Abstract
Methods of reducing retrograde fluid flow through a valve within a body vessel are provided. The methods can include the steps of identifying a valve exhibiting an undesirable amount of retrograde fluid flow within a body vessel, such as a venous valve or a heart valve, and providing a means for reducing the retrograde fluid flow. A medical device providing a desired amount of retrograde fluid flow can be modified after permitting the medical device to remain in a body cavity for a remodeling-effective time period. The implanted medical device can be modified by subsequently reducing the amount of retrograde fluid flow permitted across the implanted prosthetic valve within the body vessel.
