The device is provided sterile and intended for one-time use. ## Device Story Biodesign Onlay Dural Graft is a bioabsorbable, extracellular collagen matrix derived from porcine small intestinal submucosa (SIS). Implanted as a scaffold for dural repair, it facilitates infiltration by patient cells and remodeling into native tissue. Supplied in a lyophilized, sterile state, it can be placed without sutures during skull base dural repair. Used by neurosurgeons in clinical settings, the device serves as a physical barrier to replace or augment the dura mater, promoting healing and reducing potential for cerebrospinal fluid leaks. ## Clinical Evidence No clinical data provided in the document; evidence consists of bench testing, biocompatibility testing, and an animal study. Bench testing confirmed mechanical performance (suture retention, tensile, and burst strength) similar to predicates. Biocompatibility testing (genotoxicity, cytotoxicity, sensitization, systemic toxicity, etc.) on identical material (SurgiSIS Mesh) met ISO 10993-1 standards. Animal study in a rat model demonstrated adequate performance with no adverse physiological or histological effects. ## Technological Characteristics Material: Porcine small intestinal submucosa (SIS) containing Types I, III, IV, and VI collagen. Form factor: Lyophilized matrix, 154 µm to 680 µm thickness. Sterilization: Terminally sterilized. Biocompatibility: Tested per ISO 10993-1. Mechanical properties: Suture retention, ultimate tensile strength, and burst strength. ## Regulatory Identification A dura substitute is a sheet or material that is used to repair the dura mater (the membrane surrounding the brain). ## Predicate Devices - Durasis Dural Substitute ([K031850](/device/K031850.md)) - DuraGen II Dural Regeneration Matrix ([K043427](/device/K043427.md)) ## Reference Devices - SurgiSIS Mesh ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Guinn DEVICE NAME AND CLASSIFICATION Trade/Proprietary Name: Common Name: Classification Regulations: Biodesign Onlay Dural Graft Dura Substitute Class II, 21 CFR §882.5910 (84GXQ) INDICATIONS FOR USE: The Biodesign Onlay Dural Graft is intended for use as a dura substitute for the repair of dura mater. The device is provided sterile and intended for one-time use. #### DEVICE DESCRIPTION: The Biodesign Onlay Dural Graft is composed of a bioabsorbable, extracellular collagen matrix (Small Intestinal Submucosa, SIS). The SIS material that comprises the Biodesign Onlay Dural Graft is identical in composition and technology to that of its predicate Durasis Dural Substitute (K031850), also manufactured by Cook Biotech Incorporated and similar to its other predicate, DuraGen II Dural Regeneration Matrix (K043427) manufactured by Integra LifeSciences. The Biodesign Onlay Dural Graft is implanted as a dura substitute providing a scaffold which becomes infiltrated by the patient's cells and is remodeled into native tissue. The device is packaged in a lyophilized (dried) state and supplied sterile in a sealed double pouch system. The Biodesign Onlay Dural Graft can be placed without sutures during skull base dural repair. #### EQUIVALENCE TO MARKETED DEVICES The Biodesign Onlay Dural Graft is similar with respect to intended use, and identical with respect to materials and technological characteristics to the predicate devices in terms of section 510(k) substantial equivalence, as shown through bench (ultimate {1}------------------------------------------------ 510(k) Premarket Notification: Biodesign® Dural Graft tensile strength, thickness, burst strength), animal (where the device was implanted as an onlay in a rat study), and biocompatibility testing (genotoxicity, direct contact in vitro hemolysis, cytotoxicity, muscle implantation, acute intracutaneous reactivity, sensitization, acute systemic toxicity, pyrogenicity, LAL endotoxins, subchronic systemic toxicity), and clinical studies using the device in cranial base dural repair. #### Bench testing The following mechanical tests were performed on finished, terminally sterilized devices: - . Suture retention strength - Ultimate tensile strength . - Burst strength test . The tests provided evidence that the Biodesign Onlay Dural Graft performed similarly to its predicate devices. #### Biocompatibility testing The following biocompatibility tests were performed on sterilized SurgiSIS Mesh, which is identical in composition to the Biodesign Onlay Dural Graft (according to the ISO 10993-1 standard): - Genotoxicity � - Direct contact in vitro hemolysis � - Cytotoxicity . - Muscle implantation . - Acute intracutaneous reactivity . - ISO Sensitization . - Acute systemic toxicity . - Pyrogenicity . - LAL endotoxins . - Subchronic systemic toxicity . The results of these tests provided evidence that the Biodesign Onlay Dural Graft meets biocompatibility requirements of the ISO standard. #### Animal Study An animal study using finished devices in a rat model where the device was implanted using an onlay technique showed that the device performed adequately with no physiological, histological or functional evidence of adverse health effects were observed. {2}------------------------------------------------ ・ | Device | Biodesign® Onlay
