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;

    providing an occluding device comprising a remodelable material;

    implanting the occluding device in contact with at least a portion of the natural valve to block fluid flow through the retrograde aperture.
