Abstract
A guide for assisting in the cannulation of a patient comprising a flexible, tubular body having a hollow interior, a proximate end, and a distal end. The proximate end has an opening in communication with the hollow interior of the tubular body, and the distal end has a rounded, reinforced tip with a passageway therethrough which is in communication with the hollow interior. The guide is inserted and advanced to a position desired by the surgeon within a vein or artery, and then a cannula is threaded over the guide and advanced to the desired position before the guide is removed from the patient. The guide may be used in conjunction with a guide wire and/or a dilator.
