Methods and apparatus for surgical anastomosis

摘要

Methods and apparatus for anastomosis of a lumen according to various aspects of the present invention operate in conjunction with an impermeable stent. The impermeable stent may comprise a scaffold and, if needed, a sealant, such as a membrane and/or adhesive. In one embodiment, the scaffold, membrane and/or adhesive comprise biocompatible materials suitable for bio-absorption and/or degradation.

主权项

1. A method for prophylactically treating leakage of a lumen during anastomosis of separated ends of the lumen by providing an impermeable stent, comprising:
during a surgery, applying a sealant to an external surface of a scaffold; next, at least partially disposing the scaffold into separated ends of the lumen; attaching the scaffold to internal surfaces of the separated ends of the lumen via the sealant; and finally, attaching the separated ends of the lumen to one another after disposing the scaffold into the separated ends of the lumen such that the separated ends are in contact with one another.
