Abstract
The present invention uses sets of strut members where the most distal set of strut members is similar to that of most stents in that the plane of the distal set of strut members is perpendicular to the stent's longitudinal axis. The present invention has a multiplicity of circumferential sets of strut members, but only the distal set of strut members has its plane perpendicular to the stent's longitudinal axis. The more proximal sets of strut members are angulated, so that the plane of the most proximal set of strut members has a preset angle such as 30.degree., 45.degree. or 60.degree. relative to the stent's longitudinal axis. The stent could also be formed from or coated with a highly radiopaque material. Alternately, a radiopaque marker could be placed at the most proximal point of the angulated, side branch stent, for the stent has to be rotated by the clinician until the plane of the most proximal angulated set of strut members is situated to be approximately parallel to the plane of the ostium of the side branch. It is also envisioned to widen the diagonal sections of the most proximal circumferential set of strut members to increase their radiopacity as compared to the radiopacity of the more distal circumferential sets of strut members. This can assist the clinician who places the side branch stent to have it properly placed at the ostium of the side branch.

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.
