Abstract
A delivery catheter and method for positioning an intraluminal graft within a branching vessel in a patient's body and a delivery catheter for use in that method is described. The delivery catheter comprises an elongate catheter having preferably an inflatable balloon adjacent one end, an intraluminal graft disposed about the balloon that bifurcates into two short tubular extensions, and a thin supplementary catheter containing a guidewire that extends upstream through one of the first tubular extensions and downstream through the other of the short tubular extensions of the graft. The method for positioning the intraluminal graft using the delivery catheter is particularly applicable to the appropriate positioning of a trouser graft so that it bridges an aneurysm which extends from a single vessel, such as the aorta, into one or more divergent vessels, for example, an iliac artery.
