Abstract: A clipping device includes a capsule including a longitudinal body and a cap mounted over a distal end thereof so that the cap is movable relative to the longitudinal body from a pre-deployed configuration to a deployed configuration in which the cap, is moved proximally relative to the longitudinal body to reduce a length of the capsule. A channel of the cap and a channel of the capsule are substantially aligned with respect to one another. At least proximal portions of a pair of clip arms are received within the channels of the cap and the longitudinal body so that the clip arms are movable relative to the capsule 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.

Abstract: A medical device that comprises an enclosure defining a cavity for containing an agent, a lumen for receiving a pressurized fluid, a channel between the cavity and the lumen, and a barrier positioned in the channel and defining a space, wherein in a first position of the barrier, the space is in fluid communication with the cavity to receive the agent from the cavity, and wherein the barrier is configured to rotate from the first position to a second position in which the space is in fluid communication with the lumen to deliver the agent from the space to the lumen.

Abstract: A clipping device includes a clip including a capsule and a pair of clip arms, proximal ends of which are slidably received within the channel to move the clip arms between an open configuration and a closed configuration. Each of the pair of clip arms includes an elongated opening extending through the proximal ends thereof. A connector includes a central portion received between the proximal ends of the clip arms and a pin extending from the central portion receivable within the opening of each of the clip arms, the connector movable from an unlocked configuration, in which the pin is received within a distal portion of the elongated opening, to a locked configuration, in which the pin is received within a proximal portion of the elongated opening, when a predetermined force is applied thereto.

Abstract: A system includes a clip having a pair of clip arms, proximal ends of the clip arms received within a channel of a capsule to be moved between an open configuration and a closed configuration. A proximal end of the capsule including a plurality of connecting elements extending proximally therefrom. Each of the connecting elements including a hook along a proximal portion thereof. An applicator includes an elongated flexible member and a control member extending therethrough, the control member configured to be connected to the clip arms to move the clip assembly between the open and closed configurations, the elongated flexible member including a bushing including a first ramped portion and a necked portion extending proximally from the first ramped portion, a proximal end of the first ramped portion including a lip configured to engage the hook when the connecting elements are crimped thereover.

Abstract: A clipping system includes a clip having a pair of clip arms, proximal ends of the clip arms slidably received within a channel of a capsule to be moved between an open configuration and a closed configuration. A proximal end of the capsule including connecting tabs extending proximally therefrom. An applicator includes an elongated flexible member and a control member extending therethrough. The control member includes a distal end connected to the clip arms to move the clip assembly between the open and closed configurations. A distal end of the elongated flexible member includes a bushing including a first ramped surface, along which the connecting tabs slide along to engage a corresponding engaging feature of the bushing, and a second ramped surface proximal of the first ramped surface, the connecting tabs slidable along the second ramped surface to plastically deform toward a deployed configuration.

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.
