Abstract
A flushable catheter device has an outer tube with a first distal end opening to be introduced into a blood vessel and defining a first lumen. An inner tube is disposed in the first lumen with a second distal end opening proximally spaced from the first distal end opening and defining a second lumen. A space axially disposed between the end openings defines an outflow/inflow inhibiting portion which inhibits a flow of fluid out from the first lumen into the into the vessel as a result of a perfusion of a flushing fluid being supplied through the first lumen and into the second lumen.
