  • Patent number: 9895154
    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.

  • Patent number: 8915837
    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.
