The document does not mention AI, ML, or any related concepts like deep learning, neural networks, or algorithms that adapt or learn. The description focuses on standard medical device components and functionalities.
Yes
The "Intended Use / Indications for Use" section explicitly states that the device is "indicated for use in applying therapeutic deep heat in body tissues for the treatment of selected medical conditions, including relief of pain, muscle spasms, and joint contractures."
No
Explanation: The device is described as a "Shortwave Therapy Unit" intended for applying "therapeutic deep heat" to treat conditions like pain, muscle spasms, and joint contractures. Its purpose is treatment, not diagnosis.
No
The device description explicitly states it consists of a "main unit and a standard applicator" and mentions hardware specifications like "output power of 80 W" and operating frequency, indicating it is a physical hardware device, not software-only.
Based on the provided information, the SW-180 is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use clearly states that the SW-180 is used for "applying therapeutic deep heat in body tissues for the treatment of selected medical conditions." This describes a therapeutic device that acts directly on the patient's body.
- Device Description: The description details a "Shortwave Therapy Unit" that uses radiofrequency energy to generate heat. This is consistent with a physical therapy or therapeutic device, not a device that analyzes samples from the body.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), performing tests on these samples, or providing diagnostic information based on such analysis.
IVD devices are specifically designed to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. The SW-180's function is to deliver therapeutic energy to the body.

Intended Use / Indications for Use
The SW-180 is indicated for use in applying therapeutic deep heat in body tissues for the treatment of selected medical conditions, including relief of pain, muscle spasms, and joint contractures.

§ 890.5290 Shortwave diathermy.
(a)
Shortwave diathermy for use in applying therapeutic deep heat for selected medical conditions —(1)Identification. A shortwave diathermy for use in applying therapeutic deep heat for selected medical conditions is a device that applies to specific areas of the body electromagnetic energy in the radiofrequency (RF) bands of 13.56 megahertz (MHz) or 27.12 MHz and that is intended to generate deep heat within body tissues for the treatment of selected medical conditions such as relief of pain, muscle spasms, and joint contractures, but not for the treatment of malignancies.(2)
Classification. Class II (performance standards).(b)
Nonthermal shortwave therapy —(1)Identification. A nonthermal shortwave therapy is a prescription device that applies to the body pulsed electromagnetic energy in the RF bands of 13.56 MHz or 27.12 MHz and that is intended for adjunctive use in the palliative treatment of postoperative pain and edema of soft tissue by means other than the generation of deep heat within body tissues as described in paragraph (a) of this section.(2)
Classification: Class II (special controls). The device is classified as class II. The special controls for this device are:(i) Components of the device that come into human contact must be demonstrated to be biocompatible.
(ii) Appropriate analysis/testing must demonstrate that the device is electrically safe and electromagnetically compatible in its intended use environment.
(iii) Non-clinical performance testing must demonstrate that the device performs as intended under anticipated conditions of use. Non-clinical performance testing must characterize the output waveform of the device and demonstrate that the device meets appropriate output performance specifications. The output characteristics and the methods used to determine these characteristics, including the following, must be determined:
(A) Peak output power;
(B) Pulse width;
(C) Pulse frequency;
(D) Duty cycle;
(E) Characteristics of other types of modulation that may be used;
(F) Average measured output powered into the RF antenna/applicator;
(G) Specific absorption rates in saline gel test load or other appropriate model;
(H) Characterization of the electrical and magnetic fields in saline gel test load or other appropriate model for each RF antenna and prescribed RF antenna orientation/position; and
(I) Characterization of the deposited energy density in saline gel test load or other appropriate model.
(iv) A detailed summary of the clinical testing pertinent to use of the device to demonstrate the effectiveness of the device in its intended use.
(v) Labeling must include the following:
(A) Output characteristics of the device;
(B) Recommended treatment regimes, including duration of use; and
(C) A detailed summary of the clinical testing pertinent to the use of the device and a summary of the adverse events and complications.
(vi) Nonthermal shortwave therapy devices marketed prior to the effective date of this reclassification must submit an amendment to their previously cleared premarket notification (510(k)) demonstrating compliance with these special controls.

Dear Dr. Athey:
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.
