Main advantages:

• Handle for oval sheath cup

The core of the sheath could rotate freely and independently during the placement of the sheath, which was advantageous for the development of ureteral stenosis.

• Sheath tube with scale indication

It is convenient to observe the insertion depth of the sheath tube.

• Super smooth hydrophilic coating

The sheath tube and sheath core are covered with hydrophilic coating, which has small friction coefficient and long-lasting hydrophilicity.

• Excellent pushability and flexability

The outer wall of the sheath tube is made of mixed polymer materials and reinforced 304 stainless steel coils to provide better pushing and bending resistance.

• Large outer diameter ratio of sheath

The tube wall is thinner, the outer sheath is thinner under the same inner diameter, and the sheath is more smooth.

• Smooth transition of sheath core

Oblique section design, sheath sheath core close fit, smooth placement.

• Gradient headend design

The design of the head end of the sheath core is 5mm in a straight section, so that the expansion process is more gentle and the damage to the ureter is reduced.
