Atmo Biosciences is delighted to announce that we have just received US Food and Drug Administration (FDA) 510(k) clearance for a new Contractility Frequency Map feature as an enhancement to the existing Atmo Gas Capsule System.

This clinically valuable feature is a visualisation of capsule movement caused by gastrointestinal pressures and contractions throughout the regions of the GI tract. It enables clinicians to see the different rates and intensities of contractile activity in the stomach, small bowel, and colon.

The data provides insights into physiology and helps confirm the device’s location at a given time, complementing existing data outputs from the Atmo Capsule that identify transitions from one region of the gastrointestinal tract to another. The outputs are delivered in a visual format making it easier to interpret and provides additional information to improve the clinician’s confidence in the diagnosis of highly prevalent dysmotility conditions such as gastroparesis and slow transit constipation.

The Atmo Gas Capsule System delivers the information in one convenient test without exposure to radiation, and allows the patient to go about their daily activities for the duration.

“The ability to measure contractility directly, together with simultaneous measurements of transit times, will position the Atmo Capsule as a valuable tool for providing comprehensive, objective assessments of gut physiology.” Noted by Dr. William L. Hasler, Mayo Clinic

The new Contractility feature was the subject of two posters, both of which won “Poster of Distinction” awards at the Digestive Disease Week (DDW) conference in Chicago recently, which is the world’s largest gathering of Gastroenterology experts. A Journal article on the utility of the contractility feature has also been published in Neurogastroenterology & Motility (Hasler et al. 2026).

Mal Hebblewhite, President and CEO of Atmo Biosciences comments “The addition of the Contractility Frequency Map is an example of Atmo’s commitment to address unmet clinical needs through R&D and innovation. By capturing gastrointestinal contractions and pressures derived from the capsule’s movement, we are providing clinicians with complementary data that enhances patient care.”

The Contractility Frequency Map is now included as a standard feature in the existing FDA-cleared Atmo Gas Capsule System. The feature will deploy to existing customers automatically on June 8th by virtue of Atmo’s cloud-connected system.
