20090117170 | SEGMENTED DEVICE FOR THE DELAYED RELEASE OF MOLECULES IN A TANGENTIAL DIRECTION THROUGH THIN FILMS AND USES THEREOF - The present invention of a segmented release device (sandwich construction with reservoir) for molecules (active compounds, medicaments, diagnostic, therapeutic and chemical reagents) is based on a construction which makes possible a constant release rate through diffusion-permeable intersegment films partially or completely filled with liquid of the neighboring media. The molecules pass here from the reservoir of the device into the outer medium by diffusion exclusively through the intersegment films. These intersegment films are adjustable in their thickness and composition in the manner specified in each case. | 05-07-2009 |
