Method and apparatus for sealing end-to-end anastomosis

摘要

A cuff is used to provide a form for curing fluid about the exterior of an end-to-end anastomosis site. The cuff includes a port through which fluid may be injected to reach an interior space defined between the exterior of tissue at the anastomosis site and the inner surface of the cuff. A circular stapler may be used as a mandrel for the cuff and fluid. Alternatively, inflatable balloons may be used as a mandrel. The curing fluid may comprise a mixture of fibrin and thrombin.

1. A method of sealing an anastomosis site, wherein the anastomosis site is defined by the ends of two tubular anatomical structures, the method comprising:
(a) joining the ends of the two tubular anatomical structures together with a circular stapler, such that the ends of the two tubular anatomical structures are stapled together; (b) placing a cuff about the ends of the two tubular anatomical structures, wherein the cuff defines an interior space between an inner surface of the cuff and the exterior of the two tubular anatomical structures, wherein the act of placing the cuff about the ends of the two tubular anatomical structures is performed while the circular stapler is positioned at the anastomosis site, such that the circular stapler provides a mandrel for the cuff and the fluid in the interior space; (c) introducing a fluid into the interior space; (d) allowing the fluid to cure in the interior space to create a cured fluid seal; and (e) removing the cuff, leaving behind the cured fluid seal.
