Methods of reducing retrograde flow
First Claim
1. A method of reducing retrograde flow across a valve within a body cavity comprising the steps of:
- a. an initial step of implanting a prosthetic valve having at least one leaflet comprising an extracellular matrix material and at least one aperture permitting retrograde fluid flow across the prosthetic valve;
b. permitting the implanted prosthetic valve to remain in the body cavity for a remodeling-effective period of time;
c. identifying the prosthetic valve within the body cavity comprising an aperture permitting retrograde fluid flow across the valve; and
d. implanting an occluding device after the remodeling-effective period of time, the occluding device comprising remodelable material in contact with the aperture of the valve within the body cavity to reduce the retrograde fluid flow across the valve.

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.
