Brain vascular model SJ001D-A

cerebralintracranialfemoral artery

Product overview
The SJ001D-A neurovascular simulation model reproduces cerebral and aortic vascular anatomy from the femoral artery up to the A2 segment of the anterior cerebral artery and the M2 segment of the middle cerebral artery. It includes a complete circle of Willis and five intracranial aneurysms of different sizes. The model is produced at 1:1 scale from reconstructed human CT data and 3D printed, then cast in silicone (shore 40A) for realistic handling. Modular construction allows connection/disconnection of intracranial, aorta and abdominal sections using custom connectors.

Application

• Simulation of aneurysm packing, embolization and cerebral angiography procedures.
• Development, bench testing and verification of neurovascular devices (catheters, stents, balloons, guidewires, microcatheters).
• Hands‑on training for endovascular neurointerventions, device demonstrations and education.
• Quantitative perfusion and imaging analysis (CTA, DSA, MRA, PIV, Doppler sonography).

Custom Service Options

• Custom number, size and location of intracranial aneurysms.
• Addition of stenotic lesions, arteriovenous fistulas, emboli or other intracranial pathologies.
• Bilateral radial artery access configuration; lesions can be added to carotid arteries.
• Aortic arch customization: Type I, II, III or variants.
• Additional complex structures can be integrated into the abdominal section.
• Optional 3D visualization by fixing the model inside a transparent acrylic box.
• Custom builds based on customer CAD/STL/STP/STEP files.
