Abstract
A valve for use in a body lumen, where the valve includes a valve leaflet with delayed leaflet deployment relative an in vivo implant time. The valve includes a valve frame, a valve leaflet coupled to the valve frame. The valve leaflet includes a commissure that can reversibly seal for unidirectional flow of a liquid through the valve, and a biodegradable adhesive between the valve leaflet and the valve frame to hold at least the commissure of the valve leaflet in a static relationship relative the valve frame for a predetermined time once implanted in vivo.
