Claim 0:
1. An introducer sheath assembly comprising:
a tubular sheath body having a proximal end, a distal end, an outer surface, and an inner surface, the inner surface defining a lumen between the proximal and distal ends for passage of a catheter device;
a balloon sleeve having an inflatable balloon, the balloon sleeve configured to surround and slide over a portion of the catheter device for insertion into the lumen of the tubular sheath body such that the inflatable balloon forms a fluidic seal between the inner surface of the tubular sheath body and the catheter device when the inflatable balloon is inflated, the fluidic seal being configured to form a region in which fluid is prevented from flowing between the tubular sheath body and the catheter device.
