Abstract
A catheter including a catheter shaft formed from a polymer blend and/or a braid. The polymer blend may include polyoxymethylene added in the dispersion phase to a polymer blend. The catheter braid can be formed from at least two continuous wires that are woven together. The catheter braid can include a proximal braid section and a distal braid section. Each of the continuous wires has a proximal diameter corresponding to the proximal braid section and a distal diameter corresponding to the distal braid section. The distal diameter of each wire can be less than the proximal diameter of that wire. A catheter braid so formed can be included in a catheter.
