QuadraSphere ® microspheres (only the United States)

A predictable flow guide targeted

QuadraSphere ® microspheres after calibration, with hydrophilic, compressible is as high as 80%, so as to promote micro catheter smooth conveying.Once through the catheter, they will rebound to the provisions of the ball, and with a consistent cross sectional diameter, to achieve a predictable, blood flow guide targeted.

Targeted shade

Different sizes of * QuadraSphere microspheres occluded arteries in the body between the values with different diameter, can provide targeted occlusion.

QuadraSphere Q2 microspheres shows (including 78 m in value, compared with the larger QuadraSphere statistically significant differences.

* for the Merit that dominate the pork liver embolism model research.QuadraSphere microspheres in 50/50 of the brine/contrast agent mixture preparation.

Highly vascularized tumor embolism of before and after embolization angiogram showed QuadraSphere microspheres on targeted embolism.

Experience the power of consistency

Soft and easy to fit a essel QuadraSphere microspheres in order to realize the complete occlusion:

• Reduce the risk of recanalization¹
• Make larger tumor necrosis^{2, 3}
• In the vessel wall and provide the best contact between microsphere surface^{1, 4}
• To strengthen therapeutic effect and reduce to embolism quantity of products required for the end¹

recognized

QuadraSphere microspheres is an accepted targeting liver embolization platform.Suitable for: QuadraSphere microspheres

• Cancer of the liver
• Arteriovenous malformation (AVM)
• High vascular tumor (HVT)

Super absorbent polymer

Called QuadraSphere microspheres, super absorbent polymer (SAP) microspheres using dry packaging, but once in contact with water medium, they will swell to a product about four times as much as marked on the label size.
