Abstract: A method of cancer hyperthermia therapy includes placing a device including an exogenously-excitable polymeric material at a cancer hyperthermia therapy site of a patient. The method also includes supplying an exogenous energy to the device such that the exogenous energy excites the exogenously-excitable polymeric material at the cancer hyperthermia therapy site to heat the cancer hyperthermia therapy site to a hyperthermia temperature. A method of preparing a polymeric material includes combining an alcohol monomer, a seed of the polymeric material, and an aqueous liquid in a vessel. The method also includes adding an acid monomer to the vessel and supplying an exogenous energy to the vessel. The polymeric material is exogenously excited by the exogenous energy to heat the polymeric material. The method further includes removing water from the vessel and producing the polymeric material, which is a polyester, in the vessel.

Abstract: A method of preparing a coated article includes providing an article and coating a surface of the article with a polymeric composition comprising poly(glycerol sebacate). In some embodiments, the composition is a poly(glycerol sebacate) copolymer.

Abstract: A process is provided for preparing a polymeric material through a water-mediated polymerization process that includes combining an alcohol monomer and an aqueous solution in a vessel, adding an acid monomer to the vessel, removing water from the vessel and producing the polymeric material from the vessel, wherein the polymeric material comprises a polyester of the alcohol monomer and the acid monomer. The methods described herein are particularly suitable for polymerization of poly(glycerol sebacate).

Abstract: The application is directed to aqueous dispersible biodegradable compositions of esters which are the condensation reaction product of a polyol and a diacid which are within a matrix of hydrated polypeptide. The compositions are useful in additive manufacturing and other applications for use with implantable articles. In some embodiments, the ester in the compositions is the product of a glyercol-sebacic acid condensation reaction.

Abstract: A composite hollow lumen and a method for producing the lumen are provided. The lumen includes a tubular textile formed of yarns having a first tensile strength and a matrix material in which the tubular textile is embedded to form a conduit having a bore and a sidewall substantially impermeable to liquid. The matrix material has a second tensile strength that is lower than the first tensile strength. The method for producing a composite lumen includes selecting yarns having a first tensile strength, selecting an elastomeric matrix material having a second tensile strength that is lower that the first tensile strength, forming a tubular textile of the yarns, and embedding the tubular textile in the matrix material to form a conduit having a bore and conduit walls that are substantially impermeable to liquid. The elastomeric matrix material is a biodegradable or bioresorbable polyester.
