  • a tubular portion, having a proximal end and a distal end, and a lumen extending from the proximal end to the distal end; and

    a retractable mechanism near the distal end of the tubular portion, the mechanism providing an increased cross section of the tubular portion when deployed and no increase or substantially no increase in cross section of the tubular portion when retracted;

    whereby the tubular portion is introduced into a vessel using either an antegrade or a retrograde approach and whereby the tubular portion can be repositioned within the vessel from an antegrade to a retrograde approach and from a retrograde to an antegrade approach without losing vascular access.
