The capsule is releasably coupled to a proximal portion of the device. Device also includes a first arm rigidly fixed to the distal end of the capsule to extend distally therefrom. In addition, Device includes a second arm, a proximal end of which is slidably received within the capsule so that the second arm is movable between an open configuration, in which the second arm is moved laterally away from the first arm and a distal end of the second arm is moved distally past the distal end of the first arm, and a closed configuration, in which the second arm is moved toward the first arm and the distal end of the second arm is moved proximally toward the distal end of the first arm. ## Claims ### Claim 1 A method for treating a tissue defect, comprising: inserting a clipping device, in a closed configuration, to a target area within a living body via a working channel of an endoscope, the clipping device including a capsule, a first arm rigidly fixed to a distal end of the capsule and extending distally therefrom and a second arm movably received within the capsule; moving the clipping device from the closed configuration to an open configuration, in which the second arm is moved laterally away from the first arm and a distal end of the second arm is moved distally past a distal end of the first arm; capturing a first portion of tissue along a first side of a tissue defect with the distal end of the first arm; moving the clipping device toward a second portion of tissue along a second side of the tissue defect, the second side opposing the first side; grasping the second portion of tissue with the distal end of the second arm; and moving the clipping device toward the closed configuration, in which the second arm is drawn laterally toward the first arm and the distal end of the second arm is drawn proximally toward the distal end of the first arm so that the second portion of tissue is drawn toward the first portion of tissue, thereby closing the tissue defect. ### Claim 2 (depends on 1) The method of claim 1, wherein the clipping device is moved toward the closed configuration prior to moving the clipping device toward the second portion of tissue and is moved toward the open configuration prior to grasping the second portion of tissue. ### Claim 3 (depends on 1) The method of claim 1, further comprising: locking the clipping device in the closed configuration and deploying the clipping device. ### Claim 4 (depends on 1) The method of claim 1, wherein the clipping device is moved between the open and closed configurations via a control element releasably coupled to a proximal end of the second arm, the control element being released from the second arm to deploy the clipping device. ### Claim 5 (depends on 4) The method of claim 4, further comprising: after the clipping device has been locked in the closed configuration, separating the clipping device from a proximal applicator. ### Claim 6 (depends on 5) The method of claim 5, wherein the proximal applicator includes a further control element operable to move the clipping device between the open and closed configurations, and wherein the clipping device is separated from the proximal applicator by applying a force above a predetermined threshold level so that the clipping device remains within the body and the proximal applicator is removed therefrom. ### Claim 7 (depends on 4) The method of claim 4, further comprising separating the control element from the second arm to allow a locking tab of the second arm to engage the capsule, thereby locking the second arm relative thereto, in the closed configuration. ### Claim 8 (depends on 1) The method of claim 1, wherein, in the closed configuration, the distal ends of the first and second alms are substantially longitudinally aligned. ### Claim 9 (depends on 1) The method of claim 1, wherein the first portion of tissue is captured on a barb formed at the distal end of the first arm. ### Claim 10 (depends on 1) The method of claim 1, wherein the first portion of tissue is captured on a hook formed at the distal end of the first arm. ### Claim 11 (depends on 1) The method of claim 1, wherein the first arm extends along an axis substantially parallel to a longitudinal axis of the capsule. ### Claim 12 (depends on 1) The method of claim 1, wherein the distal end of the first arm includes a tissue piercing member extending laterally inward toward the second arm. ### Claim 13 (depends on 1) The method of claim 1, wherein the second arm is biased toward the open configuration and is restrained via an interior surface of the capsule in the closed configuration. ### Claim 14 (depends on 1) The method of claim 1, wherein an interior surface of the first arm is curved so that longitudinal edges thereof extend toward the second arm to form a cupped tissue receiving pocket. ### Claim 15 (depends on 14) The method of claim 14, wherein the interior surface includes one or more of teeth, spikes, grooves and a textured surface to grip tissue received between the first and second arms. ### Claim 16 (depends on 1) The method of claim 1, wherein the second arm is formed of a compliant material. ### Claim 17 (depends on 16) The method of claim 16, wherein the compliant material includes one of Nitinol and Stainless Steel.
