ABSTRACT:
Catheters having a pre-shaped tip configuration are disclosed. A catheter in accordance with an illustrative embodiment of the present invention can include an elongated tubular shaft equipped with a distal tip section having a pre-shaped tip configuration that can be used to facilitate tracking of the device through particular locations of the vasculature. The catheter may include a number of features that transition the stiffness and flexibility characteristics of the device and provide a means to radiographically visualize the catheter within the body.
