coating layer on the outer surface of the balloon. The drug coating layer includes microcrystals in a haystack orientation having random and a substantial absence of uniformity in placement and/or angle on the outer surface of the balloon. La présente invention concerne des ballonnets revêtus de médicament, et en particulier des ballonnets revêtus de médicament ayant une structure microcristalline et des techniques pour augmenter la perméabilité vasculaire pour l'application et la rétention de médicament. Des aspects particuliers peuvent concerner un dispositif médical comprenant un ballonnet ayant une surface externe, et une couche de revêtement de médicament sur la surface externe du ballonnet. La couche de revêtement de médicament comprend des microcristaux dans une orientation de meule de foin présentant un caractère aléatoire et une absence substantielle d'uniformité de placement et/ou d'angle sur la surface externe du ballonnet.
