Abstract
This is a delivery catheter assembly used typically, but not exclusively, in the peripheral vasculature of the human body. The catheter is configured in such a way that the lumen is exceptionally large and the catheter wall is exceptionally thin for a catheter of this class. The distal portion of the catheter contains a kink-resisting member, preferably a super-elastic alloy ribbon braid, which is embedded in the catheter wall. Proximally of the kink-resisting member, the catheter typically will have no other kink-resisting members. Finally, the catheter assembly uses long conical joints between component tubular members to provide smooth and strong transitions between those members.
