Abstract
A method of endoluminally bypassing blood flow through an aneurysm in the vicinity of a branched blood vessel is provided. The method comprises the steps of advancing a graftstent complex through each branch of the branched blood vessel, aligning the cephalic stents of each of the graftstent complexes relative to each other in a common vessel above the aneurysm, and deploying each of the aligned cephalic stents in the common vessel. The invention also provides an expanded vascular stent having a non-circular cross-section and an apparatus for expanding the stent in this manner. Preferably, the expanded stent is generally 'D' shaped for collateral deployment within a common body lumen. A curved edge of the stent engages a body lumen while an alignment edge engages a collaterally deployed stent. A segment of graft material having at least one end cut on a bias may be attached to the stent so that the graft material extends substantially between the proximal and distal ends of the stent along its alignment edge, yet only partially along its curved edge to assist in forming a hemostatic seal. The apparatus may also be used for collaterally deploying stents within the common body lumen. The invention further provides an apparatus for rotationally aligning the stent alignment edges by providing an indication of the relative rotational alignment of the indwelling stents on a portion of the apparatus which remains external to the patient.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
