Hemostasis clip deployment

A clipping system, comprising:

• an applicator including a flexible shall extending from a proximal end which, in an operative configuration, remains outside a living body to a distal end which, in the operative configuration, is inserted into the living body to a site adjacent to target tissue to be clipped;
• a clip releasably coupled to the applicator via a bushing at the distal end of the flexible shaft, the clip including:
• a capsule including a channel extending therethrough;
• and
• a pair of clip arms, proximal ends of which are slidably received within the channel of the capsule to move the clip arms between an open configuration, in which distal ends thereof are separated from one another, and a closed configuration, in which the distal end of the clip arms are drawn toward one another;
• and
• a control member extending through the flexible shaft from a proximal end to a distal end releasably coupled to the proximal ends of the clip arms to move the clip arms between the open and the closed configurations, the distal end including a middle portion received between the proximal ends of the clip arms, a first portion of a pin and a second portion of the pin extending away from opposing surfaces of the middle portion to be received in openings extending through proximal ends of the clip arms to maintain an alignment of the clip arms relative to one another, the first and second portions being pulled proximally out of the openings of the clip arms and past a proximal edge thereof when a predetermined force is exerted on the clip arms via the distal end.

A method for treating a target tissue, comprising:

• inserting a clip device through a working channel of a flexible insertion device to a target site within a body until a clip of the clip device extends distally past a distal end of the working channel, the clip device including an applicator including a flexible shaft extending from a proximal end to a distal end, a capsule and a pair of clip arms slidably received therein, the pair of clip arms being aligned relative to one another via a pin extending through openings extending through proximal ends of the clip arms;
• moving the clip device between an open configuration, in which distal ends of the clip arms are separated from one another, and a closed configuration, in which the distal ends of the clip arms are drawn toward one another, via a control member coupled to the clip anus, until target tissue is received between the distal ends of the clip arms, a distal end of the control member being coupled to the proximal ends of the clip arms via first and second holding jaws, each of which includes a pair of fingers extending about and gripping the pin along opposing sides;
• drawing the clip arms proximally into the capsule to move the clip toward the closed configuration to grip the target tissue between the clip arms;
• and
• deploying the clip by drawing the control member proximally relative to the capsule until a predetermined force is exerted on the distal end of the control member to spread the fingers apart from one another releasing the pin from therebetween and separating the clip from the applicator.
