Intended Use
The WizAir DVT™ is a prescriptive device that induces Continuous Enhanced Circulation Therapy of the lower limbs. The WizAir DVT™ is intended for use in: Preventing Deep Vein Thrombosis (DVT). Enhancing blood circulation. Diminishing post-operative pain and swelling. Reducing wound-healing time. Treatment and assistance in healing: stasis dermatitis; venous stasis ulcers; arterial and diabetic leg ulcers. Treatment of chronic venous insufficiency. Reducing edema.
Device Description
The WizAir DVT™ is a prescriptive, pneumatic compression device designed to apply sequential compression to the lower limb. The control unit of the WizAir DVT™ is light and compact, thus making it a portable ambulant system. The WizAir DVT™ provides the user with an option of battery operation in addition to the operation from the mains option. The WizAir DVT™ is easy to use and provides the user with several treatment options: compression of the foot -- single or double (either regular foot or foot booster), compression of the calf - single or double, compression of the Thigh -- single or double, and combined compression of any combination of two cuffs. The foot compression program is sequential intermittent pressure pulse application to a single celled foot cuff. The calf and thigh compression program is a sequential intermittent gradient application of a pressure to a three-celled calf cuff.

No
The description focuses on pneumatic compression and sequential pressure application, with no mention of adaptive algorithms, learning, or data-driven decision making that would indicate AI/ML. The "Mentions AI, DNN, or ML" section explicitly states "Not Found".

Yes
The device is intended for preventing Deep Vein Thrombosis (DVT), enhancing blood circulation, diminishing post-operative pain and swelling, reducing wound-healing time, and treating various venous and arterial conditions. These are all therapeutic applications.

No

The device is a prescriptive, pneumatic compression device designed for therapeutic purposes (preventing DVT, enhancing blood circulation, reducing pain/swelling, etc.), not for diagnosing conditions.

No

The device description explicitly mentions a "control unit," "pneumatic compression device," "battery operation," and "cuffs," indicating it is a hardware device with software control, not a software-only device.

Based on the provided information, the WizAir DVT™ is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. The WizAir DVT™ is a physical device that applies pneumatic compression to the lower limbs.
  • The intended use and device description clearly state that the WizAir DVT™ is a prescriptive, pneumatic compression device used for physical therapy and circulation enhancement. It does not involve the analysis of biological samples.

Therefore, the WizAir DVT™ falls under the category of a therapeutic or physical medicine device, not an in vitro diagnostic device.

Substantial Equivalence: Statement

The modified WizAir DVT™ System is substantially equivalent in all aspects. e.g., technological characteristics, modes of operation, performance characteristics, intended use, etc., to the commercially available WizAir DVT™. The modified WizAir DVT™ System includes an additional cuff -- the Foot Booster cuff for faster inflation of the cell.

The pressure profile of the new cuff is similar to that of the A-V Impulse System. Moreover, the additional cuff and software modification were verified through bench testing and validated through clinical analysis that was performed on healthy volunteers.

Testing results showed that the Foot Booster performs according to its specifications in safe and effective manner.

Performance Data:

A series of safety and performance testing including bench testing and clinical comparison between the Foot Booster cuff of the WizAir DVT™ and its predicate device demonstrated that the modified WizAir DVT™ System is substantially equivalent to its predicate devices without raising new safety and/or effectiveness issues

Dear Mr. Hacohen:

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.
