Abstract
Abstract A stent delivery catheter system (10) employing a retractable protective sheath (50) for protecting a body lumen from the stent (55) as the stent (55) is being delivered by the catheter. The catheter (10) has a plurality of lumens (15,25,30), with at least one lumen (25) devoted to housing a rod, wire or hypotube (45) that retracts the protective sheath (50). The lumen (25) housing the retracting member (45) can carry a flushing fluid to purge the distal portion of the catheter (10).
