Graft vessel preparation device and methods for using the same

A graft vessel preparation device for preparing a graft vessel for a vascular anastomosis procedure, the preparation device comprising:

• a parallelogram linkage;
• a first spreader arm and a second spreader arm mounted substantially parallel to one another on opposing members of the parallelogram linkage, the spreader arms being movable with respect to one another by motion of the parallelogram linkage, the spreader arms being configured to receive an end of the graft vessel over the spreader arms and to move apart by action of the parallelogram linkage to establish a critical dimension on the graft vessel.

A preparation device for use with a graft vessel, comprising:

• spreader arms movable with respect to each other, wherein the spreader arms are adapted to receive the graft vessel;
• and
• a clamp rotatable with respect to the spreader arms, wherein the clamp is adapted to clamp the graft vessel received over the spreader arms and establish a critical dimension of the graft vessel.

A method for preparing a graft vessel using a graft vessel preparation device, the method comprising:

• forming an incision in a target vessel having an incision perimeter;
• and
• preparing the graft vessel by establishing and maintaining a critical dimension of the graft vessel such that the incision perimeter of the target vessel is substantially the same as a perimeter of the critical dimension of the graft vessel.
