The description focuses on the mechanical principle of intermittent pneumatic compression and does not mention any AI/ML components or functionalities.
Yes
The device is intended to prevent DVT (Deep Vein Thrombosis) by improving blood velocity and promotes blood circulation, which are therapeutic effects for health conditions.
No
The device is a compression therapy device intended to prevent DVT and improve blood velocity, not to diagnose a condition.
No
The device description explicitly states it is comprised of an intermittent pneumatic controller, sleeves, and connectable hose, which are hardware components.
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 taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Device Function: The Compression Therapy Device LGT-2201DVT works by applying external pressure to the limbs to improve blood circulation. It does not analyze any biological samples taken from the patient.
- Intended Use: The intended use is to prevent DVT and treat conditions related to poor circulation by physically manipulating the limbs.
- Device Description: The description clearly outlines a mechanical process of inflating and deflating sleeves.
- Lack of IVD Indicators: There is no mention of analyzing samples, reagents, or any other components typically associated with IVD testing.
Therefore, the LGT-2201DVT is a therapeutic device that acts externally on the body, not an in vitro diagnostic device.

Dear Jet Li:
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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmr/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
