Disposable Sterile Controlled Catheter

One catheter a month. One touch to control.

A balloon-free indwelling urethral catheter with an integrated ball-bead valve. The patient or carer opens the valve to drain the bladder and closes it again afterwards, without an inflation channel or a drainage bag.

01
Balloon-free quatrefoil tip
A four-lobed tip sits at the bladder neck and keeps the catheter in place without an inflatable balloon.
02
Ball-bead valve
A PTFE ball bead seals the lumen. Moved into the bulged section of the shaft, it opens the outflow; moved back, it closes it.
03
One-touch control
The valve is operated by squeezing the outer end of the catheter. No bag, clamp or inflation syringe is needed between voids.
IndicationFor female patients with voiding dysfunction. Not indicated for male patients. Registered in China only.
