Closed disposable seeding systems with improved seeding chambers permitting uniform seeding of a scaffold or graft with patient's cells are provided. The seeding chambers with a variable width along the length of the chamber, or a minimal gap between the scaffold and chamber wall, provide an improvement of the prior seeding chambers of closed disposable seeding systems by providing faster and more efficient and uniform seeding of the grafts and scaffolds. Also described are scaffolds with biomechanical and structural properties permitting spontaneous reversal of stenosis and neotissue formation as the graft degrades yielding a scaffold-free neovessel.
