  • Publication number: 20240009116
    Abstract: The invention is describing an intrauterine delivery system comprising non-steroidal anti-inflammatory (NSAID) and a progestogenic compound, containing anti-inflammatory active compound in the frame material and that the progestogenic compound is contained in a silicon based reservoir attached to the frame, wherein the frame consist of a thermoplastic material. A further object of the invention is to fabricate drug-containing T-intrauterine systems (IUS) with the drug incorporated within the entire backbone of the medical device by using 3D printing technique, based on fused deposition modelling (FDM™). Indomethacin was used to prepare drug-loaded poly-caprolactone (PCL)-based filaments with different drug contents 5-40 wt %, namely 5%, 15% and 30% wt %:of Indomethacin.

  • Patent number: 11666552
    Abstract: The present invention relates to a method for modifying release of a therapeutically active agent from an elastomeric matrix, comprising providing a core comprising an elastomeric matrix and a therapeutically active agent; dipping the core to a coating solution of an elastomer, wherein the elastomer comprises 20-35 wt-% of a filler, calculated from the total amount of filler and elastomer; curing the dipped core to provide a coated core. In this method the dipping is provided as a continuous process by pulling the core through the coating solution, using a pulling speed suitable for providing a coating thickness of ?-IOO the filler is selected from silica, titanium dioxide, barium sulphate, carbon and mixtures thereof; the elastomer comprised in the core and the elastomer comprised in the coating solution are independently selected from poly(dimethyl) siloxanes, polyethylene vinyl acetates (EVAs), polyurethanes (PUs), polyhydroxyethyl methacrylates (PHEMAs) and polymethyl methacrylates (PMMAs).

  • Patent number: 6136268
    Abstract: A method for determining the concentration of a light-emitting compound. An electric pulse is applied to a pair of current-delivering electrodes immersed in an electrolyte having positioned between the electrodes a conductor not in electronic contact with electrodes. As a result of the applied electric pulse, the light-emitting compound in electronic contact with the conductor luminesces in which the emitted light is measured and used to quantify the light-emitting compound.
