  • Publication number: 20230285188
    Abstract: The disclosure teaches methods of utilizing precisely engineered biodegradable drug delivery systems to treat intraocular conditions. In aspects, the disclosure provides methods of treating elevated intraocular pressure with intracameral implants administered to the anterior region of an eye. Furthermore, the disclosure provides for methods of lowering intraocular pressure in a subject, by administering intracameral implants that maintain a multi-month sustained level of travoprost acid in the aqueous humor of said subject’ eye, which is at least 8× lower than the EC50 values of travoprost acid on its molecular target, but yet still achieves clinically significant lowering of IOP.

  • Publication number: 20230094837
    Abstract: Embodiments relate to a crosslinked citrate-based elastomer catheter that is biodegradable and kink resistant. Embodiments of the crosslinked citrate-based elastomer material swells when surrounded by fluid (body fluid) so as to anchor the catheter to tissue but not anchor it so much that movement or removal will cause tissue damage. The catheter can be used as a component to a peripheral nerve block device, for example. Embodiments of the catheter can include embedding biodegradable sensors, moieties, shape memory material, etc. to monitor and modulate functions of the catheter and/or peripheral nerve block.
