Patent ID: 8162959

Claim:
A tissue clipping apparatus, comprising: a clip including a proximal end received within a capsule, the clip including 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; and a tension member releasably coupling the clip to a proximal end of the apparatus which, during use, remains accessible to a user, the tension member being coupled to the clip by a joint designed to release when subject to a predetermined load to separate the clip from the apparatus, release of the joint releasing the locking member to engage the first locking structure; a constraint member coupled to the tension member and releasably connected to the clip, wherein when coupled to the clip, the constraint member maintains the locking member of the clip out of engagement with the first locking structure of the capsule, release of the joint allowing the constraint member to move to a release position releasing the locking member to engage the first locking structure; a proximal member extending from the proximal end of the apparatus to releasably couple to the capsule, a distal end of the proximal member comprising a bushing releasably coupled to the capsule, the bushing comprising a bushing locking feature biased toward an unlocked position and a support received within the bushing to urge the bushing locking feature into engagement with a second locking structure of the capsule.
