<p>An everting catheter system (11) comprising an outer catheter (13) having an outer catheter lumen (25) and an opening leading from the outer catheter lumen (25), an inner catheter (15) movable longitudinally in the outer catheter lumen (25) and having an inner catheter lumen (39) and an everting element (17) coupled to the outer catheter (13) and the inner catheter (15) so that with movement of the inner catheter distally in the outer catheter lumen (25), the everting element (17) can be everted through the opening. An elongated instrument (19) is movable longitudinally in the inner catheter lumen (25) relative to the inner catheter (15). Indicia (53, 55) are provided on the inner catheter (15) and the instrument for indicating at least one longitudinal position of the instrument relative to the distal end of the everting element (17).</p> |
