  • Patent number: 9533001
    Abstract: Bioactive, hydroforming luminal liner compositions are formed of high molecular weight crystalline, absorbable copolyesters dissolved in a liquid derivative of a polyether glycol that undergoes transformation into a tissue-adhering, resilient interior cover or liner for the controlled release of its bioactive payload at clinically compromised conduits in humans as in the case of bacteria- and yeast-infected vaginal canals, esophagi, and arteries following angioplasty.

  • Patent number: 8951552
    Abstract: An in situ film-forming methyl acetate-based solution of at least one absorbable, segmented block copolymer with amorphous and semi-crystalline segments contains at least one bioactive agent which exhibits antimicrobial, anti-inflammatory, antiviral, anesthetic, hemostatic, and/or antineoplastic activity. The absorbable polymers can be a polyaxial copolyester, polyether-ester and polyether-ester urethane. The solution can be applied (e.g., sprayed or swabbed) onto animal and human skin or accessible body cavities to prevent or treat one or more disorders preventable or treatable by the bioactive agent therein.
