A reduced diameter stent/graft deployment catheter and a method of insertion for said catheter. The delivery sheath portion of the catheter, i.e. the distal portion of the catheter containing the stent/graft, has a larger outer diameter than the remaining proximal portion of the catheter. The reduced outer diameter of the body of the catheter allows for the use of a smaller diameter introducer sheath. The method of inserting said catheter comprises the following steps: First, the delivery sheath portion of the catheter is inserted into the patient. Next, an introducer sheath, with an outer diameter which is no larger than the outer diameter of the delivery sheath, is disposed about the catheter and its distal portion inserted into the patient. The catheter is then advanced into the patient and the stent/graft deployed.
