Intended Use
The Renasys EZ is indicated for patients who would benefit from a suction device (negative pressure) as it may promote wound healing via the removal of fluids, including irrigation and body fluids, wound exudates and infectious materials. Examples of appropriate wound types include: Chronic, Acute, Traumatic, Sub-Acute and dehisced wounds, Ulcers (such as pressure or diabetic), Partial-thickness burns, Flaps and Grafts.
Device Description
The RENASYS™ EZ NPWT device is a lightweight, portable suction device intended to deliver negative pressure to a wound at a range of pressure settings via a tube set connected to a wound dressing. The suction pump creates negative pressure and removes exudates from the wound site to a disposable canister. The device can operate either by a mains power supply or internal battery. Renasys EZ is suitable for use in both a hospital and homecare setting. RENASYS™ EZ is compatible with existing Smith & Nephew wound dressing kits currently on the market.
More Information

No
The document describes a standard negative pressure wound therapy device and does not mention any AI or ML capabilities.

Yes
The device is indicated for patients who would benefit from a suction device that may promote wound healing, which is a therapeutic purpose.

No
The device description and intended use clearly state that it is a suction device for wound healing and fluid removal, which are therapeutic functions, not diagnostic ones. It does not analyze conditions or collect diagnostic information.

No

The device description explicitly states it is a "lightweight, portable suction device" with a "suction pump" and operates via "mains power supply or internal battery," indicating it is a hardware device.

Based on the provided information, the Renasys EZ is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly describes a device that applies negative pressure to a wound to remove fluids and promote healing. This is a therapeutic intervention applied directly to the patient's body, not a test performed on a sample taken from the body to diagnose a condition.
  • Device Description: The description details a suction pump, tubing, and a canister for collecting exudates. This aligns with a wound therapy device, not a diagnostic device that analyzes biological samples.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (like blood, urine, tissue, etc.), reagents, or any process related to diagnosing a disease or condition based on in vitro analysis.

Therefore, the Renasys EZ falls under the category of a therapeutic medical device, specifically a Negative Pressure Wound Therapy (NPWT) system, rather than an In Vitro Diagnostic device.

Dear Ms. Reynolds:

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 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); medical device reporting (reporting of medical device-related adverse events) (21 CFR 803); 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.
