Various embodiments disclosed relate to curable calcium phosphate compositions for use with porous structures and methods of using the same. In various embodiments, the present invention provides a curable calcium phosphate composition or a cured product thereof, with the curable calcium phosphate composition including calcium phosphate and a perfusion modifier. In various embodiments, the present invention provides an apparatus comprising a porous structure at least partially in contact with the curable calcium phosphate composition or a cured product thereof. The porous structure can include a porous substrate including a plurality of ligaments that define pores of the porous substrate, and a biocompatible metal coating on the plurality of ligaments of the porous substrate.

Compositions of small molecules, matrices, and isolated cells including methods of preparation, and methods for differentiation, trans-differentiation, and proliferation of animal cells into the osteoblast blast cell lineage were described. Examples of osteogenic materials that were administered to cells or co-cultured with cells are represented by compounds of Formula II, IV, and VI independently or preferably in combination with a matrix to afford bone cells. Small molecule-stimulated cells were also combined with a matrix, placed with a cellular adhesive or material carrier and implanted to a site in an animal for bone repair. Matrix pretreated with compounds of Formula II, IV, and VI were also used to cause cells to migrate to the matrix that is of use for therapeutic purposes.

The object of the present disclosure is to achieve a composite of dentin collagen obtained from human teeth and a growth factor with function of inducing bone growth, thereby improving a regeneration speed of alveolar bone. The present disclosure provides a method for manufacturing a bone graft composite, said method comprising: pulverizing a tooth to generate tooth powder, and washing and degreasing the tooth powder; demineralizing the degreased tooth powder so as to obtain dentin collagen; preparing a growth factor which includes a component to induce bone growth; and synthesizing a composite by mixing the obtained dentin collagen and growth factor.

Nerve scaffolds are described that include a tubular outer housing fabricated from a biocompatible polymer, within which are disposed a plurality of carbon nanofiber yarns. The carbon nanofiber yarns, which can be separated by distances roughly corresponding to an average nerve fiber diameter, provide surfaces on which nerve fibers can regrow. Because the proximate carbon nanofiber yarns can support individual nerve fibers, a nerve can be regenerated with a reduced likelihood of undesirable outcomes, such as nerve pain or reduced nerve function.

Implantable medical devices are provided. In one embodiment, a device includes a body having an external surface defining an outer profile of the device. The body includes a porous matrix including a series of interconnected macropores defined by a plurality of interconnected struts each including a hollow interior. A filler material substantially fills at least a portion of the series of interconnected macropores. The external surface of the body includes a plurality of openings communicating with the hollow interior of at least a portion of the plurality of interconnected struts. In a further aspect of this embodiment, the external surface includes exposed areas of the filler material and porous matrix in addition to the exposed openings. In another aspect, the porous matrix is formed from a bioresorbable ceramic and the filler material is a biologically stable polymeric material. Still, other aspects related to this and other embodiments are also disclosed.

The object of the invention is a porous alumina ceramic matrix grafted with an antibiotic, in particular vancoymicin, as well as its use in therapy. The invention also relates to a prosthesis or an implant using this matrix. The invention also relates to a method for preparing a matrix according to the invention.

The invention relates to a biocompatible molded part for supporting new bone formation, in particular the reformation of a jaw bone or a jaw bone portion in a mammal, preferably a human, wherein the molded part is suitable to be placed on the jaw bone and is designed as a solid body. The invention also relates to a composition for producing a biocompatible molded part, a method for producing a biocompatible molded part, a use of a biocompatible molded part and a kit comprising a plurality of molded parts.

Provided is a compression resistant implant configured to fit at or near a bone defect to promote bone growth. The compression resistant implant comprises a biodegradable polymer in an amount of about 0.1 wt % to about 20 wt % of the implant and a freeze-dried oxysterol in an amount of about 5 wt % to about 90 wt % of the implant. Methods of making and use are further provided.

A method of treating a bacterial infection including bacteria that have become resistant to an antibiotic in a subject in need thereof is provided. The method includes administering to the subject a safe and therapeutically effective amount of the antibiotic and a reviving agent selected from the group consisting of glass-ceramic particles, silver ions, and combinations thereof. The reviving agent restores antibiotic activity to the antibiotic against the bacteria.

Disclosed is an implanted device, comprising a device base body and an active drug, wherein the device base body is pure zinc and/or a zinc alloy, the zinc content in the device base body is 0.1-100%, and the active drug comprises anti-allergic drugs. After the implantation of the implanted device into the human body, the surrounding tissues of the implant would not have a clear hypersensitive reaction due to the presence of the anti-allergic drugs, and the implanted device can be used to be implanted into the body for supporting organ chambers, to fill the hollow chambers of the organs and tissues or as orthopaedic implants etc.
