Patent ID: 8257435

Claim:
A skin integrated device comprising: an inner portion adapted to be positioned inside a bone of a human body; an outer portion adapted to be positioned outside the human body to receive a prosthesis; and a middle portion between the inner portion and the outer portion, adapted to be positioned at a skin layer of the human body, the inner portion, the outer portion, and the middle portion aligned in an elongate direction along a longitudinal axis, the middle portion comprising a porous permeable body comprising: a load-bearing frame comprising a network of solid members, at least one of the solid members extending in the elongate direction parallel to the longitudinal axis, and having at least one bore extending entirely through a width of the solid member in a direction transverse to the elongate direction, the frame adapted to carry body weight, forces, and moments associated with locomotion, and compacted and sintered particles filling in regions within the network between the solid members and around the solid members; wherein, in the middle portion: a volume fraction of the compacted and sintered particles is within a range of about 20% to about 100% of the total volume of the middle portion, the porosity of the volume fraction of the compacted and sintered particles is within a range of about 30% to about 50%; the compacted and sintered particles have a particle size within a range of 20 to 500 microns; and a pore size between the compacted and sintered particles is in a range of about 20 to about 350 microns.
