Abstract: An intravascular delivery catheter includes a middle member or manipulator to ameliorate the effect of buckling of the graft cover during the tracking or positioning of the delivery device within a body flow lumen to deploy an exclusion device, such a stent graft. The delivery device/catheter includes a region or regions of lower resistance to bending than other portions of the delivery device, which are positioned, within the delivery device, to preferentially bend the delivery system at locations where buckling will have minimal effect upon the deployment of the exclusion device from the delivery system.

Abstract: An apparatus and method of use is disclosed for an integrated detachable introducer with a catheter assembly. The integrated detachable introducer is used to seal an incision to the blood vessel once the catheter delivery system has delivered the proper therapy or therapeutic device. If additional therapy is required, the blood vessel may be accessed through the integrated detachable introducer. An integrated detachable introducer is disclosed for use with a catheter assembly. The catheter assembly includes a shaft, a handle and an implantable therapeutic device mounted on the shaft. The integrated detachable introducer includes an introducer body designed to releaseably couple with the handle, and an introducer sheath that is coupled the introducer body. The integrated detachable introducer further includes a lumen extending through the introducer body and the introducer sheath; the lumen is sized to slideably fit over the shaft of the catheter delivery system.
