Method for inhibiting stenosis, occlusion, or calcification of a stented heart valve or bioprosthetic valve

摘要

The present invention relates to methods for inhibiting stenosis, obstruction, or calcification of a valve following implantation of a valve prosthesis which may involve disposing a coating composition which is a combination of two different drugs one to target inflammation and attachment of the target cell and the second drug to inhibit proliferation and calcification on an elastical stent, gortex graft or valve leaflet, the combination effect of the two drug therapies incorporated into the polymer to attach to the bioprosthesis will improve the efficacy of the inhibition of calcification and the improvement of the longevity of the prosthetic material including the stent, the valve, and the gortex covering. The valve prosthesis and or gortex graft is mounted on the elastical stent or prosthesis such that the elastical stent is in contact with the valve.
