A peel-away introducer cannula having a sheath tube, cannula hub, and peel-away blood flow reducing valve to prevent backflow of blood is provided. The sheath tube is weakened along opposed axial lines to allow for the sheath tube to be split in two. Similarly, the cannula hub is weakened along opposed axial lines, which align with the opposed axial lines in the sheath tube. The blood flow reducing valve is disposed within the cannula hub, wherein the blood flow reducing valve is also weakened along opposed axial lines, which align with the weakened opposed axial lines of the sheath tube and said cannula hub. Optionally, a splittable handle is attached to the hub such that the handle may be split and drawn apart to split the sheath tube, blood flow reducing valve, and hub along the weakened axial lines. Methods of introducing a vascular device are similarly provided.
