  • BIODEGRADABLE POLYCAPROLACTONE CAPSULE FOR ANTIBODY RELEASE AND DEGRADATION
    Publication number: 20230355533
    Abstract: A biodegradable capsule implant is provided. The biodegradable capsule includes a capsule body having an inner surface and an outer surface. The capsule body includes a polymer, and the inner surface defines a hollow interior space. The biodegradable capsule further includes a therapeutic agent housed in the hollow interior space. The biodegradable capsule further includes a plurality of pores on the capsule body. The capsule body is configured to absorb the therapeutic agent at the inner surface and desorb the therapeutic agent out of the outer surface.

  • SIZE-EXCLUSIVE DOSE-CONTROLLABLE DRUG DELIVERY IMPLANT
    Publication number: 20230069429
    Abstract: An implant device includes a polymer tube including an enclosed inner space, and a mixture of a hydrogel and a plurality of nanoparticles within the enclosed inner space. Each of the plurality of nanoparticles includes a shell, payload within the shell, and one or more photothermal agents on a surface of the shell. A wall of the polymer tube includes one or more layers of nanoporous polymer sheets including a plurality of pores. The dimension of the nanoparticles is greater than the dimension of the pores, and the dimension of the payload is smaller than the dimension of the pores.
