Abstract
(EN)
Embodiments of the invention include apparatus and methods for coating drug coated medical devices. In an embodiment, the invention includes a coating apparatus including a coating application unit. The coating application unit can include a fluid applicator having a lengthwise axis and a width. The fluid applicator can include a tip comprising a first face across the width of the fluid applicator. The first face of the fluid applicator can be oriented at an angle of from about 15 to about 75 degrees with respect to the lengthwise axis of the fluid applicator. The fluid applicator can define a second face intersecting the first face. The coating apparatus can further include a rotation mechanism and an axial motion mechanism. Other embodiments are also included herein.

Des modes de réalisation de l'invention concernent un appareil et des méthodes de revêtement de dispositifs médicaux revêtus de médicament. Dans un mode de réalisation, l'invention comprend un appareil de revêtement comprenant une unité d'application de revêtement. L'unité d'application de revêtement peut comprendre un applicateur de fluide ayant un axe longitudinal et une largeur. L'applicateur de fluide peut comprendre une pointe comprenant une première face sur toute la largeur de l'applicateur de fluide. La première face de l'applicateur de fluide peut être orientée selon un angle d'environ 15 à environ 75 degrés par rapport à l'axe longitudinal de l'applicateur de fluide. L'applicateur de fluide peut définir une seconde face croisant la première face. L'appareil de revêtement peut en outre comprendre un mécanisme de rotation et un mécanisme de mouvement axial. D'autres modes de réalisation sont également inclus ici.
