The summary describes an automated function using a peristaltic pump and a built-in alarm system, but there is no mention of AI, ML, or any learning or adaptive capabilities. The "automatic operation" appears to be a pre-programmed function, not one driven by AI/ML.
Yes
The device is intended for "temporary occlusion of large vessels and blood pressure monitoring including patients requiring emergency control of hemorrhage," which are therapeutic interventions. Additionally, it is an "occlusion balloon catheter," and its stated purpose is to "control of hemorrhage," all indicative of a therapeutic device.
No
The device is described as an "occlusion balloon catheter" intended for "temporary occlusion of large vessels and blood pressure monitoring including patients requiring emergency control of hemorrhage." While it monitors blood pressure and pressure at the catheter tip, its primary function is therapeutic (occlusion), not diagnostic interpretation of patient conditions.
No
The device description clearly outlines hardware components, specifically a catheter and an assistant hub, and details physical interactions like Luer lock ports and a peristaltic pump. The performance studies also include extensive testing of physical characteristics and in vivo performance, indicating it is not solely software.
Based on the provided information, the Neurescue device is not an In Vitro Diagnostic (IVD).
Here's why:
- Intended Use: The intended use is for "temporary occlusion of large vessels and blood pressure monitoring including patients requiring emergency control of hemorrhage." This describes a device used within the body (in vivo) for a therapeutic and monitoring purpose.
- Device Description: The description details a catheter with an occlusion balloon and a system for inflation/deflation and pressure monitoring. This is consistent with an in vivo medical device.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or compatibility testing.
IVDs are devices used outside the body to examine specimens. The Neurescue device is clearly designed for use inside the body.

Device Description
The NEURESCUE device is a large vessel occlusion catheter comprised of two main components: The NEURESCUE Catheter and the NEURESCUE Assistant.
The Catheter is an occlusion balloon catheter and the Assistant is a hub for interfacing with the operation of the Catheter. During normal use the device can be operated automatically. Alternatively, the device can be operated manually.
For manual use the interface consists of two Luer lock ports for:
- Manual inflation and deflation of the balloon with saline -
- -Flushing of the arterial FLUSH port with saline
Inflation and deflation of the balloon can be accomplished by an automatic filling and deflation function (automatic operation with a peristaltic pump) or manually.
Whether the filling is performed manually or automatically, the user is informed of the pressure at the tip of the Catheter. The device has a built-in alarms system.
