Abstract
A device for measuring the intravascular diameter of an anatomical duct has a sheath encasing a catheter. One end of the catheter within the sheath has a sensor with a portion being biased radially outwardly relative to the sheath. Graduated visual indicia are disposed on the catheter near the other end of the sheath. When the sheath is inserted into an anatomical duct, the catheter is urged inwardly so that the sensor extends axially from the sheath and biased radially outwardly until it contacts the interior wall of the duct. At this point, the intravascular diameter can be read directly from the graduated visual indicia on the catheter.
