The document describes a standard negative pressure wound therapy device and its accessories. There is no mention of AI, ML, or any features that would suggest the use of such technologies for data analysis, decision-making, or adaptive control. The performance studies focus on basic device functionality and equivalence to predicate devices.
Yes.
The device is indicated for promoting wound healing and is used for therapeutic purposes, such as removal of fluids and infectious materials from various wound types.
No
Explanation: The device is a suction device for wound healing and fluid removal, not for diagnosing conditions.
No
The device description clearly outlines a physical pump, canisters, and dressing kits, which are hardware components. The summary describes bench testing of the physical device's performance.
Based on the provided text, 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 about a person's health. This information is used for diagnosis, monitoring, or screening.
- Device Function: The RENASYS EZ MAX NPWT is a suction device used for wound management. It applies negative pressure to a wound to remove fluids and promote healing. It interacts directly with the wound surface, not with specimens taken from the body for analysis.
- Intended Use: The intended use clearly states it's for "patients who would benefit from a suction device (negative pressure wound therapy) as it may promote wound healing via removal of fluids...". This describes a therapeutic intervention, not a diagnostic test.
- Device Description: The description focuses on the mechanical function of applying negative pressure and collecting exudate. There is no mention of analyzing the collected fluids for diagnostic purposes.
Therefore, the RENASYS EZ MAX NPWT falls under the category of a therapeutic medical device, not an In Vitro Diagnostic device.

Device Description
RENASYS EZ MAX Negative Pressure Wound Therapy Device
The RENASYS EZ MAX Negative Pressure Wound Therapy NPWT device is a lightweight, suction device intended for wound management via application of continuous or intermittent negative pressure wound therapy to the wound for removal of fluids, including wound exudates, irrigation fluids, and infectious materials. The pump is connected to the wound dressing via a tube connected to a disposable canister. The device provides negative pressure wound therapy to the wound at a range of pressure settings and removes exudates from the wound site to the disposable canister. The device can operate either by a mains power supply or internal battery. The technological characteristics of the new device have not changed.
RENASYS Canisters
The 800ml and 250ml canisters are non-sterile, single use devices with a lid that is ultrasonically welded on. The canister kits contain a combination of solidifier gel pack, bacterial overflow quard that attaches to the pump and canister tubing that attaches to the Soft Port assembly.
The 800ml canister without solidifier is a non-sterile, single use device with a lid that is ultrasonically welded on. The canister kit contains a bacterial overflow guard that attaches to the pump and canister tubing that attaches to the Soft Port assembly.
RENASYS Foam and Gauze NPWT Wound Dressing Kits with Soft Port
The RENASYS Foam and Gauze Wound Dressing Kits with Soft Port consist of the following components:
Foam Kits: Polyurethane foam wound filler, a Soft Port assembly and transparent film drape. The foam kits are supplied sterile, single use and are offered in three sizes: small, medium and large.
Gauze Kits: Antimicrobial gauze wound filler, a Soft Port assembly, non-adherent wound contact layer, transparent film drape, saline bullet, No Sting Skin Prep and wound ruler. The Gauze kits are offered in four sizes: small, medium, large and extra-large. The individual components of the kit are packed sterile and kitted in a non-sterile kit package. The kit is single use.
The Soft Port assembly attaches to an exudate canister to deliver negative pressure wound therapy. The foam and gauze kits are designed specifically for use with the RENASYS negative pressure wound therapy devices and canisters.

Conclusions
In establishing substantial equivalence to the currently marketed predicate devices, Smith & Nephew, Inc. evaluated the indications for use, materials, technology, product specifications and energy requirements of the device. Performance testing, biocompatibility testing and electrical safety testing has been successfully completed to demonstrate that the RENASYS EZ MAX NPWT device and canisters, and the RENASYS Foam and Gauze NPWT Wound Dressing Kits with Soft Port are substantially equivalent to the predicate devices for the intended use.
