Abstract

An intravascular catheter (10,110) having an elongated tubular body with a proximal portion, a distal portion and a lumen extending therebetween. The tubular body is formed with: (a) a first layer (21,128) of polytetrafluoroethylene; (b) a reinforcing element (22,130) at least partially surrounding the inner layer; and (c) a second layer (23,132) comprising a blend of polyetherester elastomer and polybutylene terephthalate at least partially covering the second layer (23,132).
