Abstract

The present invention relates to a composite and a method for reducing post-operative adhesion of tissues. The composite includes a biocompatible, biodegradable support, and a water-insoluble hyaluronic acid derivative at the support. The hyaluronic acid derivative includes an N-acylurea that results from cross-linking by the reaction of hyaluronic acid with a multifunctional carbodiimide. Optionally, a monocarbodiimide also may be employed. A pharmaceutically-active molecule may be added to the N-acylurea derivative of hyaluronic acid. Although the composite includes material that prevents adhesion between tissues, in order to reduce the need for suturing when the composite is being used during a surgical procedure, a material that enhances adhesion of the composite to tissues may be applied to a surface of the composite. A method of forming the composite for reducing post-operative adhesion of tissues, including the step of applying an N-acylurea derivative of hyaluronic acid resulting from cross-linking with a multifunctional carbodiimide, to a biocompatible, biodegradable support; a method of preparing a drug delivery vehicle that includes a pharmaceutically-active molecule with the N-acylurea derivative of hyaluronic acid resulting from cross-linking with a multifunctional carbodiimide; and a method of reducing post-operative adhesion of tissues are disclosed.
