Abstract: A system includes Adapter, Clip, Member, Wire and Mechanism. Adapter includes a proximal portion mounted over a distal end of an insertion device and a distal portion extending distally from the proximal portion. Clip includes Jaws to move between insertion configuration, in which Jaws extend about Adapter and are separated to receive tissue, and initial configuration, in which Clip is moved distally off of Adapter so that Jaws grip tissue. Member is releasably coupled to Clip and movably connected to Adapter. Member extends from a proximal portion to remain, in an operative configuration, outside body to a distal portion to be coupled to the distal end. Wire is received within Member and extends to a distal end releasably coupled to Clip via Link when predetermined force is applied. Mechanism selectively locks the distal portion of Member against proximal movement relative to Adapter during release of Link.

Abstract: An assembly and/or system having a cutting device configured to cut tissue, and an inflatable device configured for insertion into the cut tissue to further separate the cut tissue. The inflatable device may be wedge shaped to separate the cut tissue upon insertion into the cut. The inflatable device is inflatable and otherwise adjustable to separate the tissue to a medically indicated extent. For instance, the inflatable device may be moved axially with respect to the cutting device; and/or may be sheathed or unsheathed to adjust an exposed inflated length thereof; and/or may include two or more separately inflatable elements. The inflatable device thus may be used to achieve blunt tissue dissection after an initial cut is made into the tissue with a sharper instrument.

Abstract: A clip includes first and second jaws, first and second hinges, and a connection portion. Each of the jaws extends along a curve from a first end to a second end.

The first and/or second hinges is/are biased to draw the clip toward the closed configuration. The portion connects an end of each of the hinges to a corresponding one of the first and second ends. The connecting includes an engaging feature engaging via a through-the scope device to extract the clip from a tissue over which it has been clipped upon a deployment thereof.
