Benefit
1. Reduces Intra-luminal Pressure
A vortex is created by the continuous irrigation and suction. It reduces the operational (intra-luminal) pressure and reduces the risk of surgery
2. No More Stone Retropulsion
Effectively prevents retrograde stone migration with Negative Pressure Aspiration and at the same time removes the stone fragments.
3. Improved Visual Field
Under the continuous irrigation and suction, bleeding and dust storm from stone pulverization no longer obscure the visual field.
4. Improved Stone Clearance
Stone fragments will aggregate at the distal end of the ClearPetra sheath instead of scattering and are removed through the oblique side port on the ClearPetra Sheath by the continuous suction.
5. No Accessory Device Required
Stone baskets, forceps, and anti-retropulsion devices are no longer necessary. Under the Negative Pressure Aspiration, the stone fragments are evacuated spontaneously
