A personalized medical device intended for correction of defects, in particular in the orofacial area is multicomposite and comprises a hard tissue replacement and a soft tissue replacement. The hard tissue replacement is a hard core of biocompatible thermoplastic material and the soft tissue replacement is a biocompatible elastic substance. Preparation of personalized medical device even in the prenatal period using CT, MRI and 3D/4D electronic USG imaging and “additive manufacturing” technology.

The present disclosure provides synthetic collagen and methods of making and using synthetic collagen that include a synthetic collagen that facilitates wound closure comprising an isolated and purified triple helical backbone protein that facilitates wound closure comprising one or more alteration in a triple helical backbone protein sequence, that stabilize the isolated and purified triple helical backbone protein and does not disrupt an additional collagen ligand interaction; and one or more integrin binding motifs, wherein the isolated and purified triple helical backbone protein facilitates wound closure.

A tissue graft for soft tissue repair or reconstruction comprising a sheet of a biopolymer-based matrix having a plurality of small perforations and a plurality of large perforations. The small perforations are sized to facilitate clotting and granulation tissue development within the perforations which, in turn, facilitates revascularization and cell repopulation in the patient. The large perforations are sized to reduce the occurrence of clotting and granulation tissue development within the perforations so that extravascular tissue fluids accumulating at the implant site can drain through the tissue graft. The large perforations enhance mammal tissue anchoring by permitting mammal tissue to compress into the perforations increasing mammal tissue contact area.

Disclosed herein are a biodegradable polymer microparticle for a filler comprising a core and a shell, wherein the core contains secondary particles including aggregates of a plurality of primary particles, the shell has a raspberry shaped structure, an average particle diameter (D.sub.50) of the biodegradable polymer microparticle ranges from 20 to 200 μm, a manufacturing method thereof, a freeze-dried body including the same, and filler injection including the same.

The present invention generally relates to the use of small particles, such as micro particles or nanoparticles, to produce a therapeutic scar such as “trans-mural” scarring or other desired “deep tissue” scarring. In one preferred embodiment, these particles can be delivered to a target location by an implant. More specifically, these particles can be incorporated into the structure of implants or into the coatings on implants. In another preferred embodiment, these small particles can be delivered directly with a catheter by electrophoresis or hydraulic pressure.

The present disclosure relates to tissue matrix products. The products can includes tissue matrices that have holes or perforations located at certain positions to improve certain in vivo functions without substantial loss of strength or other important properties.

A synthetic construct suitable for implantation into a biological organism that includes at least one polymer scaffold; wherein the at least one polymer scaffold includes at least one layer of polymer fibers that have been deposited by electrospinning; wherein the orientation of the fibers in the at least one polymer scaffold relative to one another is generally parallel, random, or both; and wherein the at least one polymer scaffold has been adapted to function as at least one of a substantially two-dimensional implantable structure and a substantially three-dimensional implantable tubular structure.

Methods are described herein for facilitating tissue regeneration in humans and other large organisms, and kits therefor. Application of an inhibitor of focal adhesion kinase (FAK) to injured tissue may reduce fibrosis and/or scarring during the wound healing process. Patient care for a large number of fibrotic diseases which affect organ function may be ameliorated by such treatment. Kits for application of the FAK inhibitor may include a hydrogel formulation encapsulating the FAK inhibitor.

Disclosed is a patch or bandage for tissue regeneration and/or repair. The bandage comprises i) one or more proteins from the Wnt family, or an agonist of the Wnt signalling pathway; and ii) a scaffold, wherein the one or more Wnt proteins or Wnt agonist is immobilised on the scaffold, and wherein the scaffold is formed from a functionalised biocompatible polymer.

The invention relates to beads and a composition comprising an aqueous phase comprising a plurality of beads, the beads comprising or consisting in a hydrogel matrix comprising at least one carboxyalkyl chitosan having glucosamine units, N-acetyl-glucosamine units and glucosamine units substituted with a carboxyalkyl group, the carboxyalkyl chitosan being crosslinked by covalent bonds between the carboxyalkyl chitosan chains and/or co-crosslinked by covalent bonds with one or more other polymers.

The invention also relates to processes for their preparation and applications thereof.
