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. identifying a valve within the body cavity permitting retrograde fluid flow across the valve; and
b. implanting an occluding device comprising remodelable material in contact at least a portion of the valve within the body vessel 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.

12. A method of treatment, comprising the steps of:
-
a. implanting a prosthetic valve within a body vessel, the prosthetic valve comprising a remodelable material and at least one aperture in the remodelable material configured to permit retrograde fluid flow through the aperture;
b. permitting the prosthetic valve to remain in the body vessel for a remodeling-effective period of time; and
c. reducing the amount of retrograde fluid flow through the aperture after the remodeling-effective period of time. - View Dependent Claims (13, 14, 15, 16)
