  • Plurisubstituted hydroxyapatite and the composite thereof with a natural and/or synthetic polymer, their preparation and uses thereof
    Patent number: 9327976
    Abstract: The present invention relates to a hydroxyapatite multi-substituted with, physiologically compatible ion species and to its biohybrid composite with a natural and/or synthetic polymer, which are useful in the preparation of a biomimetic bone substitute for treating bone tissue defects. Furthermore, the present invention relates to a method for their preparation and uses.
    Type: Grant

  • Intrinsically magnetic hydroxyapatite
    Patent number: 9327027
    Abstract: The present invention relates to hydroxyapatite doped with Fe2+ ions and Fe3+ ions which partially substitute the calcium ions in the crystal lattice. The hydroxyapatite is characterized by an intrinsic magnetism of 0.05 to 8 emu/g, measured by applying a magnetic field of 34 Oe, due to the presence of magnetic nano-domains in the crystal lattice of HA, given the limited amount of magnetic secondary phases present, less than about 3% by volume. The intrinsically magnetic hydroxyapatite can be loaded with biological substances selected in the group consisting of proteins, genes, stem cells, growth factors, vascularization factors, active substances and drugs, under the control of an external magnetic field, as a carrier and release agent for biological substances or drugs, as a contrast agent in diagnostics or for bone or osteocartilage regeneration.

  • Cartilaginous and osteochondral substitute comprising multilayer structure and use thereof
    Patent number: 9155818
    Abstract: The present invention relates to a multilayer structure (1) including a first upper layer (2) consisting of an organic matrix including collagen and at least a lower layer (3, 4, . . . 10) consisting of a composite matrix including hydroxylapatite and collagen. Furthermore, the present invention relates to a cartilaginous substitute including said multilayer structure (1) as well as an osteochondral substitute including said multilayer structure (1). Finally, the present invention relates to the use of said multilayer structure (1) for the preparation of said cartilaginous substitute and said osteochondral substitute for the treatment of cartilaginous defects and osteochondral defects or for the neo-formation of a cartilaginous tissue and/or a subchondral bone tissue.
