The new design allows perfusion of fluids during total obstruction of the lumen by the introducer or a catheter with the designated sheath size. The new introducer is particularly useful for thrombolytic infusions and long-term use to reduce thrombosis. Also disclosed is a multi-port introducer sheath used for multicatheter placement. A larger version may be used for stent graft placement. Nothing filed to date.
