Abstract
A measuring device is disclosed which includes a proximal end portion having an actuation member thereon and a distal end portion having an expandable member thereon wherein the actuation member and the expandable member are in mechanical or fluid communication via a lumen which extends therebetween such that actuation of the actuation member causes the radial expansion of the expansion member so that when the measuring device is placed in a puncture with the distal end portion in a blood vessel, the measuring device may be withdrawn until the expandable member contacts the wall of the blood vessel adjacent to the puncture to provide the user with an indication of the distance between and/or depth of the blood vessel beneath the skin of the patient.
