A composite resin comprising silver nanoparticles and a polymer where the silver nanoparticles are formed by reduction of silver ions by the functional groups of the polymer without the addition or application of an external reducing agent. The composite resin has a low silver leach rate. The composite resin may be used as a surface coating, particularly an antimicrobial or antifouling surface coating.

A proto-device for implantation into soft tissue comprises an oblong device body, biodegradable microfibres adhesively attached to the body, a rigid matrix of biocompatible material enclosing the body and the microfibres. The biocompatible material is dissolvable and/or degradable in aqueous body fluid at a rate substantially superior to the rate of microfibre degradation. The proto-device is one of proto-microelectrode, proto-optical fibre, proto-polymer tube for drug delivery, proto-electrical lead, proto-encapsulated electronics. Also disclosed are uses of the proto-device and methods for its implantation and manufacture.

The disclosure relates to methods of making an osteoconductive polymer article for use as an orthopedic implant comprises steps of forming an article from a biocompatible, non-biodegradable polymer, the article comprising a non-flat surface with roughness Ra of at least 5 m; providing a dispersion of bioactive ceramic particles of particle size at most 10 m in a first solvent comprising a solvent for the polymer; coating at least the non-flat surface with the dispersion in at least one step; and rinsing the coated article with a second solvent being a non-solvent for the polymer to substantially remove the first solvent. Further disclosed is an osteoconductive polymer article for use as an orthopedic implant, which article is made from a biocompatible, non-biodegradable polymer and comprises a non-flat surface with roughness Ra of at least 5 m, wherein bioactive ceramic particles of particle size at most 10 m are partly embedded in the polymer at the surface of the article. The methods exhibit benefits in ease of modifying a surface layer with bioactive particles, applying mild conditions and not requiring use of further additives or post-treatments, or without significantly affecting bulk polymer properties, and result in an orthopedic implant article having particles adhering to the surface while still being accessible for interaction with surrounding tissue or fluid.

A process of forming a coated textile includes culturing human cells on a fiber of a textile such that the human cells produce and deposit human extracellular matrix (hECM) on the textile. The process also includes removing the human cells from the hECM to provide the coated textile of the textile and a coating comprising a residual of the hECM produced and deposited by the human cells on the textile during the culturing. A coated textile includes a textile and a coating on the textile. The coating includes hECM in a cell-deposited state in the coating. A solid-state bioreactor composition includes a poly(glycerol sebacate) (PGS) adduct. The PGS adduct includes PGS and a promoting factor or a promoting factor precursor. Another method includes implanting a coated textile in a human. The coated textile is an autograft. The coating includes hECM deposited by human cells from the human.

The present invention relates to large scale manufacture of nanoscale microsheets for use in applications such as wound healing or modification of a biological or medical surface.

A biodegradable in vivo supporting device is disclosed. In one embodiment, a coated stent device includes a biodegradable metal alloy scaffold made from a magnesium alloy, iron alloy, zinc alloy, or combination thereof, and the metal scaffold comprises a plurality of metal struts. The metal struts are at least partially covered with a biodegradable polymer coating. The biodegradable scaffold includes a radio-opaque marker made of a substance that blocks radiation. A cavity is manufactured in the scaffold and the radio-opaque marker is accommodated by the cavity.

The present disclosure describes a dental implant with functional gradient and respective obtention method, wherein the implant comprises an inner part of metal or metal alloy or titanium-based metal matrix composite which comprises on its surface a transition zone of rugose texture or surface pattern; an outer part composed of a ceramic or zirconia-based ceramic composite, and a diffusion protective film between the transition zone and the outer part described as an oxide and/or nitride protective film.

The present invention provides compositions for extended release of an active ingredient, comprising a lipid-saturated matrix formed from a biodegradable polymer. The present invention also provides methods of producing the matrix compositions and methods for using the matrix compositions to provide controlled release of an active ingredient in the body of a subject in need thereof.
