The RENASYS EZ MAX NPWT is indicated for patients who would benefit from a suction device (negative pressure wound therapy) as it may promote wound healing via removal of fluids, including irrigation and body fluids, wound exudates and infectious materials. Appropriate wound types include: Chronic, Acute, Traumatic, Sub-acute and dehisced wounds, Ulcers (such as pressure or diabetic), Partial-thickness burns, Flaps and grafts. RENASYS EZ MAX professional healthcare facility model (REF 66801309) is intended for use in acute care settings and other professional healthcare environments where product use is conducted by or under the supervision of a qualified healthcare professional.
The RENASYS™ Foam and Gauze NPWT Wound Dressing Kits with Soft Port are intended to be used in conjunction with Smith & Nephew NPWT (Negative Pressure Wound Therapy) systems. Smith & Nephew RENASYS systems are indicated for patients who would benefit from a suction device (negative pressure wound therapy) as it may promote wound healing via the removal of fluids, including irrigation and body fluids, wound exudates and infectious materials. Appropriate wound types include: chronic, acute, traumatic, sub-acute and dehisced wounds, ulcers (such as pressure or diabetic), partial-thickness burns, flaps and grafts.
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.
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.
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.
The provided document is a 510(k) premarket notification for a medical device. It details the device description, indications for use, comparison with predicate devices, and non-clinical tests conducted to demonstrate substantial equivalence. However, it does not contain information about the device's performance in terms of specific acceptance criteria, corresponding study results, or aspects typically associated with an AI/ML medical device such as sample sizes for test/training sets, data provenance, expert adjudication, or MRMC studies.
Therefore, I cannot fulfill your request for:
- A table of acceptance criteria and the reported device performance: The document does not define specific acceptance criteria (e.g., sensitivity, specificity, accuracy thresholds) or present quantitative performance results against such criteria for the device. Instead, it states that "comprehensive verification was completed which demonstrated acceptable device performance" or that certain aspects are "substantially equivalent" to predicate devices.
- Sample size used for the test set and the data provenance: Not mentioned.
- Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not mentioned, as no ground truth determination by experts is described.
- Adjudication method for the test set: Not mentioned.
- If a multi-reader multi-case (MRMC) comparative effectiveness study was done, and the effect size: Not mentioned.
- If a standalone (i.e., algorithm only without human-in-the-loop performance) was done: Not mentioned, as this is not an AI/ML device.
- The type of ground truth used: Not applicable in the context of this device's testing. Testing focused on device functionality, materials, and safety (e.g., pumping capacity, alarm functionality, biocompatibility).
- The sample size for the training set: Not applicable, as this is not an AI/ML device.
- How the ground truth for the training set was established: Not applicable.
What the document does provide regarding testing and "acceptance" (or rather, verification of design specifications and substantial equivalence):
The document details various non-clinical (bench) tests conducted to verify that modifications to the RENASYS EZ MAX NPWT device and the RENASYS Foam and Gauze NPWT Wound Dressing Kits with Soft Port meet design specifications and demonstrate substantial equivalence to predicate devices. These tests relate to the functional performance, safety, and material characteristics of the device.
Table summarizing verification activities (from the "Verification Testing Performed" column):
| Modification | Verification Testing Performed (Indicative of "Acceptance") |
|---|---|
| Addition of RENASYS EZ MAX 800ml S-Canister without Solidifier | Comprehensive verification was completed which demonstrated acceptable device performance. |
| Modification to half of the bacterial overflow guard housing material to a softer resin | Comprehensive verification was completed which demonstrated acceptable device performance and improved usability. |
| Qualification of a replacement resin for the RENASYS EZ PLUS/EZ MAX 250ml S-Canister | Qualification studies demonstrated acceptable replacement of the resin. |
| Reduction in the amount of solidifier in the RENASYS EZ PLUS/EZ MAX 800ml S-Canister | Comprehensive verification was completed which demonstrated acceptable device performance. |
