SYSTEM AND METHOD FOR SCAFFOLDING OF ANASTOMOSES |
摘要 |
Embodiments of the invention provide systems and methods for using a tissue scaffold to facilitate healing of an anastomosis. One embodiment provides a tissue scaffold for placement at an anastomotic site within a body lumen comprising a radially expandable scaffold structure having lateral and mid portions, at least one retention element coupled to each lateral portion and a barrier layer. 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. |
