    Abstract: A medical insertion device includes an elongated shaft extending from a proximal end to a distal end and having flexibility sufficient for insertion through a working channel of an endoscope along a tortuous path. The elongated shaft includes a coil extending from the proximal end to the distal end and having a channel extending longitudinally therethrough and a braided portion extending around a portion of the coil, the braided portion including a plurality of lines wound together such that first and second ones of the lines intersect to enclose a predetermined angle therebetween, the angle being between 25 and 55 degrees.

    Abstract: A device for causing hemostasis includes a sheet of mesh stretchable between an expanded and a retracted configuration, a size of the sheet in the retracted configuration being selected to cover a target tissue site; a spring mechanism coupled to the mesh, the spring mechanism moving between an expanded configuration and a retracted configuration when the mesh is moved between the expanded and retracted configurations; and a plurality of hooks coupled to the mesh and oriented to extend into tissue to lock the mesh in position when the mesh is placed in a desired position over the target tissue site in the expanded configuration. The hooks are lockingly engaging the target tissue so that, after the hooks have lockingly engaged the tissue, the spring mechanism reverts to the retracted configuration drawing the engaged portions of tissue radially inward.

    Abstract: A device for treating a tissue includes a capsule extending longitudinally from a proximal end to a distal end and including a channel extending therethrough, clip arms, proximal ends of which are slidably received within the channel of the capsule so that the clip arms are movable between an open configuration, in which distal ends of the clip arms extend distally past the distal end of the capsule to be separated from one another, and a closed configuration, in which the clip arms are restrained via an interior surface of the capsule so that distal ends of the clips arms are drawn toward one another, and a reinforcement element coupled to the clip arms, the reinforcement element preventing deflection of the clip arms when engaging a target tissue.
