Title: DEVICES AND METHODS TO ASSIST IN LOCATING AN ARTERY AND GAINING PERCUTANEOUS ACCESS THERETO
Abstract:
A device (100, 200, 300) for identifying an arterial location includes a housing (110, 210, 310) with a tactile pressure sensor array (150, 250, 350) configured to detect pulsations of an artery once positioned over the presumed location of an artery. One of several LED lights (132, 232, 332) is energized to guide a clinician towards a preferred location of needle 10 insertion. The method of the invention comprises steps of positioning the device over the artery, reading pressure signals from individual pressure sensors, identifying peaks of pulsations and selecting the individual pressure sensor with the highest pulsation peaks as the closest to the artery located underneath. A corresponding LED light (132, 232, 332) is then activated to facilitate percutaneous access to the artery.
