Coating of biomedical objects with microspheres obtained with biocompatible polymers

摘要

Provided is a process for coating the surface of a medical object or device, comprising adhering microspheres comprising a biocompatible polymer, a bioabsorbable polymer, or a mixture of a biocompatible polymer and a bioabsorbable polymer to said surface, wherein the mechanical characteristics of said medical object or device are unaffected by said coating. Such microspheres can be produced from total or partial esters of hyaluronic acid, and can contain pharmacologically active substances. These microspheres can be adhered with or without the use of an adhesive. Also provided are medical objects or devices coated with such microspheres.
