Introduction to Disposable PEBAX Balloon Microcatheters and Their Applications in Medical Devices

Introduction to the thin-walled microcatheter structure of PEBAX balloon

Catheter body：PEBAX,Exceptional mechanical properties: By selecting PEBAX segments of varying stiffness, a gradual change in catheter stiffness can be achieved from proximal to distal, ensuring strong proximal support and ultra-flexible distality. This is crucial for navigating tortuous blood vessels.

Tube wall structure：thin-wall design,Increase the inner lumen/decrease the outer diameter: provide a larger instrument channel with the same outer diameter (compatible with thicker coils, stents, etc.), or achieve a smaller outer diameter with the same inner diameter (less trauma, reaching more distal ends).

Core Features and Advantages of the Product

1.Ultimate passability and tracking performance:

PEBAX's progressively stiffer design allows the catheter to follow the guidewire like a "snake," traversing extremely tortuous blood vessel pathways in the brain, heart, and other locations.

The thin-walled design reduces resistance, enabling it to reach more peripheral lesion sites.

2.Excellent resistance to compression and flexural stress:

Despite its thin walls, the high-performance PEBAX material, combined with a sophisticated braided reinforcement layer (usually embedded in the wall), ensures that the lumen does not collapse in tortuous blood vessels, guaranteeing unimpeded device delivery.

3.Precise balloon assist function:

The balloon can be rapidly inflated and deflated with a small volume, providing temporary support during the procedure. The transition between the push rod and the balloon is smooth, minimizing the risk of blood vessel damage.

PEBAX balloon microcatheters are primarily used in delicate interventional procedures that require the highest level of instrumentation.

Neurointervention

• Intracranial aneurysm embolization: The catheter is superselectively placed to the neck of the aneurysm, and the balloon is temporarily inflated to block blood flow ("balloon-assisted embolization"), which makes the coils more stable and densely packed, preventing dislodgement. This is its most classic and core application.

Cardiovascular intervention

• Coronary/peripheral angioplasty: used for pre- or post-dilation of smaller diameter vessels or branch vessels.

Other fields

• Tumor embolization: Superselective delivery to the tumor-feeding artery for chemotherapy drug infusion or release of embolized particles.

• Visceral vascular intervention: used for the creation or embolization of delicate branches such as the renal artery and hepatic artery.
