NEUROvascular NAVigation With Remotely Controlled Deflectable Guidewire, Study I (NeuroNAV Study I)

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.

Treatment and study plan

SmartGUIDE (deflectable guidewire)

Device

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.

Any standard of care guidewire

Device

The control device is any standard of care guidewire as per hospital routine indicated for neuro-interventional procedures.

Primary outcomes

  1. Performance

    Time frame: 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 outcomes

  1. Usability

    Time frame: During index procedure

    Usability data (shape retention, pushability, trackability, navigability, support, proximal access complexity) collected through questionnaire.

  2. Procedural times

    Time frame: During index procedure

    Procedural times (duration of tip reshaping, duration of access to target, duration of fluoroscopic exposition).

  3. Intra-procedural adverse events

    Time frame: During index procedure and up to 48 hours post procedure

    Occurrence of adverse events.

  4. Intra-procedural device deficiencies

    Time frame: During index procedure

    Occurrence of intra-procedural device deficiencies.
