Endobronchial valves (EBVs) are one-way devices placed endoscopically and are used in the management of emphysema and postoperative air leaks. At present, the endobronchial valve system used at the Golden Jubilee National Hospital is the Emphasys Zephyr® valve (Pulmonx, Inc.), which is MR conditional; up to 3T and first level mode. Example images of the implant are shown below.
