Abstract:
The present disclosure provides a system and method for removing a tissue that extends from a tissue layer, such as a polyp, lesion, or organ. The disclosure provides a medical loop that can be tightened around the tissue extending from the tissue layer by using a one-way anchor and a flexible member to form a loop, the flexible member having ridges to interface with the anchor and secure the flexible member in a tightened position around the tissue. The ridges interface with the tissue to secure the loop in position on the extending tissue and reduce slippage of the loop off of the tissue after tightening the loop. A snare or other cutting instrument may be used to remove the tissue extending outward from the loop. An endoscopic system may be used to guide the medical loop and the cutting instrument to an appropriate location inside a body passage.
