Abstract: An apparatus for deployment of a hemostatic clip comprises a handle assembly, a shaft connected to a distal portion thereof and a clip assembly releasably coupled to a distal portion of the shaft. The clip assembly includes clip arms and a capsule cooperating with the clip arms to provide a first user feedback indicating a decision configuration of the clip assembly. In addition, the apparatus includes a control wire including a ball connector, the control wire extending from the handle assembly and coupled to the clip assembly by the ball connector to maintain the clip assembly coupled to the shaft, wherein the ball connector is detachable from the clip assembly to provide a second user feedback indicating separation of the clip assembly from the shaft.

Abstract: A hemostatic clip assembly for mounting on a delivery device comprises a capsule and a clip slidably mounted within the capsule so that, when the clip is drawn proximally into the capsule, arms of the clip are drawn together to a closed position, an abutting surface of at least one of the arms contacting a corresponding surface of the capsule when the clip is drawn to a predetermined position within the capsule to provide a first user feedback indicating closure of the clip in combination with a tension member connected to the clip arms and biasing the clip arms toward an open, tissue receiving configuration and a yoke slidably received within the capsule and releasably coupled to the tension member, the yoke including a ball cavity for receiving a ball connector of a control element of the delivery device to maintain the clip assembly coupled to the delivery device, wherein the control element is frangible to detach the yoke from the delivery device and to provide a second user feedback and, wherein release of the yoke from the tension member provides a third user feedback.

Abstract: A tissue clipping apparatus, comprises a flexible, elongate member, a proximal end of which remains external to the body accessible to a user while a distal end of the flexible member is inserted into the body to a location adjacent to target tissue to be clipped and a control wire extending through the flexible member in combination with a capsule releasably coupled to a distal end of the flexible member and a clip a proximal portion of which is received within the capsule. A joint releasably coupling the clip to the control wire, includes a yoke extending around a proximal end of the clip and a frangible link which fails when subject to a predetermined force to separate the clip from the control wire.

Abstract: A tissue clipping apparatus comprises a clip including a proximal end received within a capsule. The clip includes a clip locking member biased to engage a first locking structure of the capsule to lock the clip in the capsule in a closed configuration. The apparatus also comprises a tension member releasably coupling the clip to a proximal end of the device which, during use, remains accessible to a user. The tension member is coupled to the clip by a joint designed to release when subject to a predetermined load to separate the clip from the device, release of the joint releasing the locking member to engage the first locking structure.
