1. A device for indicating pressure variations due to systolic and diastolic phases of the cardiac cycle comprising:

  • (a) an elongated tubular member having a proximal end, a distal end and a lumen extending therebetween, the elongated tubular member including a port extending to the lumen proximate the distal end; and

    (b) an indicator device affixed to the proximal end of the tubular member, the indicator device including an elongated convoluted track formed therein, a transparent, fluid tight seal member covering said track, and a compliant sealing means positioned between said track and said lumen, the track containing a quantity of a liquid therein whereby the liquid reciprocally moves in said track under influence of systolic and diastolic pressure when the distal end is inserted through a puncture wound into a blood vessel.
