Abstract:Minimally invasive interventional therapy started late, but it develops rapidly. The application of polymer materials in the production and preparation of minimally invasive interventional medical devices can effectively improve the therapeutic effect of clinical diseases. Based on this, the application of polymer materials in minimally invasive interventional medical devices is introduced, and polymer materials are generally divided into input materials and implant materials. The characteristics of polyether block amide copolymers, fluorine materials and polyimide materials as input materials are analyzed, and the application of expanded polytetrafluoroethylene, polyurethane, polylactic acid and other materials as scaffold materials is explored.The application of polymer materials with excellent performance can promote the development of minimally invasive interventional medical career.
Key words:Polymer materials; Minimally invasive intervention; Medical equipment; Biocompatibility
