ABSTRACT:
A catheter introducer defines a tubular sheath with a housing on one end thereof, with the housing enclosing a fluid-filled, elastic-walled toroidal member defining a central aperture aligned with the tubular sheath axis. The central aperture is normally closed, being retained in the closed position by an elastic sleeve carried by the toroidal member. The central aperture is penetrable by a catheter in sealing manner as the catheter is advanced through the catheter sheath introducer.
