摘要:
A method for visualizing the interior of a bodily passageway comprising providing a system comprising a plurality of concentric telescoping shafts visualization apparatus disposed within the telescoping shafts and a helical thread disposed on the exterior of the telescoping shafts, the helical threads having a sufficient structural integrity and surface profile such that when the telescoping shafts are disposed in the passageway, rotation of the telescoping shafts induces a relative movement between the telescoping shafts and the passageway wherein the telescoping shafts are configured to be selectively coupled together and de-coupled from one another inserting the system into the passageway rotating the telescoping shafts so as to draw the passageway onto the telescoping shafts in a pleating fashion de-coupling the telescoping shafts rotating the innermost telescoping shaft so as to draw the passageway onto the innermost telescoping shaft in a pleating fashion and visualizing the interior of the passageway.
