Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
I claim: 1. A method of reducing retrograde flow across a valve within a body cavity, comprising: identifying a natural valve having a normal operation in which the valve permits fluid flow through said body cavity in a primary direction while substantially preventing fluid flow through said body cavity in the opposite retrograde direction, and having a leaflet defining a retrograde aperture in a portion of a leaflet surface area that permits retrograde fluid flow across the valve…
