SUPPLE PERI-GUARD is intended for use as a prosthesis for pericardial closure.

PERI-GUARD is intended for repair of pericardial structures. PERI-GUARD is also intended for use as a patch for intracardiac defects, great vessel, septal defects and annulus repair, and suture-line buttressing.

SUPPLE PERI-GUARD is prepared from bovine pericardium which is cross-linked with glutaraldehyde. SUPPLE PERI-GUARD has been treated with 1 molar sodium hydroxide for 60-75 minutes at 20-25°C. SUPPLE PERI-GUARD is terminally sterilized using gamma irradiation.

SUPPLE PERI-GUARD is packaged between two pieces of foam within a double sterile barrier pouch system. The contents of the unopened, undamaged package are sterile.

The provided document is a 510(k) premarket notification for two devices: SUPPLE PERI-GUARD Pericardium Patch and PERI-GUARD Repair Patch. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than proving that the device meets specific acceptance criteria through a comparative effectiveness study with human readers or presenting detailed performance metrics.

Therefore, the document does not contain the information requested regarding acceptance criteria and a study that proves the device meets those criteria in the context of AI or advanced clinical performance studies.

Specifically, the document does not include:

• A table of acceptance criteria and reported device performance in the format requested (likely due to the nature of a 510(k) submission not requiring explicit performance metrics in this way for equivalence).
• Any details about sample sizes used for a test set, data provenance, ground truth establishment, or expert involvement as typically found in studies for AI/diagnostic devices.
• Information on adjudication methods.
• A multi-reader multi-case (MRMC) comparative effectiveness study with effect sizes for human reader improvement with AI.
• A standalone (algorithm only) performance study.
• Sample sizes or ground truth establishment for a training set (as this is not an AI/machine learning device).

Instead, the document focuses on non-clinical testing to demonstrate safety and performance for substantial equivalence. The studies mentioned are:

1. Bench testing: Assessed aspects like suture retention, thickness, burst strength, ultimate tensile strength, collagenase digestion, chemical residuals, pyrogenicity/LAL, sterilization validation, and packaging/shelf-life. The document states, "Bench testing results support the performance requirements."
2. Biocompatibility testing: Performed in accordance with ISO 10993-1: 2009.
3. Animal studies: Conducted to support safety and efficacy.

These studies are conducted to show the new device is "substantially equivalent" to predicate devices, mainly due to changes in packaging and sterilization methods. The document repeatedly states that the devices (SUPPLE PERI-GUARD and PERI-GUARD) are acting as their own predicates.
