The invention relates to a universal auxiliary controller for an injection molding machine, comprising an operating panel, a machine controller coupled to the operating panel, a converter acted on by the machine controller, a controllable electric motor that can be actuated by the converter, and a resolver. The elongate shaft may be bent along its complete length into any shape and remain fixed in that shape to accommodate compact storage as well as forming a grasping and twisting handle for the shaft while it is in the drain or bending the hair-snagging end of the shaft for easier insertion and navigation within the drain. An inflation lumen is in fluid communication with the primary valve body outlet and an interior of the cuff or balloon. An interface box is removably attached to a lower surface of the seat portion for electrically connecting the speakers and controller to a conventional game box. The present invention provides an alcohol solvate, such as ethanol solvate, of a disodium salt of a delivery agent of the formula above. The method of the present invention uses a microkeratome having a blade that is capable of cutting through the epithelial layer and Basement Membrane, but not capable of cutting through Bowman’s Membrane.
