What changed

This document is a publication of a United States patent application (US20260083544A1) filed by inventors Adam J. Shipley, Torey Hovest, and others, on September 15, 2023. The application describes a novel stent graft design featuring a low-profile passive sealing skirt that lies flat on the stent in a delivery configuration and radially protrudes outward during deployment to improve sealing with surrounding structures, such as blood vessels. The patent application includes specific CPC classifications related to prosthetic devices.

As this is a patent application, it does not impose direct regulatory obligations or compliance deadlines on manufacturers. However, it represents a new development in medical device technology that may impact future product development, intellectual property strategies, and market competition within the medical device sector. Companies involved in the design, manufacturing, or sale of stent grafts should be aware of this filing for competitive intelligence and potential patent landscape analysis.

Abstract

The techniques of this disclosure generally relate to a method including providing a sealing stent graft. The sealing stent graft includes a graft material, a stent coupled to the graft material, a sealing skirt of the graft material lying flat on the stent, and a collapsing suture coupled to the graft material. The method further includes expanding the stent to cause the collapsing suture to collapse the sealing skirt. Accordingly, the sealing skirt lies flat and does not impact the packing density of sealing stent graft when in a delivery configuration. During deployment, the collapse of the sealing skirt causes the sealing skirt to protrude radially outward. This thickening of the sealing skirt improves sealing of the sealing stent graft with other structures, e.g., vessels.
