Designed to replace partial or total loss of one's fingers, these custom-designed and fabricated Prosthetic Fingers are powered by the remainder of each finger. Three different devices are available: the PIPDriver (for amputees who still have their middle joint), the MCPDriver (for amputees with finger loss closer to the knuckle joint), and the ThumbDriver (for amputees with loss of the thumb). Consisting of medical-grade nylon, titanium fasteners, and silicone-rubber tip pads, every prosthetic finger is reportedly custom-designed to within millimeters of a patient's unique amputation and hand structure.
