Summary
The USPTO has published a new patent application, US20260083550A1, for a sinus stent system and methods for deployment, assigned to Stryker European Operations Limited. The application details a stent made of flexible foam and film layers designed for deployment within a patient's frontal sinus.
What changed
This document is a publication of a new patent application (US20260083550A1) by the USPTO, detailing a novel sinus stent system and deployment method. The invention, assigned to Stryker European Operations Limited, involves a stent constructed from flexible foam and film layers, designed to maintain patency of the frontal sinus opening. Key features include the potential for an active agent within the foam, bioresorbable foam, and a non-biodegradable film, with specific design elements for ease of removal.
This patent publication does not impose immediate regulatory obligations. However, it signifies a new development in medical device technology for sinus treatment. Companies operating in the medical device sector, particularly those involved in prosthetics or sinus treatments, should be aware of this filing as it may impact future product development, competitive landscapes, and intellectual property strategies. No compliance actions are required based solely on this publication.

Abstract
Systems and methods for deploying a stent within the frontal sinus. The stent includes flexible foam and film layers arranged in a stacked configuration and furled within a cartridge prior to deployment. The cartridge is removably coupled to an applicator device including an actuator. The film layer may include a polymer having a resilience sufficient to unfurl the stent and maintain patency of the frontal sinus opening. The flexible foam layer may have porosity of greater than 80%, and an active agent may be within the flexible foam layer. The flexible foam layer may be bioresorbable and the flexible film layer biocompatible and non-biodegradable. The stent may include first and second body portions with the first body portion independently unfurling from the second body portion to retain the stent within the frontal sinus. Contouring of the first and second body portions may facilitate ease with removal of the stent.
