Publication number: 20220202436Abstract: An elongated tissue traction device adhered to target tissue and configured to lift the target tissue away from surrounding tissue. The tissue traction device may lift the target tissue as a surgical procedure is performed, such as resecting or cutting of the target tissue. The tissue traction device may be a bistable spring. The tissue traction device is in a first stable configuration when initially adhered to the target tissue. The tissue traction device may be shifted (e.g., actuated) into the second configuration, such as when the tissue is resected or cut around the target tissue to which the tissue traction device is adhered. In the second stable configuration, the tissue traction device curls and lifts the target tissue from the surrounding tissue.Type: ApplicationFiled: December 1, 2021Publication date: June 30, 2022Inventors: Nabarun Bhowmick, Deepak K.
