Since the original BCHI design, a number of different devices have been marketed but the focus of this paper will be on currently available devices. They can be categorized into 2 main groups: skin-drive and direct-drive devices. Direct-drive devices include products such as the Bone Anchored Hearing Aid (BAHA; Cochlear Bone Anchored Solutions), Ponto (Oticon Medical) and the Bonebridge (Vibrant MED-EL, Innsbruck, Australia). These devices vibrate the skull via direct contact with the bone. Direct-drive devices can be subdivided into: percutaneous devices, where an abutment is used (such as the BAHA and Ponto) and active transcutaneous devices, where the transducer is implanted (such as the Bonebridge). Skin-drive devices, including the Sophono and BAHA Attract, do not have a continuous link with the bone as vibrations are transmitted through the skin to an implanted magnet instead.
