ABSTRACT:
A stent or support is disclosed for use in the connection or anastomosis of severed vessels to support and seal the anastomotic site. The stent includes substantially cylindrical sections separated by a tapered transitional region. The cylindrical sections are provided with flanges that define tapered sealing surfaces. The dimensions of the two sections are selected to correspond with the diameter of the portions of the vessel to be supported. The stent is preferably made of polyglycolic acid and the dimensions of the stent are selected to provide optimal support and sealing characteristics with a minimum of damage to the epithelial lining of the vas deferens. In two preferred applications, the stent is used in anastomosis of the severed ends of a vas deferens and a Fallopian tube. A gauge is used to measure the severed ends and, in that manner, determine the appropriate dimensions of the stent.
