Abstract
A sheath defines a lumen. A mesh portion is coupled to the sheath and is movable between a retracted position and an expanded position. An elongate member is disposed in the lumen and is operably attached to one of the mesh portion and the sheath such that longitudinal movement of the elongate member within the lumen causes movement of the mesh portion between the expanded position and the retracted position. The sheath and the mesh portion are introduced into the body along with an end effectuator. The mesh portion is moved to its expanded position to form an object supporting surface. The surface is used to support an object, such as a stone, during a medical treatment procedure using the end effectuator.
