No
The device description and performance studies focus on the physical and mechanical properties of a catheter, with no mention of AI or ML capabilities. The "Mentions AI, DNN, or ML" section explicitly states "Not Found".
No
The device is described as a catheter for "introduction of interventional devices" and "facilitating the insertion and guidance of appropriately sized interventional devices," indicating it is an accessory device rather than a therapeutic one itself. Its purpose is to aid in delivering other devices that might be therapeutic.
No
The device is described as a catheter for the introduction and guidance of interventional devices, not for diagnosing conditions. Its primary function is to facilitate procedures, not to provide diagnostic information.
No
The device description clearly details physical components such as a catheter, hydrophilic coating, radiopaque marker, luer hub, and bovine derived tallow, indicating it is a hardware device.
Based on the provided information, the AXS Lift Intracranial Base Catheter is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use is "introduction of interventional devices into the peripheral and neurovasculature." This describes a device used within the body for a procedural purpose, not for examining specimens outside the body to diagnose a condition.
- Device Description: The description details a catheter designed for facilitating the insertion and guidance of other devices within blood vessels. This is consistent with an interventional medical device, not an IVD.
- Lack of IVD Characteristics: There is no mention of the device being used to test or analyze biological samples (blood, urine, tissue, etc.) or to provide diagnostic information based on such analysis.
IVD devices are specifically designed to be used in vitro (outside the living body) for the examination of specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. The AXS Lift clearly operates in vivo (within the living body).
