摘要： A graft vessel preparation device and a method for using the graft vessel preparation device is provided. The graft vessel preparation device establishes and maintains a critical dimension on a graft vessel which corresponds to a dimension of an anastomosis site on a target vessel. One example of a graft vessel preparation device which prepares a graft vessel for a vascular anastomosis procedure includes a parallelogram linkage, a first spreader arm and a second spreader arm. The first spreader arm and the second spreader arm mount on opposing members of the parallelogram linkage in a parallel configuration. The spreader arms are configured in order to allow the placement of an end of a graft vessel over the spreader arms. The spreader arms are also configured to separate within an interior of the graft vessel once the graft vessel is placed over the spreader arms in order to establish a critical dimension. The critical dimension is established using a critical dimension locator. The critical dimension locator allows for precise grafting of the graft vessel to a target vessel during the vascular anastomosis procedure.
