The device description clearly states it is an "implantable, animal-sourced, acellular surgical mesh" and describes its physical properties and use in surgery, indicating it is a physical medical device, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the "management and protection of tendon injuries." This is a therapeutic and structural purpose, not a diagnostic one.
- Device Description: The device is an "implantable, animal-sourced, acellular surgical mesh." It's designed to provide a scaffold for tissue repair and act as an interface. This is a physical, structural function within the body.
- IVD Definition: In Vitro Diagnostics are devices used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening. This device does not perform any such examination of specimens.
The device is a surgical implant used directly in the body for tissue support and repair, which falls outside the scope of In Vitro Diagnostics.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Bench and animal data show that the subject Miromatrix Biological Mesh TW is substantially equivalent to the predicate Integra Tendon Wrap™ Tendon Protector with regard to performance. Specifically:
- The total tensile strength and suture pullout strength were evaluated and measured for both the Miromatrix Biological Mesh TW and the predicate device. The Miromatrix Biological Mesh TW was shown to have higher tensile and suture pullout strength than the predicate device. These differences do not have any impact on safety and effectiveness, and therefore, on substantial equivalence.
- Animal testing comparing the subject and predicate devices in a 4 and 10-week partial Achilles tendon defect model was performed. After 4 and 10 weeks, the average tissue attachment was comparable. The healing response at 4 and 10 weeks was also comparable.

DEVICE DESCRIPTION 4.
The Miromatrix Biological Mesh TW is an implantable, animal-sourced, acellular surgical mesh that is derived from porcine liver tissue. The liver tissue undergoes perfusion decellularization and the resulting mesh is comprised primarily of collagen type I. The Miromatrix Biological Mesh TW provides a scaffold during tissue repair and is designed to be an interface between the tendon and tendon sheath or the surrounding tissues. The Miromatrix Biological Mesh TW is designed for placement under, around or over the injured tendon. The device is terminally sterilized by electron beam irradiation in its packaging and is hydrated, moist and flexible when its packaging is opened. The mesh is available in sizes ranging from 1 cm x 2 cm to 10 cm x 20 cm, and may be trimmed or cut as required before being sutured to the surgical site.
5. INDICATION FOR USE
The Miromatrix Biological Mesh TW is indicated for the management and protection of tendon injuries in which there has been no substantial loss of tendon tissue.
4
This indication for use is identical to that of the predicate device, the Integra Tendon Wrap™ Tendon Protector (K053655).
COMPARISON OF TECHNOLOGICAL CHARACTERISTICS 6.
The similarities and differences in technological characteristics between the subject Miromatrix Biological Mesh TW and the predicate mesh are summarized below.
Similarities 6.1.
The Miromatrix Biological Mesh TW is similar in design to the predicate Integra Tendon Wrap™ Tendon Protector (K053655). Both are designed to provide a protective environment while the tendon is healing for the management and protection of the tendon injuries in which there has been no substantial loss of tendon tissue.
In addition, the Miromatrix Biological Mesh TW is identical in materials (i.e., porcine liver tissue) to the reference device, the Miromatrix Biological Mesh (K134033).
6.2. Differences
Although similar in design, there are minor differences in dimensions between the subject Miromatrix Biological Mesh TW and the predicate Integra Tendon Wrap™ Tendon Protector (K053655). The Miromatrix Biological Mesh TW has a thickness of 0.1-1.5 mm and sizes from 1x2 cm to 10x20 cm. Based on Miromatrix's own measurements, the predicate Integra Tendon Wrap™ Tendon Protector has a thickness range that slightly exceeds that of the subject device. Based on publically available information, the sizes of the predicate are similar, i.e., 5x5cm and 10x12.5cm.
When compared to the reference device (i.e., the Miromatrix Biological Mesh of K134033), the only difference in design are a slight change in dimensions, i.e., a reduction in the mesh thickness (i.e., from 0.5-3 mm to 0.1-1.5 mm) and a reduction in the maximum mesh size (i.e., from 20x30 cm to 10x20 cm).
In terms of materials, the predicate Integra Tendon Wrap™ Tendon Protector is comprised of a porous matrix of cross-linked bovine Type I collagen and glycosanminoglycan (GAG). While the predicate material is different from the porcine liver tissue that comprises the subject device, the difference does not raise a new question of safety and effectiveness.
The subject device has the same material as the reference device (K134033). Thus, the biocompatibility of the subject device material (i.e., porcine liver) and, therefore, its safety for the proposed intended use has already been established as part of K134033.
7. PERFORMANCE DATA
Because the materials of the subject Miromatrix Biological Mesh TW are identical to that of the reference device, the Miromatrix Biological Mesh (K134033), no new biocompatibility testing is required to demonstrate substantial equivalence.
Shelf life testing was performed to establish the proposed shelf life of the device.
5
Bench and animal data show that the subject Miromatrix Biological Mesh TW is substantially equivalent to the predicate Integra Tendon Wrap™ Tendon Protector with regard to performance. Specifically:
- . The total tensile strength and suture pullout strength were evaluated and measured for both the Miromatrix Biological Mesh TW and the predicate device. The Miromatrix Biological Mesh TW was shown to have higher tensile and suture pullout strength than the predicate device. These differences do not have any impact on safety and effectiveness, and therefore, on substantial equivalence.
- . Animal testing comparing the subject and predicate devices in a 4 and 10-week partial Achilles tendon defect model was performed. After 4 and 10 weeks, the average tissue attachment was comparable. The healing response at 4 and 10 weeks was also comparable.
8. CONCLUSIONS
The Miromatrix Biological Mesh TW is identical in indications to the predicate Integra Tendon Wrap (K053655).
The Miromatrix Biological Mesh TW is similar in design to the predicate Integra Tendon Wrap (K053655). In terms of materials, the Integra Tendon Wrap is comprised of a porous matrix of cross-linked bovine Type I collagen and glycosanminoglycan (GAG). While the Integra Tendon Wrap material is different from the porcine liver tissue that compromises the subject device, the difference does not raise a new question of safety and effectiveness. The biocompatibility of the subject device material (i.e., porcine liver) has already been established as part of K134033.
Performance testing (bench and animal testing) of the subject device versus the predicate device was performed and the results demonstrate that the subject device is substantially equivalent to the predicate device for the proposed indication for use.
In conclusion, based on the exact same indication for use and comparable design and performance to the predicate Integra Tendon Wrap (K053655) and based on the same materials and comparable design to the reference device Miromatrix Biological Mesh (K134033), as well as favorable preclinical testing, the subject Miromatrix Biological Mesh TW may be found substantially equivalent.
