Abstract:
1. A device for facilitating access to a perimeter surface of a body structure comprising: an elongate flexible member configured to be positioned adjacent the perimeter surface of the body structure; an atraumatic tip positioned at a distal end of the elongate flexible member and having a width greater than that of the flexible member; an elongate body having a surface positioned to guide the elongate flexible member and to permit longitudinal movement of the flexible member with respect to the elongate body, wherein the elongate flexible member extends within the elongate body of the device, the body having a curved distal portion and a distal end releasably engaging the atraumatic tip; a handle coupled to the elongate body, wherein the elongate body extends at least partially within the handle; a depressible trigger that is moveably positioned with respect to the handle; and a hook connected to the trigger and positioned within an opening that is defined within the elongate body, wherein, when the trigger is depressed, the hook is spaced from an inside surface of the elongate body and the elongate flexible member is released to permit relative movement of the elongate flexible member with respect to the elongate body, and, when the trigger is not depressed, the elongate flexible member is held against the inside surface of the elongate body by the hook to either prevent or limit relative movement of the elongate flexible member with respect to the elongate body.
