No
The summary describes image registration and overlay techniques, which are standard image processing methods and do not inherently require AI/ML. There is no mention of AI, ML, or related terms like deep learning or neural networks in the document. The performance studies focus on registration accuracy and measurement, not on AI/ML model performance metrics.
No
The device provides image guidance to assist in positioning endovascular devices and does not directly provide therapy.
No
The device is described as an image guidance system that overlays pre-operative 3D vessel anatomy onto live fluoroscopic images to assist in positioning endovascular devices. Its intended use explicitly states it is "to assist in the positioning," and it "provides navigation tools." It does not provide a diagnosis or aid in diagnosing a condition.
Yes
The device description explicitly states that EndoNaut is a "stand-alone software medical device" and will be marketed as a "software only solution." While it interacts with external hardware (Windows computer, X-ray machine video port), the device itself, as described and marketed, is solely the software component.
Based on the provided information, this device is NOT an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- EndoNaut's Function: EndoNaut's intended use is to provide image guidance during endovascular procedures by overlaying pre-operative imaging onto live fluoroscopy. It assists in the positioning of medical devices within the body.
- No Specimen Analysis: The device does not analyze any biological specimens taken from the patient. Its function is purely based on processing and displaying medical images.
Therefore, EndoNaut falls under the category of a medical device used for image guidance and surgical assistance, not an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
EndoNaut provides image guidance by overlaying preoperative 3D vessel anatomy onto live fluoroscopic images in order to assist in the positioning of the guidewires, catheters and other endovascular devices.
EndoNaut is intended to assist endovascular procedures in the thorax, abdomen, neck, pelvis and lower limbs. Suitable procedures include (but not limited to) endovascular aortic aneurysm repair (AAA and TAA), angioplasty, stenting and embolization in iliac arteries and corresponding veins.
EndoNaut is not intended for use in the X-ray guided procedures in the liver, kidneys or pelvic organs.
