The beneficial agent is applied into the holes in a medical device in a dry particulate form and is adhered in the hole in a manner that allows release of the drug in a controlled manner. The drug material would be formed into particles and placed in the holes. The solvent would be added to partially liquefy and adhere the drug into the holes. After application of the solvent, the particles are adhered together in a substantially uniform drug containing matrix. The particles may include drhug alone or drug in combination with other materials including a matrix.
L'invention concerne un procédé consistant à appliquer dans les trous d'un dispositif médical un agent bénéfique sous forme de particules sèches, et à faire adhérer celui-ci dans le trou de façon à permettre une libération contrôlée du médicament. Le procédé comporte les étapes suivantes: former la matière médicamenteuse en particules et la mettre dans les trous; ajouter un solvant pour liquéfier partiellement le médicament et le faire adhérer dans les trous. Après l'application du solvant, les particules collent entre elles de manière à former une matrice sensiblement uniforme contenant le médicament. Les particules comprennent un médicament seul ou en combinaison avec d'autres matières comprenant une matrice.
