The original and patented system for continuous flow lithotripsy for effective and efficient treatment of kidney stones, using negative pressure aspiration through an oblique side port. ClearPetra maintains a clear operative field throughout the procedure; high stone clearance rate; reduces intra-luminal pressure; prevents stone repulsion; removes the need for other tools; reduces operating time.
The flexible tip can be passively deflected 180deg to the lower pole calyces by the flexible ureteroscope, allowing for efficient and effective treatment of urinary stones.
