Abstract
In surgery, especially in microsurgery, the joining of blood vessels or tubular organs, anastomosis, consumes a considerable part of the surgical time. This invention provides fasteners that are shaped in such a manner that they are retained in a novel clamping device until the joining is accomplished. The fasteners comprise at least two couplable rings having axially directed pins and intermediate holes distributed about their centers, and a shoulder portion formed along the periphery of at least one of the rings for fitting at least one of the rings into the clamping device.
