Abstract
(A1) Die vorliegende Erfindung betrifft ein transdermales therapeutisches System zur steuerbaren Abgabe eines Wirkstoffes, insbesondere einer wundheilungsfördernden Substanz an eine chronische Wunde oder für die Chemotherapie mit zumindest einem Wellenleiter, wobei der Wirkstoff über eine durch elektromagnetische Impulse im Wellenleiter spaltbare Verbindung am Wellenleiter angelagert ist.

 

WO 2007131577 A2 UPAB: 20080310 NOVELTY - The transdermal therapeutic system has a wave guide. An active substance (4) is adsorbed at the wave guide over a connection that is cleavable by electromagnetic impulses in the wave guide. The wave guide is formed as a polymer fiber or as a polymer fiber composite. The wave guide is formed as a polymer coating, particularly as flat carrier foil, where the polymer coating is permeable to air. An optical based control system is provided for controlling of generation of the electromagnetic impulses for the proportioned release of the active substance. USE - Used for controllable release of an active substance, particularly for therapy directly to patients in chronic wounds or chemotherapy. ADVANTAGE - The transdermal therapeutic system has a wave guide, where an active substance is adsorbed at the wave guide over a connection that is cleavable by electromagnetic impulses in the wave guide and an optical based control system is provided for controlling of generation of the electromagnetic impulses for the proportioned release of the active substance, and hence makes possible controllable active substance dosage and minimizes total volume of delivered active substance with same therapeutic efficiency.
