• 3-stage dilation can be inflated to 3 diameters under different pressure, reducing procedure cost；
Double Dilatation Effect
• Anti-burst balloon protests tissue under high pressure for safer dilation； • Special polymer allows consistent inflation； • Fast inflation and convenient operation；
Excellent Passing performance
• Lubricious sheath provides good steerability with low friction, kink-resistance, flexibility, and ease to push； • Soft-tip design makes it easier to cross through tortuous lumen, reducing risk of tissue damage； • Short withdrawal time；
