A transcutaneous prosthetic device having at least one soft tissue fixture adapted to be fixed to the musculo-tendinous soft tissues of a residual limb, an anchor for an external prosthesis that is fixedly coupled, directly or indirectly, to the bone of the residual limb and at least one transmission means, at least part of the transmission means being housed within a body. The transmission means allowing transmission of one or more signals between the soft tissue fixture and an external prosthesis. The transmission means may comprises a connecting means connecting the soft tissue fixture and an external prosthesis. The connecting means may comprise a mechanical or an electrical connector. The connecting means may comprise a sealed connection within the transcutaneous component, to provide an effective barrier between the internal and external environments.
