Abstract
Disclosed is an introducer apparatus comprising an sleeve fixation mechanism or introducer member, such as a catheter, introducer, or ring-like structure, which is attached to a protective sleeve comprising a thin flexible material such a polymeric film. The sleeve is inverted into the passageway of a second member, such as a catheter, feeding tube, introducer, etc., that is advanced through the passageway of the introducer member and is introduced into a bodily passage of a patient, such as the bile duct, nasal passages, colon, etc. The sleeve everts from the passageway of the 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.
