Lastovich, and Chad Modra, with application filed October 3, 2024.
What changed
USPTO published patent application US20260096820A1 for an implantable endobronchial valve system designed for lung volume modification. The valve comprises a collapsible and expandable frame with a flexible valve member including nested distal conical and proximal frusto-conical components, along with swellable material to gradually modify fluid flow rates and mitigate pneumothorax complications.
Medical device companies developing or marketing endobronchial valves for COPD or emphysema treatment should monitor this application for potential market implications. If granted, the patent claims could affect freedom-to-operate assessments for similar lung volume reduction devices.
What to do next

Abstract
An endobronchial valve designed for placement in an airway to modify lung volume to a portion of the lung. The valve comprises a frame with a collapsible and expandable configuration, and a valve member made of a flexible material attached to the frame. The valve member includes a distal valve member with a conical shape and nested within a proximal valve member with a frusto-conical shape. The distal valve member features a cavity communicating with an opening at the base, while the proximal valve member has openings of varying diameters. The base of the distal valve member is positioned through the opening of the proximal valve member, allowing for effective modification of lung volume. The valve systems further include a swellable material for changing a fluid flow rate over time to gradually modify lung volume and mitigate complications such as pneumothorax.
