Delivery catheter that controls foreshortening of ribbon-type prostheses and methods of making and use

摘要

The present invention is directed to a delivery catheter for use in deploying a vascular prosthesis having a self-expanding helical section for use in a wide range of interventional applications. The delivery catheter comprises an elongated member having a helical ledge with a pitch selected to impose a predetermined amount of foreshortening on the vascular prosthesis during deployment. Methods of making and using the delivery catheter of the present invention also are provided.
