Abstract:
1. An isolated graft material retaining a valve cusp shape for providing a valve cusp for contacting and modifying fluid flow in a body passageway, said isolated graft material prepared by a process comprising removing from a body cavity of a host a tissue material resulting from remodeling of a previously inserted amount of a remodelable extracellular matrix material in the body cavity, the remodelable extracellular matrix material being associated with an implanted shaping element in the body cavity and being effective, upon insertion in said body cavity, to stimulate the ingrowth of native cells into the remodelable extracellular matrix material such that the remodelable extracellular matrix material becomes infiltrated and replaced by newly formed host tissue, wherein said remodeling of said previously inserted amount of remodelable extracellular matrix material in association with said implanted shaping element causes said graft material to retain said valve cusp shape.
