Abstract: A surgical tool with an elongated implement of enhanced stiffening character due to the use of a stiffening coating and/or a lumen of inconsistent diameter. The stiffening coating may be supplied by a deposition technique utilizing materials tailored to biocompatibility, stiffening and even to reducing glare. The lumen of inconsistent diameter may include a distal end taking up a minority of the lumen that is of a larger diameter than a proximal portion of substantially smaller diameter for increasing wall thickness and stiffening of the majority of the implement.
