Construction and application

Surface
Hydrophilic coating

Lowers insertion resistance and the risk of ureteral injury. The coated section can be specified.

Construction
304SS reinforced, three layers

A 0.08 × 0.3 mm stainless flat wire in the middle layer keeps the lumen from collapsing under negative pressure.

Application
PCNL · flexible ureteroscopy

Used in percutaneous nephrolithotomy and flexible ureteroscopic lithotripsy. Accessory configuration follows your requested specification.

Frequently asked

FAQ
What is the difference between Flexible and Inflexible?

Path conformability versus support. For tortuous paths we suggest Flexible; where straight-line support is needed, Inflexible.

Is the suction unit supplied with it?

We supply the sheath and its accessories; the suction unit is separate. Tell us the connection standard and we build to it.

Can I get 350 mm?

A 350 mm working length is in the catalogue. Ask us with your quantity and we confirm.

Can it be supplied sterile?

We handle EO sterilization and individual packaging, on a single-use basis.
