Disclosed is an introducer apparatus (10) comprising a sleeve fixation mechanism or introducer member (12), such as a catheter, introducer, or ring-like structure, which is attached to a protective sleeve (13) comprising a thin flexible material such as a polymeric film. The sleeve is inverted into the passageway (22) of a second member (15 ), such as a catheter, feeding tube, introducer, etc., that is advanced through the passageway (20) of the introducer member and is introduced into a bodily passage (26) of a patient, such as the bile duct, nasal passages, colon, etc. The sleeve everts from the passageway of t he second member during its advancement to lay down a friction-reducing surface. The sleeve prevents frictional contact between the second member and delicate or sensitive tissues.
