Intended Use

The Flowable Wound Matrix is intended for the management of wounds including: partial and full-thickness wounds, pressure ulcers, venous ulcers, diabetic ulcers, chronic vascular ulcers, tunneled/undermined wounds, surgical wounds (donor sites/grafts, post-Moh's surgery, post-laser surgery, podiatric, wound dehiscence), trauma wounds (abrasions, lacerations, 2nd degree burns, skin tears) and draining wounds.

Device Description

The Flowable Wound Matrix is a wound management device consisting of particulate Porcine Small Intestinal Submucosa (SIS) and fructose, a natural carrier. The device is an addition to the family of SIS-based wound management devices (Oasis Wound Matrix (K061711) and Cook ECM Powder (K152033)) already manufactured by Cook Biotech Incorporated. The device is supplied dry, rehydrated with saline at the time of application, and delivered topically to the wound through a pre-supplied syringe. SIS, which composes the majority of the device, is the same base material as that of the predicate device Oasis Wound Matrix (K061711) and reference device Cook ECM Powder (K152033). In addition to SIS, the device also contains fructose, a carrier added only to facilitate the preparation and delivery of the device. Fructose is a sugar naturally found in the body and is readily metabolized. The Flowable Wound Matrix is meant to be employed by the user to manage wounds of the types outlined in the intended use of the device. The device achieves its intended use by providing a scaffold for cellular invasion and capillary growth, and maintaining a supportive environment for wound management.

AI/ML Overview

I am sorry, but the provided text only contains a 510(k) summary for the "Flowable Wound Matrix" device. It outlines the device description, its intended use, comparison to predicate/reference devices, and a summary of non-clinical tests conducted for substantial equivalence.

However, the document does not contain the specific details required to answer your request regarding acceptance criteria and a study proving the device meets them. Specifically, it lacks:

  1. A table of acceptance criteria and reported device performance. It only lists performed tests (biocompatibility, rehydration and deployment, package integrity, shelf life, collagen characterization).
  2. Sample sizes used for a test set, data provenance, or details about ground truth establishment.
  3. Information on the number of experts or adjudication methods.
  4. Any mention of a multi-reader multi-case (MRMC) comparative effectiveness study or standalone algorithm performance.
  5. Sample size for a training set or how ground truth for a training set was established.

This document is focused on demonstrating substantial equivalence to a predicate device, primarily through non-clinical bench testing and comparison of features, rather than presenting a clinical study with detailed performance metrics against specific acceptance criteria.

Predicate Device:

Oasis Wound Matrix (K061711)

Reference Devices:

Integra Flowable Wound Matrix (K072113) Cook ECM Powder (K152033) MicroMatrix (K153754)

Intended Use:

The Flowable Wound Matrix is intended for the management of wounds including: partial and full-thickness wounds, pressure ulcers, venous ulcers, diabetic ulcers, chronic vascular ulcers, tunneled/undermined wounds, surgical wounds (donor sites/grafts, post-Moh's surgery, post-laser surgery, podiatric, wound dehiscence), trauma wounds (abrasions, lacerations, 2nd degree burns, skin tears) and draining wounds.

Device Description:

The Flowable Wound Matrix is a wound management device consisting of particulate Porcine Small Intestinal Submucosa (SIS) and fructose, a natural carrier. The device is an addition to the family of SIS-based wound management devices (Oasis Wound Matrix (K061711) and Cook ECM Powder (K152033)) already manufactured by Cook Biotech

{4}------------------------------------------------

Incorporated. The device is supplied dry, rehydrated with saline at the time of application, and delivered topically to the wound through a pre-supplied syringe. SIS, which composes the majority of the device, is the same base material as that of the predicate device Oasis Wound Matrix (K061711) and reference device Cook ECM Powder (K152033). In addition to SIS, the device also contains fructose, a carrier added only to facilitate the preparation and delivery of the device. Fructose is a sugar naturally found in the body and is readily metabolized. The Flowable Wound Matrix is meant to be employed by the user to manage wounds of the types outlined in the intended use of the device. The device achieves its intended use by providing a scaffold for cellular invasion and capillary growth, and maintaining a supportive environment for wound management.

Comparison to Predicate Device:

The subject and predicate devices share the same fundamental technology; the main components of both devices are porcine SIS. The main difference between the subject and predicate is the device configuration and method of application. The Oasis Wound Matrix is supplied as a dry sheet of SIS and is applied topically by rehydrating and placing the sheet directly onto a wound. The Flowable Wound Matrix, in contrast, is particulate SIS supplied dry in a cylindrical shape. Upon rehydration with saline, the device acquires a gel-like consistency and can be applied directly to the wound site using the supplied syringe.

Summary of Non-Clinical Tests:

The following testing was performed to demonstrate substantial equivalence:

  • Biocompatibility Testing:
    • o Cytotoxicity
    • o Sensitization
    • Irritation/Intracutaneous Reactivity O
    • O Acute Systemic Toxicity
  • Other Testing: ●
    • Rehydration and Deployment o
    • o Package Integrity
    • Shelf Life o
    • Collagen Characterization (Western Blot and Digital Scanning o Calorimetry)

{5}------------------------------------------------

Substantial Equivalence:

Table 5-1 provides a comparison of the subject and predicate devices.

To provide further evidence of substantial equivalence, CBI used the 510(k) Decision-Making Flowchart from the FDA guidance document Evaluating Substantial Equivalence in Premarket Notifications [510(k)] (July 28, 2014) to compare and assess the intended use and the technological characteristics of the subject and predicate devices. Specifically, the intended uses of both devices are identical. In terms of technological characteristics, while the subject device differs from the predicate device in form (sheet vs. flowable), both devices share the same underlying technology, namely topical application of porcine SIS for wound management. In this 510(k), CBI submits biocompatibility, deployment, package and shelf-life testing as evidence to demonstrate the device can function as intended and performs comparably to the predicate device that is currently marketed for the same intended use. In conclusion, CBI believes the Flowable Wound Matrix is substantially equivalent to the Oasis Wound Matrix based on success in non-clinical testing and the identical nature of the fundamental technology and intended use.
