Abstract
A system for treating tissue includes a clip assembly including a pair of clip arms. Proximal ends of the clip arms are slidably received within a channel of a capsule to be moved between a tissue receiving configuration and a tissue clipping configuration. The system also includes a catheter assembly including a control member extending therethrough. The control member includes a distal end connected to the clip arms to move the clip assembly between the receiving and clipping configurations. The system further includes a coupler releasably coupled to a proximal end of the capsule and configured to be coupled to the distal end of the catheter assembly. The coupler fractures when a proximal force exerted on the coupler via the control member exceeds a first predetermined threshold value to disengage the capsule and deploy the clip assembly.
