The assembly includes a delivery catheter having a deployment lumen with a distal end arranged to receive the intra-bronchial device in a delivery configuration, and arranged to be passed down a trachea and advanced to a location for deployment of the intra-bronchial device, and to deploy the intra-bronchial device by retracting the deployment catheter. The assembly further includes a bronchial device supply tool associated with the distal end, and arranged to carry the intra-bronchial device in a storage configuration and to load the intra-bronchial device in a delivery configuration into the deployment lumen of distal end, and the intra-bronchial device carried in the supply tool in a storage configuration. An embodiment of the supply tool includes a storage portion, a delivery portion, and a configuration-changing portion coupled between the storage portion and the delivery portion.
