No
The device description and performance studies focus on the material properties and biological performance of a collagen membrane, with no mention of software, algorithms, or data processing that would indicate AI/ML.
No
The device is described as a "dura substitute for the repair of dura mater," which indicates it is a medical implant used for structural repair, not a device that provides therapeutic treatment.
No
Explanation: The device is described as a "dura substitute for the repair of dura mater", which is a therapeutic function, not a diagnostic one. It is a membrane matrix for surgical repair.
No
The device description clearly states it is a "membrane matrix consisting of highly purified collagen derived from bovine dermis," indicating it is a physical, implantable material, not software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "as a dura substitute for the repair of dura mater." This describes a device that is implanted or used directly on the patient's tissue (dura mater) during a surgical procedure.
- Device Description: The description details a physical membrane matrix made of collagen, designed to be sutured in place. This is a physical implantable material.
- Lack of In Vitro Testing: While the performance studies include "in vitro characterization studies," these are tests on the device itself (dimensions, strength, etc.), not tests performed on patient samples (like blood, urine, or tissue) to diagnose a condition or monitor a patient's health.
- Anatomical Site: The anatomical site is the "dura mater," which is a tissue within the body. IVDs typically interact with biological samples taken from the body.
An In Vitro Diagnostic device is specifically designed to be used outside the body (in vitro) to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for the diagnosis, monitoring, or treatment of a disease or condition. This device does not fit that description.
