Abstract
Official abstract text for this publication.
The present invention provides, among other things, implants including a biocompatible substrate, wherein the substrate includes a plurality of pores, such as trabecular and/or dodecahedral pores, and wherein said implant is configured as a transcutaneous implant. In some embodiments, provided implants may comprise multiple layers with differing pore densities, geometries, and/or distributions.
First claim
Opening claim text (preview).
We claim: 1. An implant comprising a biocompatible substrate including a first layer and a second layer, wherein said first layer comprises a plurality of pores, and said second layer comprises a plurality of pores, wherein the pores of said first layer have geometries that are different than the pores of said second layer, and wherein said implant is configured as a transcutaneous implant to remain in the skin and to facilitate skin tissue and/or subcutaneous tissue ingrowth. 2. The implant of claim 1 , wherein the pores of said first layer are regular and/or substantially uniform in at least one of size and shape. 3. The implant of claim 2 , wherein said regular and/or substantially uniform pores are dodecahedral. 4. The implant of claim 1 , wherein the pores of said second layer are regular and/or substantially uniform in at least one of size and shape. 5. The implant of claim 1 , wherein the pores of said first layer are irregular. 6. The implant of claim 1 , wherein the pores of said second layer are irregular. 7. The implant of claim 6 , wherein said irregular pores exhibit a trabecular or substantially trabecular geometry. 8. The implant of claim 1 , wherein said pores of said first layer are between 1-5,000 μm in diameter. 9. The implant of claim 1 , wherein said pores of said second layer are between 1-5,000 μm in diameter. 10. The implant of claim 1 , wherein the substrate comprises titanium, tantalum, a polymer, or a ceramic material. 11. The implant of claim 1 , wherein the substrate is coated with one or more growth factors.
