Patent number: 10940229Abstract: A material for adhesion prevention can be adhered to biological tissue with certainty and has improved tissue adhesiveness and biodegradability. Such material for adhesion prevention is composed of: a 1- to 1,000-?m-thick water-soluble support layer comprising a water-soluble polymer; and a 1- to 1,000-?m-thick adhesion prevention layer comprising a biodegradable polymer. The biodegradable polymer has a structure in which a branched polyalkylene glycol comprising 3 to 8 terminal hydroxyl groups per molecule is bound to a polyhydroxy alkanoic acid, and a mass ratio of the branched polyalkylene glycol relative to the total mass is 1% to 30%.Type: GrantFiled: September 29, 2017Date of Patent: March 9, 2021Assignees: Toray Industries, Inc., Nanotheta Co., Ltd.Inventors: Akihiro Saito, Megumi Nakanishi, Kazuhiro Tanahashi, Toru Arakane, Motonori Hochi, Ai Suzuki, Koji Okabayashi, Shinji Takeoka, Toshinori Fujie, Yuya Ishiduka, Shinya Ohtsubo

Patent number: 10786980Abstract: A laminate has at least one polylactic acid resin-containing layer (C) with a thickness of 10-500 nm on at least one surface of a fibrous structure (B) containing a water-soluble resin (A). A production method for the laminate is characterized in that water or an aqueous solution is applied to the joining surface of the fibrous structure (B) and the polylactic acid resin-containing layer (C). The laminate exhibits excellent followability, adherence and coatability relative to flexible, curved adherends, exhibits excellent compatibility to organs such as skin and internal organs, and, because the fibrous structure (B) containing a water-soluble resin (A) can easily be removed from the polylactic acid resin-containing layer (C) by the aqueous solution, is adapted for use in materials for external use on the skin, such as wound-dressing materials, adhesion-preventing materials, and skin care products.Type: GrantFiled: June 18, 2015Date of Patent: September 29, 2020Assignee: Toray Industries, Inc.Inventors: Yuki Sekido, Motonori Hochi, Toru Arakane, Yoshikazu Yakake, Teruhisa Sato

Patent number: 10531988Abstract: A laminated film includes a polylactic acid-based resin layer and one or more acetylated hyaluronic acid layers laminated on a side of the polylactic acid-based resin layer, is highly flexible and easy to handle and, when stuck to an adherend with curved surface, the laminated film has excellent followability, adhesiveness and coating properties to the adherend, since the acetylated hyaluronic acid layer(s) can be removed easily with an aqueous solution from the polylactic acid-based resin layer in a thin film shape. The acetylated hyaluronic acid and the polylactic acid-based resin are biodegradable and, therefore, the laminated film is highly compatible with skin and organs such as visceral organs. The laminated film is optimally usable as a dermal material for external application such as a wound coating material, an adhesion inhibitor and skin care articles.Type: GrantFiled: December 4, 2015Date of Patent: January 14, 2020Assignees: Toray Industries, Inc., NANOTHETA CO, LTD.Inventors: Motonori Hochi, Yuki Sekido, Akihiro Saito, Shinji Takeoka, Shinya Ohtsubo, Akinari Hinoki, Manabu Kinoshita
