Abstract:
A catheter assembly comprising an elongate tubular member having a proximal end, a distal end, an axis, and a passageway defining an inner lumen extending between those ends, comprisinga.) a relatively less flexible and proximal segment, comprisingi.) a proximal braid member having a proximal end and a distal end, woven of a plurality of proximal braid elements, and having inner and outer surfaces,ii.) at least one lining member comprising a polymer located interior to said more proximal braid member, andiii.) at least one covering member comprising a polymer located exterior to said proximal braid member, andb.) a relatively more flexible distal tubular segment comprising:i.) a distal braid member, having a proximal end and a distal end, woven of a plurality of distal braid elements, said distal braid elements being less than in number than said proximal braid elements, and having inner and outer surfaces,ii.) at least one lining member comprising a polymer located interior to said distal braid member, andiii.) at least one covering member comprising a polymer located exterior to said distal braid member.
