Intended Use

The Omnipod DASH Insulin Management System (the Pump) with interoperable technology is intended for subcutaneous delivery of insulin at set and variable rates for the management of diabetes mellitus in persons requiring insulin.

The Pump is able to reliably and securely compatible, digitally connected devices, including automated insulin dosing software, to receive, execute and confirm commands from these devices.

The Pump is intended for single patient, home use and requires a prescription. The Pump is indicated for use with NovoLog, Humalog, Admelog, or Apidra U-100 insulin.

Device Description

The Omnipod DASH™ Insulin Management System with interoperable technology provides for the management of insulin therapy by patients with diabetes mellitus. It is comprised of two primary components: the disposable insulin infusion pump (Pod), and an associated Bluetooth Low Energy (BLE) enabled remote controller. The Omnipod DASH System with interoperable technology is provided with the DASH Personal Diabetes Manager (PDM), but future alternate controllers may be established. The DASH PDM incorporates a suggested bolus calculator which aids the user in determining the insulin bolus dosage needed based on carbohydrates ingested, most recent blood glucose reading, programmable correction factor, insulin to carbohydrate ratio, target blood glucose value and Insulin on Board (IoB).

The Pod is a body-wearable insulin pump that affixes to the user on the back of the arm, the lower back or abdomen, the thigh area, or any site that has a layer of fatty tissue available. It is held in place by an adhesive pad and provides up to three days of insulin before it is removed and replaced with a new Pod. The DASH PDM is a handheld device that controls the Pod. The user interfaces with the device system through the DASH PDM using a touch screen, similar to a smartphone, where they control basal and bolus delivery and various insulin program settings and calculations. The DASH PDM also has a food library to assist with carbohydrate calculations, and it maintains several variables in a history log for the viewer to track their diabetes therapy. The device system is for prescription use only.

The remote control design of the Pod inherently enables connectivity to other interoperable controllers with new functionality. Capabilities can be built into compatible controllers to add functionality such as Automated Insulin Delivery (AID) systems. In this design, a controller may contain an algorithm and connect to an iCGM system. In such an integrated system, the AID controller would be responsible for coordinating the interoperable devices (Omnipod DASH and iCGM) in order to automate delivery. It would read the Pod for insulin delivery status, read the iCGM for the sensor value, compute an automated delivery amount and then command the Pod to deliver the required insulin amount. For this automated delivery to occur, the Controller is required to be in range of the Pod. The Pod is designed to the programmed basal rate in the case of extended loss of communication.

AI/ML Overview

This document describes the Omnipod DASH™ Insulin Management System with interoperable technology. It is a 510(k) premarket notification for a Class II medical device, an alternate controller enabled infusion pump.

Key takeaway: This documentation confirms that the Omnipod DASH system is a medical device for insulin delivery, and the submission is for expanding its indications for use to include interoperable technology, allowing it to communicate with compatible digital devices. The FDA has determined it is substantially equivalent to existing devices.

Here's an analysis based on the provided text, focusing on the requested criteria for an AI/ML device, even though this document is for an infusion pump. It's important to note that the provided text is for an insulin pump, not an AI/ML diagnostic or assistive device. Therefore, many of the requested criteria (like ground truth, MRMC studies, expert adjudication) are not applicable in their typical sense for this type of medical device.

However, I will interpret the acceptance criteria in the context of a medical device submission, particularly for an infusion pump, and extract information where parallels can be drawn.


Acceptance Criteria for Omnipod DASH™ Insulin Management System with Interoperable Technology

The acceptance criteria for this device, as outlined in the "Special Control" section, predominantly focus on the safety and performance of the insulin pump itself, especially given its new interoperable functionality. The performance data presented demonstrates how the device meets these controls, often by stating that the subject device is identical to previous cleared versions (K182630 and K180045) and that previous testing is applicable, with some additional characterization.

