Hi @danaj60, welcome to Mayo Clinic Connect. You'll notice that I replaced the copied article with a link to the In The Loop blog. I also moved your post to this existing discussion so that you connect with members like @djallan @carolannz and @fracuredd who live with obstructive pulmonary disease (COPD) and may have had endoscopic lung volume reduction, sometimes also referred to as Zephr valve (one manufacturer).

This procedure, which recently was approved by the Food and Drug Administration (FDA), treats patients experiencing disorders associated with chronic COPD, including advanced emphysema and chronic bronchitis. Only a few medical centers nationwide offer this treatment.

Dana, is your father a candidate for this procedure? Is he already a patient at Mayo Clinic?
