An apparatus and method are provided for preparing a vein. A first tubular member end, defining a first lumen, is inserted into a cannulated vein, over a first guide wire. A second tubular member end, defining a second lumen, has a cutting member operably engaged therewith, and is inserted into the vein so as to intersect with and extend into the first tubular member, remotely to the first tubular member end, to establish communication between the first and second lumens, and such that a second guide wire received through the second lumen extends into the first lumen. Withdrawal of the first tubular member from the vein, over the first guide wire, causes the cutting member to longitudinally divide the first tubular member, from the intersection between the tubular members to the first tubular member end, to allow the second guide wire to pass through the division.
