Tissue Clipping Device

Abstract

The device includes a flexible insertion section extending from a distal end that is inserted into the target site during use to a proximal end that remains outside the living body, an end effector coupled to the distal end of the insertion section, and a control wire received within the insertion section and extending from a proximal end coupled to the actuator to a distal end coupled to the end effector. The control wire is movable within the insertion section to operate the end effector. The control wire and insertion section include a bend at their distal portions that, in a rest state, cause the control wire and insertion section to bend through a predetermined arc with a selected bend radius. The distal portion of the control wire enters and passes through the working channel of the insertion device without plastic deformation of the control wire.
