Claim Text:
1. A flexible kink-resistant introducer sheath comprising: an inner tube extending to a distal end; a wire coil disposed around said inner tube extending to an end spaced proximally from said inner tube distal end, said wire coil comprising a plurality of uniformly spaced coil turns, each coil turn being free from crossing by another coil turn; a first outer tube disposed around said wire coil and said inner tube to a first outer tube distal end spaced proximally from said wire coil distal end such that a distal end portion of said wire coil extends beyond the first outer tube distal end; a radiopaque marker band comprising a first radiopaque material positioned on the introducer sheath at the distal end of the coil and beneath the second outer tube and embedded within an inner surface of the second outer tube; at least a second outer tube disposed around said wire coil and said inner tube therewithin extending distally from said first outer tube distal end and covering said distal end portion of said wire coil and extending beyond said distal end of said inner tube; and an atraumatic flexible, kink-resistant distal tip; said first outer tube being of a material having a first durometer of between 50 D and 60 D, and said second outer tube having a second durometer that is softer than said material of said first outer tube and being between 35 D and 45 D; wherein the second outer tube is polymeric and contains radiopaque filler particles of a second radiopaque material; wherein the first outer tube is polymeric and substantially free of radiopaque filler; and wherein the coil extends only partly within the length of the second outer tube.
