No
The summary describes the use of integrated sensors (thermistors and capacitive sensors) to monitor bag filling, drainage, skin condition, and leaks. It mentions data transmission and a companion software suite for displaying this data. There is no mention of AI, ML, or image processing being used for analysis or interpretation of the sensor data. The performance studies focus on the functionality of the sensors themselves.
No.
The device's intended use is to monitor bag filling and drainage, provide cumulative output data, and monitor skin condition, leaks, and stoma visual condition, which are functions related to management and assessment rather than direct treatment or therapy.
Yes
The device monitors several physiological conditions (bag filling, drainage, skin condition, leaks, and visual stoma condition) and provides data to the patient and clinical team, which are functions typical of a diagnostic device.
No
The device description explicitly mentions hardware components like "integrated thermistors and capacitive sensors," a "wafer," and a "Hub" that transmits data. While software is involved (Alfred software suite), the system relies on physical sensors and hardware for its primary function.
Based on the provided information, the SmartBag device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs are used to examine specimens derived from the human body. The SmartBag system monitors the contents of an ostomy bag (urine or feces) and the condition of the skin and stoma externally. It does not analyze biological samples taken from within the body.
- The intended use focuses on monitoring and managing the ostomy bag and surrounding area. The system tracks bag filling, drainage, skin condition, leaks, and stoma appearance. These are all external observations and measurements.
- The device description and performance studies confirm its function is external monitoring. The sensors measure volume and detect leaks within and around the bag and wafer. The bench tests simulate external conditions and outputs.
While the SmartBag system provides valuable information related to a patient's health condition (ostomy output), it does so by monitoring external factors and contents, not by analyzing biological specimens in vitro.

Our reference device (Alfasight 9000TM) suggests that skin thermal regulation and skin temperature can be utilized to identify various organ diseases including abnormalities in female breast, peripheral vascular disease, musculoskeletal disorders, extracranial cerebral and facial vascular disease, abnormalities of the thyroid gland, and various neoplastic conditions. Alfasight 9000TM utilizes thermal sensors and measures the subject's skin surface temperature to indicate deeper level organ diseases, while the SmartBag system has NTC thermistors integrated into the wafer to measure the peristomal skin temperature and indicate peristomal skin complication. In summary, there has been medical evidence of utilizing skin temperature for various diagnosis, supporting our hypothesis that peristomal skin temperature may indicate skin complications.
DEVICE DESCRIPTION
807.92(a)(4)
The SmartBag with integrated thermistors and capacitive sensors can be used in place of a traditional ostomy bag. It notifies patients or medical professionals of any potential leaks around the peristomal skin as well as giving an estimate of the output volume within the bag.

SOFTWARE DESCRIPTION
Alfred software is a companion software suite for SmartBag. It consists of Alfred mobile app and Alfred hospital app. Alfred mobile app is a companion application for mobile phone. The application provides SmartBag user easy access to bag status, hydration tracking and restroom search functionalities. The SmartBag could operate without Alfred mobile app.
The figure below illustrates how data transfer will take place within the SmartBag between the wafer, bag, hub, and 11 Health Cloud. The sensors in the bag and the wafer will be able to transmit data to the hub via NFC protocol communication. The data from the hub will be transmitted to the cloud via LTE-M data transfer via secure MQTT protocol and then this data can be downloaded to web supported devices – such as an iPhone.

Substantial Equivalence Discussion
The primary intended use of an ostomy bag is a collection device. The SmartBag, does not alter an ostomy bag's function as a collection device but rather shares the same attributes with added features. The SmartBag offers a continuous ostomy monitoring system, tracking the estimated volumetric filling of the bag via integrated thermistor and capacitive sensors and potentially indicating the visual condition of the stoma with the optical sensor in the hub. Temperature distribution around the stoma, and anomalies in the temperature can suggest, inter alia, leakage occurrence, developing skin irritation and other phenomena in the peristomal region. Integrated sensors may indicate time of excretion, and data related to output, such as the phase (liquid, solid, semi-solid and gas). Data from the bag and wafer are transmitted securely by NFC to the hub which subsequently transmits data to the cloud via LTE. The data can be downloaded to a hand-held device like a cellphone or tablet for clinical purposes, if clinically indicated. The Smartbag raises no new issues of safety and effectiveness for its intended use but is a technological improvement of current approaches of simple visualization of ostomy fill and is substantially equivalent to both predicate device and reference device identified.
