Minnesota Patent of the Month – July 2025
CRYOSA, INC. has been granted U.S. Patent No. 12369965 for its innovative system to treat obstructive sleep apnea (OSA). The patent, titled ‘Systems and methods for treatment of obstructive sleep apnea,’ describes a new method. It uses cryolysis, a process that selectively freezes and removes fat cells. This minimally invasive technology targets fatty tissue in the upper airway. This is a common cause of OSA.
Innovation Overcomes Common Challenges
Existing treatments like CPAP machines are often inconvenient. Surgical options carry risks of bleeding and other complications. This new method aims to fill a critical gap. It focuses on the specific vulnerability of fat tissue to cold. The technology works by applying a chilled liquid or air to the oropharyngeal tissue. This targets the fat cells while sparing surrounding muscle and nerves. The device cools the tissue to a precise temperature for a set time. This causes the fat cells to break down over time.
Designed for Precision and Safety
The patent outlines several applicator designs. They are shaped to fit specific areas. This includes the soft palate and the base of the tongue. One design even includes a safety insulator. It protects non-target tissue. This controlled approach promises a safer, more effective solution. The invention offers a permanent alternative to current, less-than-ideal treatments.

What is the R&D Tax Credit?
The Research & Experimentation Tax Credit (or R&D Tax Credit), is a general business tax credit under Internal Revenue Code section 41 for companies that incur research and development (R&D) costs in the United States. The credits are a tax incentive for performing qualified research in the United States, resulting in a credit to a tax return. For the first three years of R&D claims, 6% of the total qualified research expenses (QRE) form the gross credit. In the 4th year of claims and beyond, a base amount is calculated, and an adjusted expense line is multiplied times 14%. Click here to learn more.
