The document describes an "Algorithm" for analyzing heart sounds and identifying murmurs, but it does not explicitly state whether this algorithm utilizes AI or ML techniques. The lack of mention of AI, ML, DNN, training sets, or test sets makes it impossible to definitively confirm the presence of AI/ML.
No
This device is designed to acquire, record, and analyze heart sounds to support diagnosis, not to treat a condition. While it aids in the evaluation of patients' heart sounds for diagnostic purposes, it does not provide therapy.
Yes
The device description explicitly states, "The SensiCardiac Mobi Diagnostic Heart Murmur Application is a decision support device intended to acquire, record, and anlyze heart sounds. It is used to distinguish between normal/ physiological and pathological heart murmurs..." and its intended use is to "provide support to the physician in the evaluation of patients' heart sounds," identifying "specific heart sounds that may be present. Identified sounds include S1, S2, and suspected murmurs." These functions align with the definition of a diagnostic device, even though it's not intended as a sole means of diagnosis and requires physician over-read.
No
The device description explicitly states that the complete system includes a hand-held device (iPhone 4S or later) and a compatible electronic stethoscope, in addition to the software algorithm. While the software is a key component, the system relies on specific hardware for data acquisition and display.
Based on the provided information, the SensiCardiac Mobi is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information about a person's health. This testing is performed outside of the body.
- SensiCardiac Mobi Function: The SensiCardiac Mobi acquires and analyzes acoustic signals from the heart within the patient's body using an electronic stethoscope. It does not analyze biological specimens.
The device is a diagnostic support tool that analyzes physiological signals acquired directly from the patient. This falls under the category of medical devices that interact with the body or analyze signals from the body, rather than IVDs.

COMPARISON OF TECHNICAL CHARACTERISTICS
807.92(a)(6)
The SensiCardiac Mobi software device features were directly compared with the FDA cleared Sensi Cardiac Diagnostic Heart Murmur Software. Both systems use the exact same Diagnostic Heart Murmur Algorithm and electronic stethoscope to capture the heart sounds. The user interface was adapted to function on the latest mobile hand held devices and the algorithm implemented as a hosted service.
Synopsis of the comparison analysis:
- . Both systems use the exact same (identical) Diagnostic Heart Murmur Algorithm for analyzing the heart sounds. No modifications were made to the FDA cleared Sensi Cardiac Diagnostic Heart Murmur Software's algorithm and used as is within SensiCardiac Mobi.
- . Both systems use equivalent computer platforms to execute the Diagnostic Heart Murmur Algorithm. No computational or control functions were implemented on the mobile hand held device.
- . Both systems interfaces to the same electronic stethoscope (ThinkLabs Medical ds32a+).
- . Equivalent patient information is captured on both platforms.
- The clinical performance of both systems is equivalent. .
- · An equivalent workflow and graphical user interface were implemented on SensiCardiac Mobi, as used within the FDA cleared
- . The new SensiCardiac Mobi software's graphical user interface is nearly identical to the previous FDA cleared Sensi Cardiac Diagnostic Heart Murmur Software.
After analyzing bench test and user testing data, it is the conclusion of Diacoustic Medical that the SensiCardiac Mobi device consisting of the Sensi Diagnostic Heart Murmur Software and compatible electronic stethoscopes is as safe and effective as the predicate device and raises no new issues of safety and effectiveness.
SAFETY AND EFFECTIVENESS
807.92(b)
A comprehensive list of verification and validation testing was performed in accordance to Diacoustic's Design Control procedures.
Software validation was performed for all aspects of the SensiCardiac Mobi system and software. The graphical user interface and usability were compared to the predicate devices.
Validation of the SensiCardiac Mobi was performed to ensure that the SensiCardiac Mobi system consistently fulfills its intended use and the needs of the user. Software validation was performed to insure the performance of the software algorithm is identical to that of the Sensi Cardiac Diagnostic Heart Murmur Software.
