We are developing a novel biodegradable, 3D-printed, polymeric implant utilizing a combination of different geometric shapes and composite structures to achieve quasi-linear release of biomolecules. This implant will be administered through minimally invasive injectable techniques. Relying on polymer degradation upon implantation, the Multistage Polymer Delivery System (MPDS) will provide customized biomolecule release dependent on the polymer combinations and implant geometries utilized.
