Traxcess® 7 Mini: Ultra-Fine 0.007 in Guidewire for Extreme Distal Intracranial Navigation Beyond M3/A3

The Traxcess® 7 Mini is an ultra-fine 0.007 in outer-diameter neurovascular microguidewire from MicroVention Terumo, the smallest calibre wire in the Traxcess family and one of the finest neurovascular wires available for clinical use. It is designed for navigation in intracranial vessels that are too small or too spasm-prone for standard 0.014 in wires or even 0.010 in intermediate wires.

The clinical need for sub-0.010 in wires arises in distal AVM embolization targeting feeders from M3, A3, P3, and beyond; treatment of peripheral aneurysms (mycotic/infectious) in distal territory; and selective catheterization for ultra-distal DAVF embolization. In these applications, a 0.014 in wire occupies an unacceptable proportion of the lumen in vessels below 1 mm, creating perforation risk from wall contact force that the 7 Mini eliminates.

0.007 in (0.18 mm) outer diameter, radiopaque platinum-alloy distal tip, hydrophilic coating along the distal working segment. The wire requires ultra-low-profile microcatheters specifically designed for sub-0.010 in wire compatibility — standard Headway 17, 21, and 27 microcatheters are not compatible. Operators must have the appropriate companion microcatheter on the sterile field before attempting 7 Mini navigation.

Working length is appropriate for standard femoral access neurointerventional setups. The very fine diameter means lower column support than larger-gauge wires, and tip reshaping is not recommended after initial shape configuration.

Distal AVM embolization targeting feeders beyond M2/A2, where feeding vessel diameter falls below 1 mm. Treatment of peripheral aneurysms arising from M3 or A3 segments in the context of infective endocarditis or trauma. Selective catheterization for extreme-distal DAVF embolization where the fistulous connection is at a third-order or cortical arterial level. In all these applications, the alternative to the 7 Mini is often open surgery or radiosurgery — the 7 Mini enables a minimally invasive endovascular option where no other wire can safely access the target.

In pediatric patients with small vessel calibres, the 7 Mini may be needed for applications that would use a 0.010 in wire in adult anatomy.

Confirm the companion ultra-low-profile microcatheter is on the sterile field before attempting 7 Mini navigation. Load the wire very gently to avoid kinking — do not use standard torque devices calibrated for 0.014 in wires as they will damage the finer wire body. Advance under high-magnification fluoroscopy with digital subtraction road-map.

Limit torque inputs to very small rotational increments. The force required to injure a sub-millimetre intracranial vessel with a 0.007 in wire is very low. Stop at any resistance and assess fluoroscopically before continuing. Do not push the wire against obstruction.

Modern Medical Solutions is the authorised MicroVention Terumo distributor for Tajikistan and Afghanistan. Traxcess 7 Mini is available on request for centres performing extreme-distal neurointerventional procedures in Tajikistan and Afghanistan. Given its highly specialised indication, it is typically ordered case-by-case with advance notice.
