Photochemical machining process by Tech-Etch produces burr-free, intricate components from specialty materials used in medical implants and implantable devices. Nitinol is used for stents and surgical fixation applications. Titanium, which is inert and biocompatible, is used in maxillofacial and craniofacial reconstruction plates, as well as anode and cathode battery current collectors and telemetry antennas found in implanted medical devices. Elgiloy is employed for stiffener bands in high fatigue applications. Tungsten is used for grids to collimate and attenuate stray x-rays in CT scanners, as well as ID tags for implanted medical devices, because it is extremely dense—71% heavier than lead. Polyimide is etched to produce haptics for intraocular lens implants in cataract surgery and other corrective implants. Tech-Etch also manufactures custom flexible printed circuits found in implanted cardio defibrillators, pacemakers, and neurostimulation devices. Parts range in thickness from .0005 in. and up. Designs can be proved in preproduction quantities and without expensive tooling. Laminating, plating, heat treating, and assembly are offered in-house.
