1. A device that allows a user to calculate the length and diameter of a suitable interventional prosthesis as well as the height and length of stenosis during the same exploratory procedure, the device comprising:

  • an exterior conduit longitudinally extending between proximal and distal ends, the exterior conduit having measurement markers formed on a portion thereof;

    an interior conduit longitudinally extending between proximal and distal ends, disposed within the exterior conduit, and displaceable with respect to the exterior conduit, the interior conduit having a depth marking mechanism visible through a portion of the exterior conduit;

    a measurement assembly comprising at least two legs having distal and proximal ends and inward facing and lumen facing surfaces, the legs coupled with each other proximal the distal ends thereof, the measurement assembly also coupled about the distal end of the interior conduit;

    a handle operatively connected with the measurement assembly, the handle comprising a means for opening and closing the measurement assembly by actuating the handle along a continuum between a first closed configuration and a second open configuration.
