  • Patent number: 11517316
    Abstract: A system for treating tissue includes a clip assembly including clip arms movable relative to a channel of a capsule so that the clip arms are movable between a tissue receiving configuration and a tissue clipping configuration. Also, the system includes an applicator releasably coupleable to the clip assembly. The applicator includes a bushing and a control member extending therethrough. The bushing includes deflectable fingers, each of the fingers including an engaging feature at a distal end thereof to engage a corresponding engaging feature of the capsule of the clip assembly and assembled with a pusher element configured to push the fingers to a radially outward position. The pusher element includes a U-shaped portion curving into a channel of the bushing and a longitudinal portion extending distally therefrom. A cam washer is slidable over a length of the control member and positioned distally of the U-shaped portion.

  • Publication number: 20190282219
    Abstract: A biopsy forceps device includes a tension member and an end effector including first and second jaws movable between an open configuration, in which the jaws are separated from one another to receive target tissue therebetween, and a closed configuration, in which cutting edges of the jaws are moved toward one another to cut a portion of the target tissue. The jaws define a tissue receiving space therebetween to house the cut tissue. The jaws are pivotable relative to one another, each of the jaws including a serrated cutting edge extending therealong, the end effector further including a tension member attachment including a proximal end coupled to the tension member. The attachment is movably coupled to the jaws so that distal movement of the attachment moves the jaws to the open configuration while proximal movement thereof moves the jaws to the closed configuration.

    Abstract: A biopsy forceps device includes a tension member and an end effector which includes jaws movable between an open configuration, in which the jaws are separated from one another to receive target tissue therebetween, and a closed configuration, in which cutting edges of the jaws are moved toward one another to cut a portion of the target tissue from surrounding tissue. The jaws defines a tissue receiving space therebetween to house the cut tissue. The jaws are pivotable relative to one another. The end effector further includes a tension member attachment coupled to the tension member; a distal end of which terminates at a sharp spike configured to penetrate the tissue. The attachment is movably coupled to the jaws so that distal movement of the attachment moves the jaws to the open configuration, while proximal movement thereof moves the jaws to the closed configuration.
