The study objective is to demonstrate the equivalence of the Atmo Motility Gas Capsule System with the predicate SmartPill in measuring gastric emptying time and colonic transit time through examination of device agreement.
The clinical protocol for the study is designed to compare the performance of the Atmo Motility Gas Capsule System to the predicate device, the SmartPill GI Monitoring System, in patients with chronic GI symptoms suggestive of GI motility disorders (specifically gastroparesis and slow transit constipation), in order to demonstrate substantial equivalence. This study will involve the recruitment of symptomatic participants from a population that is representative of that for which the device is intended. The primary objective of this study is the assessment of the agreement of Atmo Motility and SmartPill Systems' results with regards to both GET and CTT. The SmartPill is the accepted gold standard test for GI motility transit time analysis. Device agreement will be primarily examined through Bland-Altman analyses for GET and CTT measurements from the Atmo Motility and SmartPill Systems.

The Atmo System measures whole gut and regional gut transit times. Measurements of GI tract transit times are used for evaluating motility disorders. Gastric emptying time (GET) is indicated for the evaluation of patients with suspected gastroparesis. Delayed GET is implicated in such disorders as idiopathic and diabetic gastroparesis and functional non-ulcer dyspepsia. Colonic transit time (CTT) is indicated for the evaluation of colonic transit in patients with chronic constipation, to aid in differentiating slow and normal transit constipation. In the case where ileocecal junction transit cannot be determined the system will report combined Small and Large Bowel Transit Time (SLBTT). Transit times are derived from measures of temperature, relative humidity, hydrogen concentration, and carbon dioxide concentration, in conjunction with indicators of fermentation activity, capsule tumble, and antenna reflectance. Not for use in pediatric patients.
The SmartPill GI Monitoring System (Medtronic) offers a method for measuring gastric emptying time (GET), small bowel transit time (SBTT), colonic transit time (CTT), small bowel large bowel transit time (SLBTT) and whole gut transit time (WGTT) with a single test, which can be used as an aid for the diagnosis of both gastroparesis and slow transit constipation. The SmartPill System measures pH, temperature and pressure. It is approved for use in the measurement of GI transit times by the FDA.
