The ClearPetra Ureteral Access Sheath is an innovative medical device designed to enhance the safety and efficiency of lithotripsy procedures. This specialized sheath plays a pivotal role in managing intra-renal pressure (IRP), a critical factor in preventing complications during kidney stone treatments. ClearPetra from Wellead offers surgeons a solution that maintains a safe IRP while ensuring a clear visual field, which is essential for successful stone fragmentation and removal.

How ClearPetra Enhances Control Over Intra-Renal Pressure (IRP) 

During lithotripsy, maintaining a safe IRP is crucial to prevent damage to kidney tissues. The ClearPetra Ureteral Access Sheath helps achieve this by preventing the elevation of IRP beyond the safety threshold of 30 mmHg. With its unique design, ClearPetra features a 45° oblique branch that can be connected to a suction apparatus. This feature allows surgeons to actively control the IRP without compromising the visual field or efficiency of the procedure.

Mechanism and Benefits of the ClearPetra Design 

The ClearPetra Ureteral Access Sheath boasts a unique mechanism for effective irrigation and stone fragment evacuation. As irrigation fluid flows through the endoscope, a vortex is created at the distal end of the sheath. This vortex efficiently removes stone fragments, blood, and debris through suction, ensuring a clear visual field for the surgeon. Additionally, the pressure vent on the oblique side branch of the sheath allows for precise control over suction pressure, further enhancing operational safety and effectiveness.

Conclusion

In conclusion, the ClearPetra Ureteral Access Sheath is a revolutionary tool that enhances the precision and safety of lithotripsy procedures, ensuring better outcomes for both patients and medical professionals.
