The present invention relates to hydroxyapatite doped with Feions and Feions 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.

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.

Plurisubstituted hydroxyapatite and the composite thereof with a natural and/or synthetic polymer, their preparation and uses thereof

The present invention relates to a multilayer structure () including a first upper layer () consisting of an organic matrix including collagen and at least a lower layer () consisting of a composite matrix including hydroxylapatite and collagen. Furthermore, the present invention relates to a cartilaginous substitute including said multilayer structure () as well as an osteochondral substitute including said multilayer structure (). Finally, the present invention relates to the use of said multilayer structure () 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.

A method for perfusing a biocompatible material graft with a perfusion liquid includes the steps of: introducing the graft () in a perfusion chamber (), arranging a transfer chamber () partly filled with the perfusion liquid (), coupling in a tight manner the perfusion chamber () and the transfer chamber () for establishing a fluid communication between them, lowering the pressure in the transfer chamber () for transferring therein part of the air existing in the perfusion chamber (), increasing the pressure within the transfer chamber () for injecting in the perfusion chamber () the perfusion liquid () existing in the transfer chamber (). A perfusion kit includes a perfusion chamber () apt to contain a graft () to be perfused with a liquid () and a transfer chamber () apt to contain a liquid () to be perfused, the perfusion chamber () being connectable in a tight manner with the transfer chamber () for allowing a fluid exchange between the two chambers () and inhibiting a fluid exchange between the two chambers () and the external environment.

The object of the present invention is a process for obtaining a bone substitute of given chemical and physical characteristics and entirely similar to those of the mineral portion of natural bone tissue. The process substitutes Ca ions with Mg ions in a porous matrix; the process comprises a phase of contacting the matrix with a saline aqueous solution containing an effective quantity of Mg ions at a pressure greater than or equal to 1 bar.
