Figure 1 A, The Cardica C-Port System. B, Close-up view of the C-Port cartridge and anvil. The anvil is 1 mm in diameter and has incorporated an arteriotomy knife. The cartridge contains 8 clips.

Figure 2 Main steps of loading the vein to the C-Port device at the toe (A) and the heel (B). The graft is incised on one side and inserted between the cartridge arms. The heel of the graft is then attached to 2 control spikes on the heel surface of the cartridge. The graft is then spread over the cartridge arms, and the toe of the graft is attached to the control spikes at the toe. The distal anastomosis can be done before or after the proximal anastomosis is completed.
