Neurovascular Intervention Catheter Solutions

Our Neurovascular Intervention Catheter Solutions are developed for demanding neuro intervention applications where precise navigation, stable support, smooth delivery, and reliable distal performance are essential.

Designed for complex and tortuous neurovascular pathways, these catheter solutions can support vascular access, intracranial navigation, device delivery, aspiration support, embolic material delivery, and guidewire support.

The product family can include:

• Neurovascular microcatheter
• Distal access catheter
• Neuro aspiration catheter
• Neuro support catheter
• Neuro long sheath catheter
• Neurovascular guide catheter
• Delivery catheter
• Shaped neurovascular catheter
• Reinforced neurovascular catheter shaft

By combining suitable shaft structures, material combinations, reinforcement designs, distal tip configurations, and coating options, we help customers develop catheter products with a strong balance of flexibility, trackability, pushability, kink resistance, torque response, lumen stability, and distal tip safety.

Our Advantages

1. Application-Focused Neurovascular Development

Neurovascular procedures require catheters that can navigate small, delicate, and highly tortuous vessels while maintaining controlled delivery performance.

• Smooth navigation through tortuous pathways
• Flexible distal section for delicate vessel access
• Stable proximal support for device delivery
• Reliable lumen patency
• Kink resistance during advancement
• Smooth transition between shaft sections
• Atraumatic distal tip performance

2. Balanced Shaft Performance

For neurovascular intervention, catheter shaft design must balance softness and support. A catheter that is too soft may lack pushability, while a catheter that is too stiff may reduce trackability and distal safety.

• Trackability
• Pushability
• Torque response
• Kink resistance
• Flexibility gradient
• Proximal support
• Distal softness
• Lumen stability
• Device compatibility

3. Reinforced Shaft Technology

Many neurovascular catheters require reinforced shaft structures to improve support, torque response, and kink resistance. Structure options can be selected according to the target application and performance requirements.

• Single-layer or multi-layer shaft
• PTFE-lined shaft
• Braided shaft
• Coil-reinforced shaft
• Stainless steel reinforcement
• Nitinol reinforcement
• Variable stiffness shaft
• Flexible distal section
• Reinforced proximal section

4. Distal Tip & Transition Design

The distal section is critical for neurovascular catheter performance. A smooth and controlled distal design helps improve navigation, reduce trauma risk, and support precise device delivery.

• Soft distal tip
• Atraumatic tip
• Tapered tip
• Shaped tip
• Radiopaque tip
• Multi-durometer distal segment
• Smooth shaft-to-tip transition
• Customized curve configuration
