inert biocompatible material that includes resilient elastic properties such abs stainless steel or titanium abs is suitable as a single use disposable surgical tool while stainless steel or titanium could be steam sterilized and reused once the electrode array body 4 and the feeder cable 18 are safely held in the surgical tool 50 the surgeon can pass the tool 50 electrode array body 4 and the feeder cable 18 in the same manner as a needle and thread the preferred surgical tool 50 is curved to promote easy movement around the eye the curvature of the tool generally conforms to the curvature of the outside of the sclera alternatively the surgical tool may be strait as shown in fig9 fig9 shows an alternate embodiment of the surgical tool 150 the alternate surgical tool 150 has a strait base 54 and top 58 while retaining the radius 164 and rounded point 152 of the preferred embodiment there are advantages to strait and curved surgical tools for much the same reasons there are advantages to strait and curved needles different surgeons may prefer different tools fig1 shows another alternate embodiment rather than relying on spring force to hold the electrode array body 4 and the feeder cable 18 in the tool 250 the base 254 is rigidly attached to the rounded point 252 but the top 258 is attached by a hinge 256 to the base 254 and rounded point 252 this allows the surgeon more control of the force applied to.
