Beschreibung
Zusammenfassung:	A medical introducer includes a dilator received in an introducer sheath that includes a composite tube extending between a valve and a tip. The composite tube includes a braid with a hollow cylindrical shape sandwiched between an inner polymer tube and outer thermoplastic tube. The tip includes a loaded thermoplastic radiopaque marker, and a crosslinked polymer sleeve with an outer surface that has a flush transition to an outer surface of the composite tube. The radiopaque marker includes a tapered segment, and the crosslinked polymer sleeve extends distally beyond the polymer tube and serves to reinforce, protect and shape the distal introducer sheath tip.
