Abstract

Systems, methods, and devices for assisting submucosal dissection include a shrink tape body. The shrink strap body is at least partially formed from a deformable material. The shrink strap body is selectively movable between a first state and a second state. In the first state, the constriction band body is capable of engaging target patient tissue. In the second state, the constriction band body is capable of constricting the target patient tissue. At least one tissue engaging member is located on the constriction band body.

Description

[0001] related application [0002] This application claims priority to U.S. Provisional Application No. 62 / 293,505, filed February 10, 2016, and U.S. Provisional Application No. 62 / 281,215, filed January 21, 2016, the subject matter of which is incorporated by reference in its entirety. The content is incorporated into this article. technical field [0003] The present disclosure relates to an apparatus, method, and system for assisting submucosal dissection, and more particularly, to a tissue retraction device and method of use. Background technique [0004] Endoscopic submucosal dissection ("ESD") is an endoscopic technique in which an endoscope is used to dissect a lesion, such as but not limited to early gastrointestinal cancer. One challenge in performing ESD is the absence of a second hand that can provide traction and counter-traction as in conventional surgery. Providing a device that can act as a surgeon's second hand can allow ESD to be performed more efficientl...
