No
The document does not mention AI, ML, or any related concepts in the device description, intended use, or performance studies.
Yes
The device is described as an "adjunctive therapy for the treatment of medical diseases and conditions" which directly implies a therapeutic use. The indications for use, such as relaxation of muscle spasms and prevention of disuse atrophy, also align with therapeutic applications.
No
The device is described as a powered muscle stimulator used for therapeutic purposes such as muscle relaxation, prevention of atrophy, and re-education. It applies electrical current for treatment, not for diagnosing conditions.
No
The device description explicitly states "Powered Muscle Stimulator, HT-311, HT-311N, HT-312", indicating a hardware component that delivers electrical current.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health.
- Device Function: The description clearly states the device applies an electrical current to electrodes on the patient's skin for therapeutic purposes (muscle stimulation). This is a direct interaction with the patient's body, not an analysis of a specimen taken from the body.
- Intended Use: The intended uses listed are all related to physical therapy and rehabilitation, not diagnostic testing of biological samples.
Therefore, this device falls under the category of a therapeutic medical device, specifically a Powered Muscle Stimulator, rather than an In Vitro Diagnostic.
N/A
Intended Use / Indications for Use
Specific indications: used to apply an electrical current to electrodes on patient's skin to function as:
- Relaxation of muscle spasms;
- Prevention or retardation of disuse atrophy
- Muscle re-education
- Immediate post-surgical stimulation of calf muscles to prevent venous thrombosis
- Maintaining or increasing range of motion.
- Clinical settings: The device should only be used under medical supervisions for adjunctive therapy for the treatment of medical diseases and conditions.

Trade/Device Name: Home Care Various Models of Powered Muscle Stimulator, HT-311, HT-311N, HT-312 Regulation Number: 21 CFR 890.5850 Regulation Name: Powered muscle stimulator Regulatory Class: II Product Code: IPF Dated: April 9, 2003 Received: April 14, 2003
Dear Mr. Cheng:
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. This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (301) 594-4659. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (301) 443-6597 or at its Internet address http://www.fda.gov/cdrh/dsma/dsmamain.html
