No
The description focuses on hardware control, fixed parameters, and safety features based on impedance measurements. There is no mention of adaptive algorithms, learning from data, or any typical AI/ML terminology.
Yes
The "Intended Use / Indications for Use" section explicitly states that "Treatment with the TESA device is intended to reduce the symptoms of depression, anxiety and insomnia," which are therapeutic goals.
No
The device description clearly states that the TESA device is intended for "Treatment with the TESA device is intended to reduce the symptoms of depression, anxiety and insomnia." It describes how it delivers electrotherapy, not how it diagnoses conditions.
No
The device description clearly outlines hardware components including electrodes, a microprocessor, a display, and circuitry for delivering and monitoring electrical current. It also mentions hardware verification and validation.
Based on the provided information, the TESA device is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use is to "reduce the symptoms of depression, anxiety and insomnia." This is a therapeutic use, not a diagnostic one. IVD devices are used to examine specimens from the human body to provide information for diagnosis, monitoring, or screening.
- Device Description: The device delivers electrical current to the patient's head. This is a direct interaction with the patient's body for treatment purposes. IVD devices analyze samples outside the body.
- No mention of analyzing biological samples: The description focuses on the electrical stimulation and safety features related to electrode contact and current delivery. There is no mention of collecting or analyzing blood, urine, tissue, or any other biological specimen.
Therefore, the TESA device falls under the category of a therapeutic medical device, not an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
Treatment with the TESA device is intended to reduce the symptoms of depression, anxiety and insomnia.
The TESA device is intended for use by or on the order of a licensed health care practitioner. A trained technician will administer actual treatment.

Device Description
The TESA is a transcranial electrotherapy stimulation device. Three electrodes are applied, one to the forehead and one behind each ear. TESA delivers low amplitude AC current for a desired time of 0 to 99:59 minutes. Treatment can be stopped by pressing the "current off" button. Either the operator or patient may press this button at any time. During treatment, peak current amplitude can be adjusted over the available range of 0 - 4 mA. Treatment parameters are monitored and controlled by a built in microprocessor. The display on the front of TESA indicates remaining treatment time and shows the current setting.
During treatment, a modulated high frequency square wave is delivered to the patient electrodes. The amplitude and duration of the positive and negative going portions of this waveform have been carefully designed to deliver no DC component. Moreover, the electrodes are AC coupled to the patient to insure no DC component in the event of device failure.
Additional safety features of the TESA device include rapid measurement of electrode impedance to insure good electrode contact and to maintain controlled current output over changing load conditions (e.g. when electrode contact changes). Detection of poor electrode contact causes the device to stop treatment and illuminate an electrode fault LED. Further treatment is blocked until electrode/skin impedance is restored to nominal range.

(vi) The labeling for the device must include the following:
(A) The intended use population and the intended use environment;
(B) A warning that patients should be monitored by their physician for signs of worsening;
(C) A warning that instructs patients on how to mitigate the risk of headaches, and what to do should a headache occur;
(D) A warning that instructs patients on how to mitigate the risk of dizziness, and what to do should dizziness occur;

(2) Class III (premarket approval) when intended to treat depression.
(c) Date premarket approval application (PMA) or notice of completion of product development protocol (PDP) is required. A PMA or notice of completion of a PDP is required to be filed with the Food and Drug Administration on or before March 19, 2020, for any cranial electrotherapy stimulator device with an intended use described in paragraph (b)(2) of this section, that was in commercial distribution before May 28, 1976, or that has, on or before March 19, 2020, been found to be substantially equivalent to any cranial electrotherapy stimulator device with an intended use described in paragraph (b)(2) of this section, that was in commercial distribution before May 28, 1976. Any other cranial electrotherapy stimulator device with an intended use described in paragraph (b)(2) of this section shall have an approved PMA or declared completed PDP in effect before being placed in commercial distribution.

Dear Dr. Bartoo:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
