Abstract
A system and method for treating tissue includes an applicator including a bushing and a control member. The control member extends through the bushing to an enlarged distal end. The system also includes clip assembly releasably coupleable to the applicator. The clip assembly includes clip arms and a yoke including a distal portion connected to the clip arms and a proximal portion. The proximal portion includes a slot configured to receive the enlarged distal end of the control member and at least one helical cut positioned at a proximal end of the slot. The helical cut is configured to rotate the enlarged distal end from a first orientation in which the enlarged distal end is offset from the slot to a second orientation in which the enlarged distal end is aligned with the slot so that when a force thereon exceeds a threshold value, the enlarged distal end passes into the slot.
