Transdermal intraosseous device
First Claim
1. A method of implanting a transdermal intraosseous device for coupling an external prosthetic device to a bone stump, the method comprising:
- implanting a bone fixator in an intramedullary canal of the bone stump;
connecting subcutaneously a first component of a transdermal adapter to a distal portion of the bone fixator;
covering a dome-shaped portion of the first component with skin from the bone stump;
allowing the skin to heal over a porous layer of the dome-shaped portion; and
coupling transcutaneously a proximal portion of a second component of the transdermal adapter to the first component,wherein coupling transcutaneously the proximal portion of the second component of the transdermal adapter to the first component includes puncturing the healed skin and creating an opening for the second component.

Abstract
A transdermal intraosseous device for coupling a bone stump to an external prosthetic device includes a bone fixator, an external connector and a plurality of modular interface components. The bone fixator includes a proximal portion configured for anchoring into the bone stump of the patient and a distal portion including a base collar configured for subcutaneous implantation. The external connector has a distal portion for coupling to the external prosthetic device and a proximal portion for coupling to the distal portion of the bone fixator. Each interface component can be removably coupled to the base collar and has different size and shape to provide a surgeon-selected transition between the prosthetic device and the patient'"'"'s skin.

13. A method of implanting a transdermal intraosseous device for coupling an external prosthetic device to a bone stump, the method comprising:
-
implanting a bone fixator having a distal portion and a proximal portion in an intramedullary canal of the bone stump; connecting subcutaneously a first component of a transdermal adapter to the distal portion of the bone fixator; pre-stressing a compliant member receiving in a well of the distal portion of the bone fixator; covering a dome-shaped portion of the first component with skin from the bone stump; allowing the skin to heal over a porous layer of the dome-shaped portion; creating an opening in the healed skin over the dome-shaped portion; and coupling transcutaneously a proximal portion of a second component of the transdermal adapter to the first component. - View Dependent Claims (14, 15)
