Abstract: An applicator of a clip system includes an elongated member and a bushing coupled to a distal end of the elongated member and a coupling movably attached to the bushing. A capsule is coupled to the coupling via a coupling member hooked over a hook of the coupling. Proximal ends of clip arms are received within the capsule and a core member received between and connected to the proximal ends of the arms includes a projection and a failure point distal of the projection. The core member is coupled to a control member so that movement of the control member relative to the elongated member opens and closes the arms. The projection is configured so that, when the clip is clipped over tissue, the coupling is drawn into the body and the projection drives the coupling member radially outward off the hook to free the capsule.

Abstract: A tissue traction device having a segment defined along a limited extent about the perimeter of the tissue traction device and more flexible than surrounding regions of the tissue traction device. The tissue traction device is actuatable to bend along the more flexible segment thereof, generally in a direction of a side of the tissue traction device opposite the more flexible segment thereof. The tissue traction device may be formed from one or more flexible tubular elements, with the flexible segment along a limited extent about the perimeter of the one or more tubular elements. A tissue traction system may be configured to provide actuation medium, such as an inflation medium, to the tissue traction device to control movement of the tissue traction device. The tissue traction system may include one or more flexible tubular elements, a distal end of which forms the tissue traction device.

Abstract: A clipping system includes a clip, a core member and a control member. The clip includes a capsule extending longitudinally from a proximal end to a distal end and including a channel extending therethrough, and clip arms. Proximal ends of the arms are slidably received within the channel to move the arms between open and closed configurations. The core member is received between and connected to the proximal ends of the arms to couple the arms to one another. The core member includes a locking feature movable between unlocked and locked configurations. The control member extends through a proximal portion of the system from a proximal end to an enlarged distal end housed within a proximal portion of the core member so that a longitudinal movement of the control member relative to the capsule moves the clip between the open and closed configurations.
