You have had wire coils inserted into your bronchi.

Air is breathed in via the mouth or nose. From there the air goes to the windpipe via the larynx. At the end of the windpipe are two bronchial tubes (or bronchi) branching away from it. The bronchial tubes run into the lungs. What is more, the bronchial tubes divide into even smaller branches. The larynx, windpipe, bronchia and lungs are part of the lower airways.

You had a bronchoscopy. A bronchoscopy involves inserting an examination instrument via the mouth or nose. Such a device may be a flexible or rigid tube. The device is then pushed down into the lower airways. A camera is attached to the tube. This camera then sends images to a screen during the examination. You can look through the tube.

The bronchoscopy involved inserting some special wire coils into your bronchi. The coils allow less air to get into the bronchi. It makes the relevant parts of the lungs smaller.
