Applied to wound surfaces, it provides a moist environment and acts as a scaffold for cellular infiltration and capillary growth. The device is intended for use by clinicians in the management of various wound types. It may be cut to size and hydrated with saline or autologous body fluids. As the dressing degrades, it supports natural wound healing processes. The device is identical to the predicate K210949, with the current submission adding labeling instructions for hydration with autologous fluids. ## Clinical Evidence No clinical testing was required for this submission. Safety and effectiveness were established through non-clinical bench testing, including biocompatibility (ISO 10993), sterilization validation (ISO 14937), packaging validation, and performance testing (hydration, dimensional stability, handling). ## Technological Characteristics Porous matrix of chitosan (shellfish-derived) and sodium chondroitin sulfate. Biodegradable scaffold. Sterilized via ethylene oxide (ISO 10993-7). Biocompatibility per ISO 10993-1:2018. Packaging validated per ANSI/AAMI/ISO 11607-1, ASTM D4169, ASTM F2096, ASTM F88. ## Predicate Devices - Foundation Dermal Regeneration Scaffold (DRS) Solo ([K210949](/device/K210949.md)) - NovoSorb BTM Wound Dressing ([K172140](/device/K172140.md)) - Meso Wound Matrix ([K112888](/device/K112888.md)) ## Reference Devices - Medeor™ Matrix ([K103787](/device/K103787.md)) - RegenKit®-Wound Gel-2 (BK210661) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading. 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. {1}------------------------------------------------ Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

The chitosan- glycosaminoglycan biodegradable, porous matrix provides a scaffold for cellular invasion and capillary growth. The device is applied on the surface of the wound, and provides a moist wound environment. The dressing may be replaced or may remain in place, acting as a scaffold to promote cellular infiltration and capillary growth as the dressing degrades. The Foundation DRS Solo is identical to the predicate cleared in K210949. ### INDICATIONS FOR USE Foundation DRS Solo is indicated for the management of wounds including: - . Full thickness and partial thickness wounds - Pressure ulcers ● - Venous ulcers ● - Ulcers caused by mixed vascular etiologies ● - Diabetic ulcers ● - Partial thickness burns (superficial second-degree burns) - Donor sites and other bleeding surface wounds ● - Abrasions ● - Trauma wounds (abrasions, lacerations, skin tears) ● - . Dehisced wounds - Surgical wounds (donor sites/grafts, post-Moh's surgery, post-laser surgery, ● podiatric, wound dehiscence) Foundation DRS Solo may be cut to size. # COMPARISON OF TECHNOLOGICAL CHARACTERISTICS Bionova Medical Inc. believes that the Foundation DRS Solo is substantially equivalent to the predicate devices based on the information summarized here: The subject device has the same design and dimensions and uses identical materials as the devices cleared in K210949. The subject device has the same intended use and technological characteristics as the devices cleared in K210949. The only difference is an update to the labeling to include an option to moisten the device with autologous body fluids. This information is provided in the event the user chooses to hydration fluids other than saline and does not affect the intended use, the technological characteristics, or the principle of operation of the device. The technological characteristics of the Foundation DRS Solo have undergone testing to ensure the device is as safe and effective as the primary predicate. {6}------------------------------------------------ # SUMMARY OF NON-CLINICAL TESTING The following tests were performed on the subject device to demonstrate safety based on current industry standards: - Hydration . - Dimensional stability ● - Handing characteristics . In addition, since the subject and primary predicate devices have identical indications for use and technological characteristics, the following tests were leveraged from K210949: - Biocompatibility: Biocompatibility testing was conducted in accordance with ISO 10993-1:2018. The subject device was evaluated for: - Cytotoxicity per ISO 10993-5 - - Intracutaneous Study in Rabbits per ISO 10993-10 - - -Guinea Pig Max Sensitization per ISO 10993-10 - Acute Systemic Toxicity in Mice per ISO 10993-11 - - Material-Mediated Rabbit Pyrogen Study per ISO 10993-11 and USP <151> - - Bacterial Reverse Mutation per ISO 10993-3 - - Genotoxicity Mouse Lymphoma Assay per ISO 10993-3 - - Systemic Toxicity Study with Full Thickness Skin Breach- 28 Days in Rats per ISO -10993-11 and ISO 10993-6 - Chemical Characterization per ISO 10993-18 - - Sterilization: ● Sterilization validation was performed in accordance with the following standards: - Sterilization validation per ISO 14937 - - Bacterial Endotoxins Testing (LAL) per AAMI ST72 - - Ethylene oxide sterilization residuals per ISO 10993-7 - - Packaging: Packaging validation testing was performed according to the following standards: - ANSI/AAMI/ISO 11607-1 - - ASTM D4169 - - ASTM F2096 - - ASTM F88 - - Performance Testing: ● - Wound Healing Study in a Porcine Model - - Functionality Testing on Aged Devices - - Viral Inactivation was leveraged from the device previously cleared in K123961. The chitosan used in the subject device is identical and from the same supplier as the device cleared in K123961. {7}------------------------------------------------ The results of these tests indicate that the Foundation DRS Solo is substantially equivalent to the primary predicate device. ## SUMMARY OF CLINICAL TESTING Clinical testing was not required for the labeling update to include moistening of the device by autologous bodily fluids, in addition to saline. ### CONCLUSION The Foundation DRS Solo is the same device as the primary predicate device cleared in K210949, with the only change being a labeling change to include the addition of autologous body fluids as possible hydration fluids. Based on the testing performed, including hydration, dimensional stability as well as handling, it can be concluded that the subject device does not raise new questions of safety or effectiveness compared to the predicate devices. The similar intended use, technological characteristics, and performance characteristics of the subject device are considered substantially equivalent to the predicate devices. --- **Source:** [https://fda.innolitics.com/device/K231937](https://fda.innolitics.com/device/K231937) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
