Advanced Features of ClearPetra

Clearpetra, developed by Wellead Medical, introduces an innovative approach to continuous flow lithotripsy. This state-of-the-art system incorporates Negative Pressure Aspiration, utilizing an oblique side port on the ClearPetra sheath to provide exceptional results.

Reduced Intra-luminal Pressure

The revolutionary ClearPetra System creates a vortex through continuous irrigation and suction, reducing the operational pressure within the urinary tract. This reduction in intra-luminal pressure minimizes the surgical risks associated with urinary stone treatment, enhancing patient safety and ensuring optimal outcomes.

Preventing Stone Retropulsion

Wellead Medical clearpetra effectively prevents retrograde stone migration through Negative Pressure Aspiration while simultaneously removing stone fragments. By incorporating this innovative feature, the ClearPetra System ensures efficient stone clearance without the need for additional accessory devices or complex procedures.

Improved Visual Field

Continuous irrigation and suction offered by ClearPetra result in an improved visual field during lithotripsy procedures. Bleeding and dust storm effects from stone pulverization are significantly reduced, enhancing the surgeon’s visibility and precision throughout the treatment process.

Enhanced Stone Clearance

Utilizing the oblique side port on the ClearPetra Sheath, stone fragments aggregate at the distal end, avoiding scattering. Continuous suction facilitates the removal of stone fragments, ensuring superior stone clearance and streamlining the procedure.

Uncomplicated Procedure

ClearPetra eliminates the requirement for stone baskets, forceps, or anti-retropulsion devices. Through Negative Pressure Aspiration, stone fragments are efficiently evacuated, simplifying the procedure and improving workflow for healthcare professionals.
