No reference devices were used in this submission.
No
The device description and performance studies focus on the material properties and delivery system of a wound matrix, with no mention of AI or ML.
Yes.
The device is intended for the management of various types of wounds, including chronic and surgical wounds, which aligns with the definition of a therapeutic device designed to treat or alleviate health conditions.
No
Explanation: The device description states it is a "wound dressing" intended for the "management of wounds" by providing a "protective environment for wound healing." This indicates a therapeutic, not diagnostic, function.
No
The device description explicitly details physical components like a wound matrix derived from porcine liver tissue, a delivery system with a guidewire and tamp tube, and an optional Introducer Set accessory. This indicates it is a physical medical device, not software-only.
Based on the provided information, the MiroTract Wound Matrix is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use is for the management of wounds, which is a therapeutic application directly on the patient's body. IVDs are used to examine specimens from the human body to provide information for diagnosis, monitoring, or screening.
- Device Description: The device is a wound dressing applied to the wound itself. It's a physical matrix designed to support healing. This is not consistent with the nature of IVD devices, which typically involve reagents, instruments, or software for analyzing biological samples.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples, detecting analytes, or providing diagnostic information based on laboratory testing.
Therefore, the MiroTract Wound Matrix falls under the category of a medical device used for wound management, not an In Vitro Diagnostic device.

Device Description
The Reprise Biomedical MiroTract device consists of the MiroTract Wound Matrix and disposable delivery system. The MiroTract Wound Matrix is a sterile, single use, noncrosslinked acellular wound dressing that is derived from porcine liver tissue. The porcine liver is perfusion decellularized resulting in a collagen matrix that is dried, cut to size, and radially compressed onto the guidewire of the MiroTract delivery system. The delivery system includes a guidewire and tamp tube to manually push the MiroTract Wound Matrix off the guidewire into a wound. The MiroTract Wound Matrix porous scaffold provides a protective environment for wound healing. The MiroTract Wound Matrix is provided in two diameters (3 mm and 5 mm) and two lengths (5 cm and 9 cm). The MiroTract device is packaged dry in a plastic tray placed inside a foil pouch. The device is terminally sterilized in its packaging by e-beam irradiation. An optional Introducer Set accessory consisting of a tearaway sheath and dilator is provided in a separately packaged sterile pouch that is placed in a shelf box along with a MiroTract packaged device.

Dear Kathy Herzog:
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 (the 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. 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.

III. PREDICATE DEVICE
Miro3D Wound Matrix (K223257). This predicate has not been subject to a design-related recall. No reference devices were used in this submission.
IV. DEVICE DESCRIPTION
The Reprise Biomedical MiroTract device consists of the MiroTract Wound Matrix and disposable delivery system. The MiroTract Wound Matrix is a sterile, single use, noncrosslinked acellular wound dressing that is derived from porcine liver tissue. The porcine liver is perfusion decellularized resulting in a collagen matrix that is dried, cut to size, and radially compressed onto the guidewire of the MiroTract delivery system. The delivery system includes a guidewire and tamp tube to manually push the MiroTract Wound Matrix off the guidewire into a wound. The MiroTract Wound Matrix porous scaffold provides a protective environment for wound healing. The MiroTract Wound
5
Matrix is provided in two diameters (3 mm and 5 mm) and two lengths (5 cm and 9 cm). The MiroTract device is packaged dry in a plastic tray placed inside a foil pouch. The device is terminally sterilized in its packaging by e-beam irradiation. An optional Introducer Set accessory consisting of a tearaway sheath and dilator is provided in a separately packaged sterile pouch that is placed in a shelf box along with a MiroTract packaged device.
V. INDICATIONS FOR USE
The MiroTract Wound Matrix is indicated for the following:
The MiroTract Wound Matrix is intended for the management of wounds including:
- . Partial and full thickness wounds
- Pressure ulcers ●
- Venous ulcers ●
- Chronic vascular ulcers ●
- Diabetic ulcers ●
- Tunneled, undermined wounds ●
- Trauma wounds (abrasions, lacerations, partial thickness burns, and skin tears) ●
- Draining wounds ●
- Surgical wounds (donor sites/grafts, post-Mohs' surgery, post-laser surgery, podiatric, wound dehiscence)
COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE VI. PREDICATE DEVICE
The subject MiroTract Wound Matrix has the same intended use and similar technological characteristics as the predicate Miro3D Wound Matrix. Both the MiroTract and Miro3D wound matrices are made from porcine liver that is decellularized using the same perfusion process, materials, and concentrations. For Miro3D, the prepared liver tissue is dried and cut into four defined sizes in cube shape. For MiroTract, the prepared liver tissue is dried and cut into a defined size, threaded and radially compressed onto the guidewire of the MiroTract delivery system to create four MiroTract Wound Matrix sizes (3 and 5 mm Ø each offered in a 5 cm or 9 cm length). The change in wound matrix configuration (dry, uncompressed for Miro3D and dry, compressed onto a guidewire for MiroTract) does not change the principle of operation of the collagen wound matrices for wound management. Both the subject and predicate wound matrices are hydrated with the same hydrating solutions, either before or after wound placement. The MiroTract device includes a delivery system that consists of a nitinol guidewire with stainless steel tip and Pebax tamp tube. An optional Introducer Set accessory that consists of a tearaway sheath and dilator is also provided. MiroTract uses the same tray packaging material and outer foil pouch as Miro3D and is sterilized by the same sterilization method, e-beam
6
irradiation. The MiroTract packaging includes a packaging stopper disc to prevent the tamp tube from sliding off the guidewire when the device is removed from the tray.

VIII. CONCLUSIONS
The subject MiroTract Wound Matrix has the same Intended Use as the predicate Miro3D Wound Matrix for wound management. The differences in technological
9
differences have been demonstrated to not raise different questions of safety and effectiveness. Performance testing provides evidence that the MiroTract Wound Matrix performs as intended and is as safe and effective as the predicate device. Therefore, the subject MiroTract Wound Matrix device is substantially equivalent to the predicate Miro3D Wound Matrix device (K223257).
