Testing of GripTract-GI Endoscopic Tissue Manipulator for Use During Complex Endoscopic Polypectomies in the Colon

The goal of this clinical trial is to compare the safety and effectiveness of the GripTract GI Endoscopic Tissue Manipulator to the current standard of care for complex polypectomies in adults. The main questions it aims to answer are: 1. How does the number and severity of Device-Attributable Adverse Events compare to the current standard of care? 2. How is the procedure time affected? 3. Is the ability to resect the tissue en bloc affected? 4. What is the user feedback on the device performance?
