An anastomotic device surgically joins the free ends of a first and a second tubular structure. The device generally includes two ring members, each of which is secured to a free end of the tubular structure. Each ring member includes an outer portion and an inner portion. The outer portions are each cylindrical and ring-like with open ends. The length of the cylindrical outer portions provides support for the portions of the tubular structures near and adjacent the ends of the tubular structure, thus reducing the likelihood of stricture during healing of the anastomotic tissue. Outer portions have holes around their perimeters which provide a scaffold for tissue to grow through for increasing the strength of the tissue near the anastomosis. The inner portions have connecting means and are designed to matingly engage one another. |
