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