A percutaneous gateway is provided for permanently transmission between inside of a body and outside of the body, comprising an implant (10) adapted to be at least partly anchored in a bone (1). The implant (10) has a transmission means (30) that allows a long-term stable communication through a transmitting device (20) adapted to extend from an implantable component (90) through the bone (80) to a device (91) at the outer end (3) of the percutaneous gateway.

An apparatus, adapted for resiliently holding resected fibula sections, comprises: a first connecting portion adapted for connecting a first resected fibular section of a patient's fibula; a second connecting portion adapted for connecting a second resected fibular section of the patient's fibula; and an elastic portion or member defined between the first connecting portion and the second connecting portion adapted for resiliently holding the first resected fibular section and the second resected fibular section, whereby upon actuation by an impacting force caused by the patient's movement, the elastic portion may resiliently buffer such an impacting force to prevent contacting or rejoining of the first and second resected fibular sections.

The present invention comprises devices, systems, and methods for elongating bone using an extension implant having a first end and a second end. The first end of the extension implant is inserted into an opening in the live bone and the second end of the extension implant is combined with an enlarged implant. A plurality of channels extend through the components to serve as conduits for delivering fluids and physiological signals which induce bone formation. Some embodiments include a subcutaneous cage assembly for helping to support the implant as the bone heals around it.

An osseointegrated abutment support socket for a residual limb in which an osseointegrated abutment has been implanted is described. The osseointegrated abutment support socket may include a distal socket base assembly, multiple longitudinal struts and a percutaneous site protector. The distal socket base assembly may include a base plate, a collar extending proximally from the base plate and forming a receptacle for receiving a distal end of the osseointegrated abutment, and a strut support ring disposed around the collar. The struts are connected at their distal ends to the strut support ring and extend proximally upward. The percutaneous site protector contacts a distal surface of the residual limb near a percutaneous site where the distal end of the osseointegrated abutment exits the residual limb.

An implant assembly for a long bone is adapted to support an exo-prosthesis. The assembly includes a stem, a subdermal component and a percutaneous post. The stem has a proximal end that is adapted to be received in a surgically prepared medullary canal of the long bone, and a distal end having a surface that is adapted to promote bone ingrowth. The subdermal component includes a proximal portion that is adapted for attachment to the distal end of the stem, and a fixation surface that is adapted to promote soft tissue fixation. The percutaneous post has a proximal end that is adapted to be attached to the subdermal component.
