In vitro evaluation of the calcification behavior of polyurethane biomaterials for cardiovascular applications.
Scope of the study is the calcification behavior of medical grade polyurethanes for cardiovascular devices.  Within these applications, implant material calcification is a serious complication.  The calcification behavior of these materials is investigated with a dynamic in vitro testing method for evaluating the influence of dynamic mechanical strain and parameters of the solubility of calcium salts.
