What changed
This document is a published patent application from the USPTO for a "SYSTEM AND APPARATUS TO ASSIST IN PRECISE STENT POSITIONING AT THE OSTIUM OF A BLOOD VESSEL." The application, filed on December 4, 2025, and published on March 26, 2026, describes an apparatus and methods for accurately positioning a stent within the ostium of a blood vessel to ensure the entire circumference of the proximal stent edge is within the aorto-ostial landing zone (AOLZ).
As this is a patent application, it does not impose direct regulatory obligations or compliance deadlines on regulated entities. However, it signifies potential future innovation and intellectual property in the medical device sector, specifically for cardiovascular interventions. Companies involved in the development or manufacturing of stents and related delivery systems should be aware of this filing as it may impact future product development and market competition.

Abstract
Apparatuses and methods for quickly and accurately positioning a stent within the ostium of a blood vessel so that the entire circumference of the proximal stent edge is within the aorto-ostial landing zone (AOLZ). Any of these methods and apparatuses may include an ostial positioning catheter including an annular sealing balloon, a distal reinforced shaft, and a hypotube extending proximally from a longitudinal side of the distal reinforced shaft. These ostial positioning catheters may be independently operated with a guide catheter and a stent deployment catheter.
