The proposed device is substantially equivalent to the predicate device Dura-Matrix (K061487) in intended use, design and function. The proposed device is similar in design, function, materials and processing to reference devices Tutopatch™ bovine pericardium (K991296, K073097, K081538 and K091142) and similar to intended use, function, design and processing to reference device Tutoplast® Dura Mater (K910555). ## Device Description: The proposed device is composed of bovine pericardium processed through a proprietary tissue preservation and sterilization process which includes gamma irradiation. The proposed device is composed of collagenous connective tissue with three-dimensional intertwined fibers and can be fixed regardless of the direction of the device. Collagenous connective tissue with multidirectional fibers retains the mechanical strength and elasticity of the native tissue, while providing the basic structure to support replacement by new endogenous tissue. The proposed device in its unopened, undamaged package is sterile. ## Indications for Use: The device is indicated as a dura substitute for the repair of dura mater. {1}------------------------------------------------ # Summary of Technological Characteristics Summary of Tachnological Characteristics: The device is composed of non-crosslinked bovine pericardium that has ben material, design del production as listed in the blo belo | Characteristic | Proposed Device | Predicate Device,<br>Dura-Guard<br>(K950956 and<br>K982282) | Predicate Device,<br>DuraMatrix<br>(K061487) | Predicate Device,<br>Lyoplant<br>(K970851) | Reference Device,<br>Tutopatch<br>(K991296,<br>K081538, K091142) | Reference Device,<br>Tutodent<br>(K073097) | Reference Device,<br>Tutoplast<br>processed human<br>dura<br>mater(K910555) | |-------------------------|-----------------------------------------------------|-------------------------------------------------------------|----------------------------------------------|--------------------------------------------|------------------------------------------------------------------|--------------------------------------------|-----------------------------------------------------------------------------| | Intended Use | Dura substitute | SAME | SAME | SAME | Surgical mesh | Barrier, Animal<br>Source, Intraoral | SAME | | Material | Bovine pericardium | SAME | Bovine collagen | Collagen from<br>bovine pericardium | SAME | SAME | Human dura | | Design | Terminally sterilized<br>sheets in various<br>sizes | Aseptically<br>processed sheets<br>in various sizes | Resorbable,<br>suturable<br>membrane | Absorbable,<br>suturable<br>membrane | SAME | SAME | SAME | | Function | Dura substitute | SAME | SAME | SAME | Scaffold for soft<br>tissue repair | Scaffold for soft<br>tissue repair | SAME | | Processing | Proprietary tissue<br>sterilization process | Apex processing | Proprietary<br>processing | Proprietary<br>processing | SAME | SAME | SAME | | Chemical<br>composition | | | | | | | Not applicable to these devices | | Energy Source | | | | | | | Not applicable to these devices | ਟ {2}------------------------------------------------ ## Performance Data Supporting Substantial Equivalence Determination: The proposed device is equivalent to the predicate devices in intended use, material, design, and function. The biomechanical properties of the proposed and predicate devices were evaluated in a series of in vitro tests and implantation in an animal model. Burst strength, uniaxial strength and suture pullout strength were substantially equivalent for the proposed and predicate devices. The table below summarizes the testing used to determine substantial equivalence of the proposed device. | Test | Results | Conclusions | |---------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------|-----------------------------| | Cytotoxicity - Inhibition<br>of Cell Growth Assay | No leachable materials were released in cytotoxic<br>concentrations from the device. The proposed device is<br>non-cytotoxic. | Substantially<br>equivalent | | Suture Pull out (N) | The proposed device suture pull-out max load is comparable<br>to the DuraMatrix predicate device. | Substantially<br>equivalent | | Burst Strength (N) | The proposed device burst strength is greater than the<br>DuraMatrix predicate device. | Substantially<br>equivalent | | Shrink temperature (°C) | The shrink temperature of the proposed device is<br>comparable to the Lyoplant predicate device. | Substantially<br>equivalent | | Max Load (N) | The maximum load at failure of the proposed device is<br>comparable to the DuraMatrix predicate device. | Substantially<br>equivalent | Pyrogenicity of the device was evaluated using the Limulus Amoebocyte Lysate (LAL) assay on the final sterilized device. The device did not elicit a response. All device lots will be tested to ensure the endotoxin level is <2.15 EU per device. The functional properties of the proposed and predicate device were evaluated in a pre-clinical implantation study and the proposed device performed as well as a similar dura substitute. Clinical and gross pathology, cerebrospinal fluid leakage and the local effects of implantation were assessed and results demonstrate the proposed and predicate devices are substantially equivalent. The proposed device was increasingly resorbed. At the end time point the proposed device demonstrated moderate resorption and marked integration. Clinical evaluation of the proposed device confirms the clinical substantial equivalence to the predicate devices. Sabatino et. al. (2014)1 present the results of a prospective cohort study which compared the clinical outcomes from duraplasty using autologous galea-pericranium and Tutopatch (the proposed device as marketed in the European market). The study evaluated postoperative results (with a minimum follow-up of 12 months), ease of use and procedure costs. The proposed device performed adequately with no evidence of adverse health effects. Filipi et. al. (2000)² present a retrospective evaluation that summarized the outcomes for 32 patients who received Tutoplast bovine pericardium dural grafts (proposed device as marketed in ex-US countries) as part of a variety of neurosurgical procedures. The proposed device was easily sutured with standard suture material and formed a watertight seal. The proposed device provided "excellent material implantation characteristics and favorable clinical outcome" and is recommended as a safe and suitable material for duraplasty. Filipi et. al. concluded, "these results confirm the excellent suitability of Tutoplast bovine pericardium for dural substitution". Results from in vitro, animal studies and clinical evaluation demonstrate that the proposed device is substantially equivalent to the predicate devices for use as a dura substitute.
