Pulmonx Corporation
A maker of minimally invasive devices for people with severe emphysema and COPD, Pulmonx built its business around the Zephyr Endobronchial Valve, a tiny one-way implant placed through a bronchoscope to let trapped air escape from diseased lung lobes so healthier tissue can work. The company was founded in California in 1995 by Dr. Rodney Perkins. Its flagship product takes its name from the Greek word for a gentle west wind — a nod to helping patients breathe more easily.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last year: -274.1K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
