Abstract:
1. An assembly comprising: an introducer sheath having a passageway extending longitudinally therethrough, said introducer sheath comprising a tubular proximal segment and a tubular distal segment; said tubular proximal segment having a proximal end and extending to a distal end, an inner portion and an outer covering portion, said inner portion comprising a plurality of elongated strands extending from the proximal end and terminating at the distal end and being circularly positioned around a longitudinal axis, each strand including axial twist portions arranged to define a generally helical strand profile, said twist portions complementary with twist portions of adjacent strands along a length of said inner tubular portion for defining said tubular segment thereby without formation of gaps between said strands, said tubular proximal segment having a first length, and a first outer diameter; said tubular distal segment having a proximal end and extending to a distal end, a second length, and a second outer diameter, said first length being greater than said second length, said tubular distal segment comprising a lubricious inner liner and a polymer outer jacket bonded to said lubricious inner liner, said lubricious inner liner extending within said tubular distal segment but not extending into the tubular proximal segment; and a medical interventional device received in said passageway at said tubular distal segment, and deployable from said distal end thereof, said lubricious inner liner providing a slippery, low friction inner surface to thereby ease deployment of said medical interventional device; wherein said medical interventional device comprises an expandable stent, said stent received in said passageway along said tubular distal segment in a compressed condition, and expandable to an expanded condition upon deployment from said distal end.
