Abstract
A system may include a retractor movable between a radially-collapsed configuration and a radially-expanded configuration, a retraction tool having a tissue-engaging element and an anchor-engaging element, and a first member configured to form a releasable coupling with the anchor-engaging element at each of a plurality of spaced apart positions.
Claims20
A system, comprising:
- a retractor movable between a radially-collapsed configuration and a radially-expanded configuration;
- a retraction tool having a tissue-engaging element and an anchor-engaging element;
- and
- a first member configured to form a releasable coupling with the anchor-engaging element at each of a plurality of spaced apart positions.

A system, comprising:
- an overtube having a lumen configured to receive an endoscope;
- a retractor at or adjacent to a distal end of the overtube, the retractor being movable between a radially-collapsed configuration and a radially-expanded configuration;
- and
- a tool having a shaft and a tissue-engaging element coupled to a distal end of the shaft by a tether, wherein the distal end of the shaft is sloped relative to a proximal end of the shaft.
1 more element
A method of treating a patient, the method comprising:
- radially expanding a retractor while the retractor is adjacent to a target area in a body lumen of the patient;
- grasping tissue with a tissue-engaging element of a retraction tool;
- and
- tensioning the tissue by securing an anchor-engaging element, coupled to the tissue-engaging element, to a first anchor element of a plurality of spaced apart anchor elements.
