Y-type Ureteral Access Sheath
Designed for the effective and efficient treatment of urinary stones using negative pressure
aspiration through an oblique side port.
It has high stone clearance rate, reduces the intra-luminal pressure in the urinary tract, prevents
stone retropulsion, improves visual field, obviates the need of stone baskets, forceps, or any
anti-retropulsion devices, and saves operating time. Under the Negative Pressure Aspiration, the
stone fragments are evacuated spontaneously.
