No
The description focuses on the mechanical function of negative pressure wound therapy and explicitly states that the operating principle, mechanism of action, and fundamental scientific technology are unchanged from the predicate device. There is no mention of AI or ML.
Yes
The device is clearly indicated for treating various types of wounds, including chronic and acute wounds, which aligns with the definition of a therapeutic device designed to alleviate or cure a medical condition.
No
The device is described as a "suction therapy unit" that provides localized negative pressure wound therapy to remove fluids and debris from wounds. Its purpose is to promote healing, not to diagnose a medical condition.
No
The device description explicitly states it is a "powered, portable suction device with battery backup" and includes a "vacuum air suction pump in the control unit," indicating it is a hardware device with integrated software, not a software-only medical device.
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 (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
- Device Function: The Carilex VT-200-i NX is a negative pressure wound therapy (NPWT) device. Its primary function is to apply suction to a wound to remove fluids and promote healing. It does not analyze or test biological specimens in vitro.
- Intended Use: The intended use is for treating various types of wounds by applying negative pressure and removing exudate. This is a therapeutic function, not a diagnostic one.
- Device Description: The description clearly outlines a mechanical process of applying suction and collecting fluids. There is no mention of analyzing these fluids for diagnostic purposes.
Therefore, the Carilex VT-200-i NX falls under the category of a therapeutic medical device, not an in vitro diagnostic device.

Device Description
Carilex VT 200-i NX is a powered, portable suction device with battery backup that provides localized negative pressure wound therapy when used with the VT Dressing kits to remove body fluids, irrigation fluids, infectious material and tissue debris from the wound.
Carilex VT 200-i NX have shown that they may help promote the healing of several different kind of wounds via fluid removal. When in use, the vacuum air suction pump in the control unit suck the air from the wound through the connecting hose and dressing to create a negative pressure environment of the wound. The suction of the pump will help remove excess fluids from the wound. VT Dressing kits will be placed onto the wound by healthcare professional and a tube will be connected from the wound to the canister on the pump. After the dressing and tube are correctly applied and connected, turn on the VT · 200 i NX device and set to the pressure setting that is prescribed by healthcare provider. The canister will then collect the excess fluid. This device is not intended for home use.
Carilex VT-200-i NX is an updated version of Carilex VT-100/VT-200 (K173407) via engineering change, and its software and hardware modifications are made to add instill function. The instillation mode is a modified continuous mode, where wound irrigation solution is simultaneously infused during negative pressure suction to assist in wound cleaning and removal of infectious substances. There has been no change to the operating principle, mechanism of action or fundamental scientific technology of the predicate device. The Carilex VT-200-i NX is developed with technology and components that are almost identical to Carilex VT·100/ VT·200.
Carilex VT-200-i NX use the same collection canisters as predicate, VT-100, and VT-200 that are supplied non-sterile, single-use with a volume capacity of 300 ml or 1000ml. The canister is permanently sealed to minimize the potential of users coming into contact with exudates. Two tubes with two connector attached to its distal end is attached to the canister, and this connector which can be provided with or without lock feature attaches to the corresponding tubing included in the Carilex VT Dressing Kits.

Operating Mode & Pressure setting
The general therapy modes, continuous and intermittent, of the all devices are the same, but proposed devices (VT 200-i NX) is with additional mode for instill. The instillation mode is a modified continuous mode, where wound irrigation solution is simultaneously infused during negative pressure suction to assist in wound cleaning and removal of infectious substances. This principle is similar to the predicate device 2 (Sved®) Simultaneous irrigation technology. The predicate device (SVED®) allows for the optional use of wound irrigation to the wound bed. During irrigation, the predicate device (SVED®) will provide higher pressure (-50 or -120 or -150 mmHg) and approximately -25 mmHg lower pressure.
Canister
The canister compatible with the proposed device (VT . 200-i NX) has undergone a mechanical design revision, incorporating additional tubing to accurately detect the pressure at the wound site.
EMC
The electric design of both device is the same, in addition, proposed devices (VT200-i NX) is compliance with the most updated standards.
10. Discussion of Non-Clinical Tests Performed for Determination of Substantial Equivalence are as follows:
This submission is to provide an update to the existing cleared Carilex VT · 100/ VT · 200. The subject and predicate devices are based on the following same technical elements:
- Continuous and Intermittent treatment modes with the addition of instillation mode in the subject device ●
- Pressure sensing technology within the pump ●
- Available for use with 300cc and 500cc, 1000cc canisters
- Use AC and Rechargeable battery
The following technological differences exist between the subject and predicate devices:
- The updated Carilex VT·200-i NX has an updated indications for use to include the removal of irrigation ● fluids via the application of negative pressure. This better aligns the indications for use with the "OMP" regulation definition.
- The updated Carilex VT 200-i NX has had other enhancements including:
- Canister with additional tubing to detect the pressure of wound site accuracy O