1. Table of Acceptance Criteria and Reported Device Performance

Acceptance Criteria Category (Special Control)Reported Device Performance and Evidence Provided
Infusion Delivery Accuracy: Device infusion delivery accuracy conforms to defined user needs and intended uses and is validated to support safe use under actual use conditions (includes specifications for ambient temp, pressure, fluid properties; testing met design input requirements for programmable range of rates/volumes, statistically valid number of devices).All performance testing from K182630 and K180045 is applicable. Further characterization conducted and submitted in this 510(k). Delivery accuracy was specifically conducted for this submission (though specific results are not detailed in this summary).

The performance testing provided in K182630 and K180045 are applicable to the subject device.

2. Sample Size Used for the Test Set and Data Provenance

The document does not explicitly state the specific sample sizes for tests. It generally refers to previous clearances (K182630, K180045) for most testing, stating that the subject device is "identical" or that previous testing is "applicable," with "further characterization" or "delivery accuracy" specifically conducted for this submission.

  • Sample Size: Not explicitly stated for specific tests in this summary. It mentions "statistically valid number of devices" as a requirement for delivery accuracy testing in the special control.
  • Data Provenance: The data comes from the manufacturer's (Insulet Corporation) internal testing and previous FDA submissions (K182630, K180045). The country of origin for the data is not specified but is implied to be within Insulet's testing facilities (Acton, MA, USA is their address). The data would be prospective in nature, generated specifically for these regulatory submissions.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of Experts

This information is not applicable in the context of this device. The Omnipod DASH Insulin Management System is an infusion pump, not a diagnostic device that relies on human expert interpretation of data (like medical images) to establish ground truth. The "ground truth" for this device relates to its physical and functional performance (e.g., accurate insulin delivery, proper communication), which is established through engineering and performance testing against predefined specifications.

4. Adjudication Method for the Test Set

This information is not applicable. Adjudication methods like 2+1 or 3+1 are used in studies where human readers are interpreting data or making diagnoses, and their initial assessments need to be reconciled to establish a consensus ground truth. For an infusion pump, performance is measured objectively via test equipment and quantitative outputs.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done

No, an MRMC study was not done or applicable. MRMC studies compare the performance of human readers, sometimes with and without AI assistance, especially in diagnostic imaging or similar fields. This device is an insulin pump, not a diagnostic tool where human interpretation is being augmented.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was Done

This concept is partially applicable but in a different context. The "algorithm" here is the pump's internal software controlling insulin delivery and communication. The "standalone" performance would be the pump's ability to deliver insulin accurately and communicate reliably based on pre-programmed settings or commands, independent of a human directly monitoring every millisecond. The performance tests (delivery accuracy, hazard detection, interoperability) are essentially evaluations of the pump's "standalone" (or automated) functional performance. The human (user) interacts with the PDM to initiate commands, but the core function (insulin delivery) is automated by the pump's internal algorithms.

7. The Type of Ground Truth Used

The "ground truth" for this device's performance is based on engineering specifications, established physical measurement methods, and regulatory standards for insulin pump function and safety.

Examples:

  • For "infusion delivery accuracy," the ground truth is the precisely measured volume of fluid delivered compared to the commanded volume, determined using calibrated equipment.
  • For "hazard detection," the ground truth is a simulated hazard (e.g., occlusion) and the objective measurement of the time taken for the pump to detect and alarm, compared against predefined safety limits.
  • For "biocompatibility," the ground truth is the absence of adverse biological reactions, confirmed by standardized in-vitro and in-vivo tests according to ISO standards.

8. The Sample Size for the Training Set

This is not applicable in the AI/ML sense. This device is a traditional medical device (an infusion pump) with embedded software. It does not learn or get "trained" from data in the way a machine learning algorithm does. Its operation is based on deterministic algorithms and hardware.

9. How the Ground Truth for the Training Set Was Established

This is not applicable as there is no "training set" for an AI/ML model for this device. The ground truth for its development and validation (e.g., engineering specifications, performance requirements) is established through established medical device development processes, risk analysis, and compliance with national and international standards (e.g., ISO, FDA guidance).
