Patent number: 10905434Abstract: A system for treating tissue includes a clip assembly having a pair of clip arms. Proximal ends of the clip arms engage a distal portion of a central member slidably received within a channel of a capsule to be moved between an open configuration and a closed configuration. The central member includes the distal portion and a proximal portion connected to one another via a releasable connection which releases when subject to a force exceeding a predetermined threshold level. The system also includes an applicator releasably coupled to the clip assembly. The applicator includes an outer sleeve through which a control member extends.
