Abstract

Apparatus for measuring length in a blood vessel includes an inner barrel slideably fitting within an outer barrel. The apparatus also preferably includes a zero ring for initializing a position of the inner barrel relative to the outer barrel, wherein the zero ring is rotatably positioned on the outer barrel. The apparatus further includes a small-diameter clamp extending outwardly from the inner barrel for holding a catherization mechanism for visualizing a blood vessel, wherein the catherization mechanism includes a marker and a scale is positioned on the inner barrel for indicating a displacement of the inner barrel relative to the outer barrel in response to the catherization mechanism marker.
