Abstract
A single measurement tool is configured to measure at least two characteristics of a patient's vasculature during a surgical procedure such as a coronary artery bypass graft procedure. The measurement tool includes an indentation defined therein that is placed against a tubular structure such as the aorta to determine whether that tubular structure has a radius larger than or smaller than the radius of curvature of the indentation. The measurement tool may include a number of first recesses for measuring the diameter of a tubular structure. The measurement tool may include at least one second recess for measuring the wall thickness of a tubular structure.
