  • Shape memory polymers and methods of use
    Patent number: 10532125
    Abstract: The presently-disclosed subject matter includes a compound comprising a first monomer, which is allyl-functionalized and crosslinkable, and a second monomer, which is not crosslinkable. In some embodiments the compounds are photocrosslinkable, and in certain embodiments are photocrosslinkable by ultraviolet light. Also provided are shape memory vascular grafts comprised the of present compounds that can transition from a temporary shape to an original shape when heated above a melting temperature of the graft. Still further provided are methods for treating vascular conditions that utilize embodiments of the present grafts.
