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

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.

Abstract: Disclosed herein is an expandable introducer for a catheter. The expandable introducer generally includes an elongate, tubular body extending between a proximal end and a distal end along a longitudinal axis. The elongate, tubular body generally includes an inner layer, and an outer layer where the inner layer and the outer layer form a wall structure configured to radially expand and contract as a medical device passes along the axis. At least one of the inner layer and the outer layer includes an elastomer. In some embodiments, the expandable introducer includes a reinforcing strut sandwiched between the inner and outer layers to provide additional mechanical benefits.
