Olympus Corporation announced a voluntary medical device corrective action for its Single-Use Ligating Device ("PolyLoop") following identification of a potential safety issue. The PolyLoop device is designed for use with Olympus endoscopes to deliver a nylon loop snare intended to prevent or control bleeding following polypectomy of pedunculated polyps. Olympus took this action after receiving adverse event reports indicating that the PolyLoop may fail to release or detach as expected during use, resulting in the loop becoming unintentionally anchored around patient anatomy.
No deaths have been reported. An unreleased ligation loop can present procedural challenges, requiring emergency intervention for removal from patient's anatomy. Risks include bleeding, mucosal injury, perforation, and in severe cases, the need for surgical intervention or hospitalization.
