The GV Connector serves as a lower limb interface between an osseointegrated intramedullary implant and a standard commercial prosthesis. The device aims to help restore mobility for amputee patients by providing a link of an artificial extension of the patient’s amputated limb. Proximally, the connector is attached to the taper sleeve / anti-rotation locking washer construct of the Osseointegrated implant system. Distally, the connector features a standard four-hole threaded connection commonly used in the prosthetic industry, allowing it to be attached to a standard leg prosthesis.
