Medical devices for implantation within a body vessel can include a remodelable material, such as an extracellular matrix material, positioned within a lumen defined by an outer covering material. The covering material is preferably substantially non-remodelable, and can be supported by a radially expandable frame. The medical device can also include a valve means positioned within the covering material. The valve means can include one or more valve leaflets formed from the remodelable material, and a separate valve support frame. One or more therapeutic agents can be associated with the remodelable material or the covering material.
