发明名称 CHEMICAL SUBSTANCE SUSTAINEDLY-RELEASING HOLLOW FIBER MEMBRANE
摘要 PROBLEM TO BE SOLVED: To provide a device having a chemical substance sustained-release function in the medical device for protecting a vascular channel from the outside of the vascular channel. SOLUTION: This chemical substance sustainedly-releasing hollow fiber membrane is characterized in filling micropores of the hollow fiber membrane with water-soluble polymer substance and supporting further the chemical substance in the hollow fiber membrane. A preferable mode of the hollow fiber membrane for protecting the vascular channel is formed into a tubular shape for covering the circumference of the narrowed vascular channel. Preferably, the water-soluble polymer substance is albumin or hyaluronic acid and the chemical substance is anticoagulant agent. COPYRIGHT: (C)2008,JPO&INPIT
