Abstract:
A balloon catheter having an elongate shaft with a proximal section and a relatively short distal section, the distal section comprising:a) a distal inner tubular member comprising a first polymer, and having a longitudinal axis, an outer surface and an inner surface; b) an inflatable balloon disposed about the distal inner tubular member, and having a proximal end, a distal end, and an interior disposed between the proximal and distal end; and c) a tubular flexible radiopaque marker comprising a second polymer located at the distal inner tubular member and disposed within the inflation member interior, having an inner surface and an outer surface that is substantially radially congruent with the outer surface of the distal inner tubular member, such that the longitudinal transition between the outer surface of the marker and the outer surface of the distal inner tubular member is smooth.
