Overview

Gastric Alimetry is a pioneering, non-invasive medical device and system developed by Alimetry for Body Surface Gastric Mapping (BSGM), designed to aid in the diagnosis of various gastric disorders. It addresses the challenge of diagnosing chronic gastric symptoms like nausea, bloating, and pain after eating, where traditional methods often fall short.

The system comprises a single-use adhesive patch (Gastric Alimetry™ Array) with 66 electrodes, an Alimetry™ Reader to acquire and digitize data, and a Gastric Alimetry™ App for device setup, patient symptom tracking, and data transfers. Patients wear the device in a clinical setting, logging symptoms via the app during a 30-minute pre-meal baseline recording and a 4-hour post-meal recording after consuming a standardized meal.

The collected gastric electrophysiology data is sent to the Alimetry™ Cloud, where advanced AI-driven algorithms process and analyze the faint gastric signals, which are 100 times weaker than cardiac signals. This high-resolution approach allows for the measurement of the stomach’s electrical rhythms, similar to an ECG for the heart. The system also integrates mental health profiling through gut-brain health questionnaires in the app, providing a comprehensive view of symptoms and potential comorbidities.

An auto-generated Gastric Alimetry™ Report is delivered to clinicians via the secure, HIPAA and GDPR compliant Alimetry™ Cloud, offering objective, data-driven insights to inform diagnosis and personalize treatment. This technology aims to reduce the cost, time, and complexity of gut health diagnostics, moving from trial-and-error to clarity of care.

What Physicians Need to Know

AI-Powered Gastric Motility Analysis
Gastric Alimetry utilizes AI-driven algorithms to process faint gastric electrical signals captured by a wearable patch. This advanced analysis provides high-resolution insights into gastric function and motility, aiding in the diagnosis of various gastric disorders.
Procedure Documentation
The system generates an auto-generated Gastric Alimetry Report, delivered via a secure cloud portal, which provides clinicians with objective, data-driven insights on gastric electrophysiology and patient-reported symptoms to inform diagnosis and personalized treatment.
Quality Metrics Tracking
Gastric Alimetry aids in tracking quality metrics by providing objective data to determine if gastric function is normal or abnormal using validated normative values. It also integrates patient symptom logging and gut-brain wellbeing surveys, offering a comprehensive view to guide treatment pathways and enhance clinical care.
Physician Tip

Gastric Alimetry offers a non-invasive, high-resolution method to assess gastric neuromuscular function and correlate it with patient-reported symptoms, providing clarity for chronic unexplained gastric issues. This can significantly reduce diagnostic uncertainty and enable more targeted, personalized treatment plans, moving beyond traditional trial-and-error approaches. Consider its utility for patients with symptoms like chronic nausea, bloating, or pain where conventional tests have been inconclusive. The integrated symptom profiling, including gut-brain axis considerations, offers a holistic view of the patient's condition.

Gastric Alimetry operates as a standalone diagnostic system, utilizing a wearable device and a cloud-based platform for AI-powered data analysis and report generation. While it does not directly integrate with endoscopy systems, the objective insights it provides can inform decisions regarding subsequent endoscopic procedures or other interventions. The Alimetry Cloud ensures secure, HIPAA and GDPR compliant access to patient reports.

What the Web Says

Gastric Alimetry is a non-invasive medical device that uses body surface gastric mapping (BSGM) to assess stomach function and aid in diagnosing gastroduodenal disorders. It's designed to provide objective, data-driven insights into gastric motility, sensitivity, and neuromuscular function, which can help clinicians create more personalized treatment plans. The system combines a wearable electrode patch with a symptom-logging app, and its AI-powered analysis aims to overcome the limitations of traditional, often inconclusive, diagnostic methods like gastric emptying scintigraphy (GES).

Overall: Positive

Strengths

  • Non-invasive, avoiding tubes, scopes, or sedation required by traditional tests.
  • Provides objective, data-driven insights into gastric function and motility.
  • Aids in more accurate diagnosis and personalized treatment plans for complex gastric disorders.
  • Can differentiate between gastric muscle/nerve issues and brain-gut dysfunction.
  • Higher diagnostic yield compared to gastric emptying scintigraphy (GES).
  • Reduces the need for multiple investigations and can lower healthcare utilization costs.

Limitations

  • The test requires a significant time commitment (around 10.5 hours total, including a 4-hour post-meal recording).
  • Patients are advised to limit movement, talking, and laughing during the test, which can be challenging.
  • The test meal (e.g., an Ensure drink and a protein bar) may be difficult for some patients to tolerate, potentially provoking symptoms.
  • Some patients may experience mild skin redness, itch, or rash from the adhesive patch.
  • The test is currently validated for a BMI of up to 35, and results for BMI > 35 should be interpreted with caution.
  • Does not evaluate all features of gastric function, such as gastric accommodation, pyloric function, or transit times.

Frequently Asked Questions

Gastric Alimetry utilizes AI-driven algorithms in the cloud to process faint gastric electrical signals detected by a wearable array, providing objective and data-driven insights into gastric function. This advanced analysis, trained on thousands of diverse test cases, offers more precise identification of motility patterns and aids in diagnosing conditions like gastroparesis and functional dyspepsia, which traditional methods often find challenging.
Gastric Alimetry has received multiple FDA 510(k) clearances in the U.S., CE Mark in Europe, and approvals in New Zealand and the UK. The system ensures patient data privacy and compliance by adhering to stringent regulations such as HIPAA and GDPR for its cloud-based AI platform.
Gastric Alimetry offers a non-invasive, high-resolution assessment of gastric electrical activity, providing functional insights beyond anatomical imaging. It aims to overcome the limitations of traditional electrogastrography (EGG) by offering greater specificity and symptom correlation, and provides more detailed information on neuromuscular pathologies than gastric emptying scintigraphy. It is particularly valuable when existing tests are inconclusive, invasive, or involve radiation, offering a clearer diagnostic pathway.
Gastric Alimetry has secured a dedicated CPT III reimbursement code (0868T), effective July 1, 2024, in the U.S., which facilitates data collection and paves the way for broader reimbursement. CPT III codes are temporary and carrier-priced, meaning individual payers will review and determine payment based on submitted claims. The cost structure typically involves a single-use array for each patient, with other system components being reusable.
While highly effective in narrowing down potential causes of gastric discomfort, Gastric Alimetry's AI may not track every individual gut issue, and some patients might still require additional testing for a definitive diagnosis. The system's algorithms are continuously being enhanced, but like all diagnostic tools, their applicability and accuracy can vary in rare atypical patterns or very early-stage diseases.
Gastric Alimetry reports are automatically delivered to the Alimetry Cloud, a secure portal accessible by clinicians from any connected device using a personal login. While specific EMR integration methods are not detailed, the cloud-based nature suggests standard interoperability options, and the system uses an iPad mini for device setup, patient symptom tracking, and data transfers.
Alimetry provides resources and support, including an interpretation guide, to assist clinicians in understanding and utilizing the Gastric Alimetry reports. This support aims to ensure effective interpretation of the objective, data-driven insights provided by the AI, aiding in informed clinical decisions and personalized treatment pathways.
