  • Publication number: 20160213812
    Abstract: A biodegradable bioprosthesis can include a biodegradable tissue and a biodegradable polymer combined with the biodegradable tissue. The biodegradable tissue can be non-crosslinked tissue, EDC crosslinked tissue or tissue crosslinked using biodegradable crosslinker. The biodegradable polymer can be a crosslinked polymer and/or synthetic polymer. The bioprosthesis can include a bioactive agent (rifampin). The biodegradable tissue and biodegradable polymer can form a drug delivery patch having the bioactive agent. The bioactive agent can be an antimicrobial. The biodegradable tissue can be decellularized. A method of making the biodegradable bioprosthesis can include treating the biodegradable tissue with a fluid having the biodegradable polymer. A method of implanting a biodegradable bioprosthesis can include implanting the bioprosthesis in a subject, where the bioprosthesis is implanted for repairing a hernia and/or the bioprosthesis inhibits post-operative adhesions.

  • Patent number: 9186422
    Abstract: Radio-opaque biodegradable compositions are formed by modifying terminal groups of synthetic and natural biodegradable polymers such as polylactones with iodinated moieties. The biodegradable property of the compositions renders them suitable for use in medical field such as drug delivery, imaging. Compounds disclosed in this invention exist as neat liquid. Certain compositions disclosed in this invention form hydrophobic iodine rich domains when dissolved in water, such domains provide better contrasting properties as well as ability to dissolve hydrophobic bioactive drugs. Certain iodinated moieties disclosed in the invention are capable of cross linking natural proteins in situ in presence of suitable catalysts and co-catalysts.
