Azimuth Sleep Solutions

Azimuth Sleep Solutions was a U.S. medical device startup focused on sleep and respiratory care, particularly products used with CPAP and BiPAP therapy for obstructive sleep apnea. The company developed custom-fit, strapless positive airway pressure mask concepts and also created PortPatch, a filter patch designed to improve filtration on PAP devices. During the COVID-19 pandemic, PortPatch received FDA Emergency Use Authorization as a ventilator accessory intended to help reduce airborne particulate spread in care settings. Available third-party business databases indicate the company was founded in 2019 in the Memphis/Germantown, Tennessee area and later became inactive or out of business. The company appears to have remained a small private venture-backed device company rather than a drug-development biotech.
