Title
(EN) USE OF NANOCRYSTALS FOR A DRUG DELIVERY BALLOON
(FR) UTILISATION DE NANOCRISTAUX POUR UN BALLONNET DE DISTRIBUTION DE MÉDICAMENT
Abstract
(EN)
A drug delivery balloon (10) has a drug thereon in the form of crystalline particles (12), the drug having a predetermined size distribution. Optionally marker particles (14, 16) are also provided. A texturized coating (18), a cap layer (20) and/or other methods may be used to increase particle loading capacity of the balloon.
(FR)
L'invention porte sur un ballonnet de distribution de médicament (10) qui contient un médicament se présentant sous la forme de particules cristallines (12), le médicament ayant une distribution granulométrique prédéterminée. Des particules de marqueur (14, 16) sont également facultativement prévues. Un revêtement texturé (18), une couche d'encapsulation (20) et/ou d'autres procédés peuvent être utilisés pour accroître la capacité de chargement en particules du ballonnet.
