Abstract
A catheterization assembly comprises an elongate substantially cylindrical catheter having an outer surface, and a flexible collapsible guide element attached to the outer surface of the catheter at a distal end thereof. A guidewire extends generally parallel to the catheter and through the guide element so that the guide element is held in an extended guide configuration away from the outer surface.
