No
The device description and performance studies focus on the material properties and biological compatibility of bovine pericardium, with no mention of software, algorithms, or data processing that would indicate AI/ML.

Yes
The devices are intended for various forms of repair and reconstruction of body tissues and structures, indicating a therapeutic purpose to treat or alleviate a condition.

No

The devices described (CV Peri-Guard, Vascu-Guard, Supple Peri-Guard) are intended for use as patch materials and prostheses for surgical repair of various defects and tissues. Their intended use is to physically repair or replace structures, not to diagnose conditions.

No

The device description explicitly states it is prepared from bovine pericardium, which is a biological material, not software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended uses described are for surgical repair and reconstruction of various tissues and structures within the body (intracardiac defects, blood vessels, hernias, etc.). This is a therapeutic or reconstructive purpose, not for diagnosing a condition based on in vitro analysis of samples.
  • Device Description: The device is described as a patch material prepared from bovine pericardium. This is a biological material intended for implantation or surgical use, not for performing tests on biological samples outside the body.
  • Lack of IVD Characteristics: The description does not mention any components or processes typically associated with IVDs, such as reagents, calibrators, controls, or methods for analyzing biological samples (blood, urine, tissue, etc.).
  • Performance Studies: The performance studies described focus on the physical properties and biocompatibility of the material, which are relevant for an implantable or surgical device, not an IVD.

In summary, the device's function is to physically repair or reinforce tissues within the body, which is the definition of a medical device used in vivo, not an in vitro diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Cross-linked pericardium was treated with 1 molar sodium hydroxide (1M NaOH) for 60-75 minutes at 20 -25 C, rinsed with deionized (DI) water and neutralized with citrate solution, followed by a final DI water rinse. Sodium hydroxide treated and control (non-NaOH-treated) samples were subjected to shrink, suture, and thickness testing. Results showed no significant difference between the test and control samples. The test and control samples were subjected to bioburden, sterility, pH, pyrogen, and chemical resting. Results showed no significant difference between the test and control samples. Samples of the NaOH-treated pericardium were also subjected to biocompatibility and animal testing. Results showed that the 1M NaOH treatment did not produce significant differences in biocompatibility or inflammation when comparing the treated versus non-treated pericardium.
