Abstract:
A system and method for producing a bioabsorbable thermoplastic polyurethane tailored to a medical application are provided. The method includes identifying suitable thermoplastic polyurethane properties based on the medical application. The thermoplastic polyurethane comprises units derived from a diol chain extender, a diisocyanate, and a polyol. The thermoplastic polyurethane properties include a biodegradation rate and at least one physical property. The method includes identifying a base thermoplastic polyurethane and altering at least one parameter of the base thermoplastic polyurethane which relates to the desired thermoplastic polyurethane properties to generate a candidate thermoplastic polyurethane. The altering may be performed iteratively until the suitable range of thermoplastic polyurethane properties based on the medical application is met.
