The document describes a transcutaneous electrical nerve stimulator controlled by a microprocessor and an app, but there is no mention of AI or ML algorithms being used for treatment parameters, analysis, or any other function. The control is based on user input and pre-programmed modes.
Yes
The "Intended Use / Indications for Use" section explicitly states that the device is "intended to be used in adult patients with functional abdominal pain associated with irritable bowel syndrome (IBS) through application... as an aid in the reduction of pain when combined with other therapies for IBS," indicating its purpose is to treat or alleviate a medical condition.
No
The device is described as a 'transcutaneous electrical nerve field stimulator system' intended to aid in the 'reduction of pain' and to be used for 'therapy' in patients with functional abdominal pain associated with IBS. It is not described as a device that collects or analyzes data to make a diagnosis.
No
The device description explicitly lists hardware components such as the TEA Device (which is battery-operated and contains a microprocessor, electric pulse generator, and power management module), lead cable, USB charging cable, USB power adapter, electrode pads, and holding clip. While it includes a software component (TEA IBS app), it is not solely software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
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 for diagnosis, monitoring, or screening.
- Device Function: The Transcutaneous Electrical Applicator (TEA) is a transcutaneous electrical nerve field stimulator. It applies electrical stimulation to specific nerves on the body.
- Intended Use: The intended use is to reduce pain associated with IBS by stimulating nerves. This is a therapeutic intervention, not a diagnostic test performed on a specimen.
- Device Description: The description details the electrical components and how it delivers electrical pulses. There is no mention of analyzing biological samples.
The device is a therapeutic device that delivers electrical stimulation to the body, which falls outside the scope of In Vitro Diagnostics.

Device Description
The TEA Device is a non-invasive, battery-operated, prescription-based transcutaneous electrical nerve field stimulator indicated for use in adult patients with functional abdominal pain associated with the irritable bowel syndrome (IBS).
The system includes the following components: TEA Device, lead cable, USB charging cable, USB power adapter, electrode pads, holding clip, and TEA IBS app. The device can be used in clinical environments (i.e., outpatient clinics and hospitals) and/or at home.
The TEA Device is powered by an internal rechargeable lithium polymer battery and uses a microprocessor to control the working modes, the waveform and strength of the output pulse. The electric pulse generator is based on a current source circuit. The power management module contains a DC-DC boost conversion circuit that provides the required voltage for the electric pulse generator. The TEA Device is able to connect with the TEA IBS app, which is located on a smartphone. The user interface is available on both the TEA Device and TEA IBS app. The user can power on/off the device, adjust treatment time and treatment intensity. Treatment time is adjustable within the of range 5~240 minutes per treatment session with a maximal operating time of 8.6 hours per day. In addition, there is over-load, over-current and no-load protection as well as an automatic shut-off function. The Bluetooth transceiver module is responsible for communication between the TEA Device and TEA IBS app located on a smartphone.

Summary of Performance Studies
Data from a randomized sham-controlled clinical study is submitted to support the safety and efficacy of the TEA Device. A total of 42 patients (32 female and 10 male) with IBS-C were recruited and randomly allocated to: 1) 4-week TEA therapy group or 2) 4-week sham-TEA therapy group. 21 patients were recruited, with 2 patients in the sham-TEA therapy group dropping out during the study, so only 19 patients completed the study in the sham-TEA therapy group. Constipation was evaluated using the complete spontaneous bowel movements (CSBMs) per week and Bristol stool form scale (BSFS), while the abdominal pain was measured using the visual analog scale (VAS).
Evaluations of constipation and abdominal pain were performed at baseline and after the 4-week therapy with either therapy performed daily for 1 hour (30 minutes in the morning and 30 minutes in the evening), with two TEA electrode pads applied bilaterally at the auricular cymba concha (one electrode on each cymba concha) and two TEA electrode pads applied bilaterally at the sham location of elbow area (one electrode on each elbow).
After the 4-week period, the number of CSBMs/week in the TEA group tripled in comparison with the sham-TEA group (2.8 ± 2.2 vs. 0.9 ± 0.9, P

- 1.6 Summary of Substantial Equivalence Comparison to the Predicate Device
The subject device has the same intended use and similar technological characteristics as the predicate device. A minor population difference in the indication (modification in the patient population from pediatric to adult) does not alter the intended use and does not affect the device's safety and efficacy. The reference device was selected to support scientific methodology or standard reference values. The comparison of the subject device with the predicate and reference devices is shown in Table 1.
