  • Publication number: 20070049899
    Abstract: An improved apparatus and method to catheterize passages is disclosed. The present invention provides a catheter having a soft flexible pre-formed distal tip, that when used in combination with commercially available guidewires of variable stiffness, results in the ability to control the direction and angle of wire advancement allowing cannulation of body passages, including those that arise at acute angles. The catheter can have a longitudinal axis, a proximal section and a distal section having a soft flexible pre-formed tip having a curvature of ninety degrees or greater and shape retention. The catheter can have an inner wall that defines a lumen that runs along said longitudinal axis forming a single continuous tube, a reinforcement braid disposed over the inner wall, and an outside covering disposed over the reinforcement braid. A spacer can be added between said wall liner and said reinforcement braid in the proximal end.
