The device description details a standard electrical stimulator with pre-set programs and user-selectable parameters. There is no mention of AI, ML, or any adaptive or learning capabilities. The comparison to a predicate device with identical circuitry further suggests a traditional, non-AI/ML approach.
Yes
The device is intended for the temporary relief of pain and to stimulate healthy muscles to improve performance, which are therapeutic claims.
No
The device is intended for pain relief and muscle stimulation, not for diagnosing medical conditions.
No
The device description explicitly states it is a "precision Class II device housed in a sturdy lightweight cabinet" and is supplied with hardware components like a control unit, skin electrodes, batteries, and cables. This indicates it is a hardware device with embedded software, not a software-only medical device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states the device is for the temporary relief of pain and muscle stimulation. These are therapeutic applications, not diagnostic ones.
- Device Description: The description details a device that delivers electrical stimulation through skin electrodes. This is consistent with a TENS/NMES device, which is used for physical therapy and pain management, not for analyzing samples from the human body.
- No mention of biological samples: There is no indication that the device interacts with or analyzes any biological samples (blood, urine, tissue, etc.), which is a defining characteristic of IVD devices.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.

Device Description
The Applicant device, XiniWave II Model ECS322P, is a precision Class II device housed in a sturdy lightweight cabinet. The keypad controls and the circuit for the Applicant device are identical to the Predicate. For a maturing user constituency, the cabinet of the Applicant device is larger than the Predicate with a bigger white paper Liquid Crystal Display (LCD), yet the weight of the device is virtually equivalent. The Applicant device is powered by 3 x 1.5V AAA alkaline batteries. The Applicant device offers the user a choice of eight (8) pre-set Transcutaneous Electro Neuro Stimulation (TENS) programs for the temporary relief of pain (80 mA Max.) and one pre-set Neuro-Muscular Electrical Stimulation (NMES) program for muscle conditioning (90 mA Max.). In the NMES mode of operation the user is able to select work/rest stimulation with pulse rates between 2-100Hz and pulse widths between 50-450uS rate may be selected. The mode of action for the Applicant device in TENS or NMES mode is identical to the mode of action to the Predicate.
The Applicant device is supplied with skin electrodes (electrode surface minimum of 25cm -), to stimulate the patient. The skin electrodes (extant for the industry) are the same ones as supplied with the Predicate and delineated in the User's Manual. The Applicant device control unit connects directly to the skin electrode by cable and plug (extant for the industry).

by remote radio frequency signals. The product firmware is written in a secure (proprietary) code.
The skin electrode in the Applicant device is identical to the Predicate device. The Applicant device control unit connects directly to the skin electrode by cable and plug (design extant for the industry).
Water-resistance is designed into the unit for EU mandated performance requirements per IEC 60601-2-11:2013 only. To the Applicants knowledge, it is not the custom to use any device of this type in wet areas. The Applicant is in complete agreement with FDA guidance not to use the device in wet areas. Hence, the Applicant device will not be promoted as water-resistant nor labelled as such per this 510(k) submission.
The manual of the Applicant and Predicate devices are printed in English. The Applicant device is available in Spanish test is available on request. The languages used in the Applicant device have been selected based on the predominant languages spoken in the United States and Commonwealth of Puerto Rico and then cross-referenced with the cumulative immigration data selecting the three largest languages spoken by immigrant populations to enter theses United States over the past 50 years (1965 to 2015). As such the device labelling complies with or exceeds 21 CFR 801.15(a)(6)(3)(c)(1)(2)& (3).
The Risk Assessment prepared by an independent firm and reviewed by independent commentators, in accordance with the Quality System Regulation (including documentation of design inputs. risk analysis, design output, test procedures, verification and validation procedures, and documentation of formal design reviews) demonstrate that the product modifications are as safe, and effective, and that the Applicant device performs as well as the Predicate device [21 CFR 807.92(b)(3)].
The Applicant device uses the identical pre-set NMES programs as the Predicate device and such, the out-put, in the applicable NMES programs is substantially equivalent as demonstrated in Section 5.0 Table 4 below.

Therefore, since the device modifications do not affect the intended use of the device or alter the fundamental scientific technology of the device concordant with the uses described under 21CFR 882.5890 OTC and for muscle conditioning as described under 21CFR 890.5850 OTC: Powered Muscle Stimulator (i.e., Indications for Use unchanged from the Predicate) and the Quality Assurance paradigm, including Risk, demonstrates that the product modifications are as safe, and effective, and performs as well as or better than the Predicate device. As such the Applicant device and does not raise new questions about safety or effectiveness and demonstrates with reasonable assurance based on established controls that the device is at least as safe and effective as a legally marketed device.
Conclusion
- . The Applicant device is substantially equivalent to the predicate because it has the same intended therapeutic use as the Predicate described under 21CFR 882.5890 OTC: Stimulator, Nerve, Transcutaneous for Pain Relief and 21CFR 890.5850 OTC: Powered Muscle Stimulator:
- The Applicant device has the similar technological characteristics as the Predicate and that any differences do not adversely impact the safety or effectiveness of the Applicant device;
- The therapeutic labelling of the Applicant device is concordant with the Predicate and
