ABSTRACT:
A sterile envelope-dispensing catheter introducer. A tubular introducer, through which a catheter is passed, dispenses a membranous shroud, or envelope, from within and out a distal opening thereof. The shroud is withdrawn by manipulation or by the urging of a body organ pressing against a shroud entrainment device. Interposition of the convolutionally rearward transported shroud over (and between) the introducer's distal portion (and the body internal organ surfaces) assures a sterile catheter passage through the introducer and into the organ.
