Unruptured Cerebral Aneurysm
Conditions
Brief summary
The aim of the study is to confirm the safe and successful use of the SmartGUIDE guidewire, when used in neuro interventions. The performance of the SmartGUIDE guidewire in terms of safe and successful navigation within the neurovasculature will be compared to standard of care guidewire on the market.
Interventions
SmartGUIDE is a deflectable guidewire for use in interventional procedures in the neurovasculature and the peripheral vasculature. It can be used to selectively introduce and position catheters and other interventional devices within the peripheral and neurovasculature. The device is a steerable guidewire with a deflectable tip. This allows adjusting the shape of the tip, dynamically, while the physician navigates the device in the patient's arterial and venous circulatory system.
The control device is any standard of care guidewire as per hospital routine indicated for neuro-interventional procedures.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Performance | During index procedure | Intra-procedural technical success defined as successful navigation of device to the target vessel without need for shaping by hand, removal or exchange. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Usability | During index procedure | Usability data (shape retention, pushability, trackability, navigability, support, proximal access complexity) collected through questionnaire. |
| Procedural times | During index procedure | Procedural times (duration of tip reshaping, duration of access to target, duration of fluoroscopic exposition). |
| Intra-procedural adverse events | During index procedure and up to 48 hours post procedure | Occurrence of adverse events. |
| Intra-procedural device deficiencies | During index procedure | Occurrence of intra-procedural device deficiencies. |
