Stability & Flexibility

Reinforced Structural Technology

The Bi-Flex Evo™ sheath is constructed with a PEBAX® outer layer, a steel spring coil layout, and a PTFE inner lining. This composition provides high strength and stability, ensuring excellent resistance to kinking and allowing for easy entry and withdrawal of the endoscope.

Optimized Entry

Atraumatic Dilator Transition & Coating

The transition zone between the dilator and the sheath tip is engineered to facilitate easy passage. An active Hydromer® Hydrophilic Coating decreases friction significantly.

Additionally, a distal platinum ring allows for fluoroscopic visualization of the tip, and a graduated inner part measures ureter dilation depth.
