The retention element engages a luminal wall when the scaffold structure is expanded to retain the structure and exert a compressive force on the anastomosis. The mid portion has a greater radial stiffness than the lateral portions such that when the structure is expanded, the lateral portions engage tissue prior to the mid portion. The barrier layer is configured to engage a luminal wall when the structure is expanded to provide a fluidic seal at the anastomosis. The barrier layer may also include releasable biological agents to promote anastomotic healing. | 2010-01-28 |
