Inspire Medical Systems, Inc.
A medical-devices company making a mask-free alternative to CPAP machines for people with obstructive sleep apnea. Its device, sometimes nicknamed a "tongue pacemaker," is surgically implanted under the skin of the chest; during sleep it senses each breath and sends a mild pulse to a nerve that moves the tongue forward, keeping the airway open. The company was founded in 2007 as a spin-off from Medtronic, and it takes its name from the way the system acts on each breath's inspiration.

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 all recorded history: -7.17M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
