  • Patent number: 9545447
    Abstract: The present disclosure generally relates to polymer-drug systems, and more particularly to nanoscopic particles comprising amphiphilic block copolymers conjugated, physically encapsulated, or otherwise combined with chemotherapeutic agents along a selective region or regions of the backbone of the copolymer, so as to package the chemotherapeutic agent in selective domains within each nanoscopic particle, as well as to methods for making such particles, and applications and methods for using such particles, including in the formation of polymer micelles.

  • Publication number: 20160317796
    Abstract: In accordance with the invention, compositions, devices, and related methods have been developed for medical-related and other applications. In some embodiments, the devices and compositions described herein comprise a triggerable shape memory polymer network. In certain embodiments, the polymer network comprises a covalently crosslinked polymeric material and a non-crosslinked polymeric material associated with the crosslinked polymeric material. In some cases, the polymer network has a first configuration (e.g., as polymerized), and a second configuration (e.g., upon heating and deformation), such that the polymer network can be triggered to recover the first configuration upon heating the polymeric material above a softening temperature of the polymeric material. In certain embodiments, the polymer network comprises a plurality of particles capable of increasing the temperature of the polymer network (e.g.
