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.
An introducer apparatus for providing a reduced-friction pathway into a bodily passage of a patient, comprising:
An introducer apparatus for providing a reduced-friction pathway into a bodily passage of a patient, comprising:
An introducer apparatus for providing a reduced-friction pathway into a bodily passage of a patient, comprising:
An arrangement for locating an elongated member within a bodily passage of a patient, wherein at least a substantial part of a flexible sleeve is to be movably located within the elongated member, wherein means are provided for fixing another part of the sleeve at a location outside of the elongated member so that when the latter is moved in a distal direction, a distal part of the elongated member engages the sleeve and unfurls it between the outside surface of the elongated member and the inside of the bodily passage.
A method of reducing frictional effects when introducing an elongated member having a passageway into a bodily passage, the elongated member comprising a flexible sleeve with a substantial length of the sleeve disposed in the elongated member and with a part of the sleeve fixed at a location outside of the elongated member, so that when the elongated member is moved in a distal direction, a distal part thereof engages the sleeve and unfurls it between the elongated member and the bodily passage, the sleeve being adapted such upon unfurling from within the passageway of the elongated member, the passageway is at least substantially open.
