Intended Use

The AbStats Gateway is a compact device with integrated sensor interfaces and embedded computing system (stethoscope) that in conjunction with external sensors constitutes the AbStats system. The Ab-Stats system external sensors are placed on the abdomen and identify the vibratory signals associated with digestive processes. This device should be used under the direction of a licensed healthcare when it is required to determine this patient digestive state. The device has not been tested for and it is not intended for pediatric use.

Device Story

AbStats Gateway is a compact, tablet-sized electronic stethoscope system used by healthcare practitioners to monitor intestinal motility. It utilizes two external sensors placed on the patient's abdomen to detect vibratory acoustic signals associated with digestive processes. The system includes a usage assurance feature: a small vibration source in each sensor emits a 50ms, <1 kHz signal every 2 minutes to confirm proper sensor-to-skin contact. The device processes these acoustic inputs to calculate a 'Motility Rate' based on the arrival of detected events. Output is displayed to the clinician to assist in assessing the patient's digestive state. The system uses disposable, FDA-approved adhesive dressings for patient contact, eliminating the need for cleaning. It is designed for clinical environments to provide objective data on gastrointestinal function.

Clinical Evidence

No new clinical trials were conducted for this submission. Evidence relies on a previously published clinical study: 'Validation of an acoustic gastrointestinal surveillance biosensor for postoperative ileus' (J Gastrointest Surg 2014), which served as proof-of-function. Bench testing (TR-001) confirmed system operation, including sensor detection, recording cycles, and usage assurance functionality.

Technological Characteristics

Compact, tablet-sized electronic stethoscope; 5V USB power; two 30mm x 20mm electret microphone sensors; 2.0m flexible cables. Patient contact via 3M Tegaderm adhesive. Complies with IEC60601-1:2005 (safety) and EN60601-1-2:2007 (EMC). Software is moderate level of concern.

Indications for Use

Indicated for adult patients requiring determination of digestive state via abdominal vibratory signal monitoring. Not intended for pediatric use.

## Device Description:

The AbStats Gateway is a compact device with integrated sensor interfaces and embedded computing system (stethoscope) that in conjunction with external sensors constitutes the AbStats system. The Ab-Stats system external sensors are placed on the abdomen and identify the vibratory signals associated with digestive processes.

The AbStats Gateway system is a compact, rapidly deployable unit that is comfortable for subjects and convenient in application. The AbStats Gateway sensor includes a standard microelectronic microphone for measurement of vibration acoustic signals. The components in patient contact are disposable, avoiding the need for cleaning and disinfection. The only material in direct contact with the subject is standard, FDA-approved 3M Tegaderm wound bandage adhesive material.

The AbStats Gateway sensor includes a system that provides usage assurance of proper application to the patient. The AbStats Gateway sensor includes both an electret microphone and a compact vibration source (based on the principle of standard signaling vibration sources in consumer pager and

smartphone systems). This small electronic vibration device emits a short duration (50 millisecond length) signal each 2 minutes during usage and alternately from each sensor.

This low amplitude and low frequency (less than 1 kHz) vibration signal is not detectable by the subject. lt propagates between the two AbStats sensors where it is detected by the AbStats device and provides direct assurance of proper application of the two sensors.

The AbStats Gateway sensor includes fine, flexible cables that connect to the AbStats Gateway. The AbStats Gateway is a low voltage device that is similar in size to a tablet computer. The AbStats Gateway monitors the AbStats sensor signals and provides a measurement of intestinal motility with a Motility Rate. The rate is calculated based on rate of arrival of acoustic events detected by AbStats sensors.

### Conclusions:

Since the comparison of bench testing to clinical outcomes is still not well understood for this type of device, clinical testing was required to support substantial equivalence in the form of functional evaluation and proof of function. The non-clinical data support the safety and effectiveness of the device and the hardware and software verification and validation demonstrate that the AbStats Gateway device should perform as intended in the specified use conditions. The clinical data demonstrate that the AbStats Gateway device functions in a manner comparable to the predicate device that is currently marketed for the same intended use.

The AbStats Gateway device utilizes the same technologies as the predicate device and is considered to be substantially equivalent to the predicate device in form, fit, function, safety and efficacy.
