It is indicated for fractures, and inter-digital fusion of the fingers, toes and small bones. ## Device Story StayFuse is an intramedullary bone screw consisting of two components: a male half with a protruding connection and a female half with an internal connection. The bone-mating portion features a cancellous thread with a self-drilling and tapping tip. An external hex distal to the screw tip allows engagement with a dual-purpose hex driver, which is used for both pre-drilling the bone and inserting the implant. The driver is designed to interface with a standard cannulated drill chuck. The device is available in various diameters, lengths, and hex drive configurations to accommodate bone size variability. It is intended for use by clinicians for small bone fusion and fracture fixation. Not intended for spinal use. ## Clinical Evidence bench testing only ## Technological Characteristics Intramedullary bone screw; cancellous thread design; self-drilling/tapping tip; external hex interface; dual-purpose hex driver; cannulated drill compatibility; various diameters and lengths. ## Regulatory Identification A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system. ## Predicate Devices - K-Wire ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
