Introducer sheath assembly for catheter systems and methods of using same

Abstract

A catheter system includes a catheter including an elongate body having an expandable medical device coupled with a distal end thereof, and an introducer sheath assembly disposed over a proximal section of the catheter. The introducer sheath assembly includes an introducer sheath disposed over the catheter to form a gap therebetween, and a tubular plug. The introducer sheath includes an elongate body extending from a proximal end to a distal end and defining a lumen therein. The tubular plug extends through the lumen and includes an elongate body extending from a proximal end to a distal end that protrudes from the introducer sheath distal end. The plug is disposed between the catheter and the introducer sheath to occlude the gap. The plug is releasably fixed relative to the introducer sheath such that the plug is removable from the lumen to allow the expandable medical device to pass therethrough.
