  • Publication number: 20220088270
    Abstract: The invention relates to methods for producing a polymeric scaffold for use in tissue engineering applications or soft tissue surgery, as well as to the produced scaffolds and an associated kit. The method features a first fast drying step of applying a mechanical compression on a polymeric gel layer and a second slow drying step of the gel up to reach a polymer mass fraction of at least 60% w/w in the final scaffold. The method allows the production of scaffolds with high regeneration and healing properties of a grafted tissue via host cell invasion and colonization, and a good suturability. These goals are achieved through the formation within the scaffold of a non-uniform architecture creating softer and stiffer areas, which is maintained even upon re-swelling of the scaffold upon hydration of the final dried product.

  • Patent number: 10758492
    Abstract: The present invention relates to polymeric structures, in the form of flat membrane-like surfaces or micro- nanostruc-tures such as capsules, characterized in that it comprises a substantially two-dimensional layer of covalently-bonded monomers of R-substituted metal or metalloid oxides. Said polymeric structures in most embodiments have a crystal architecture with a hexagonal lattice, but the nature of the covalent bonds present therein impart a bending flexibility that make the polymeric structures behave as a “soft” crystal. Methods of producing such structures, composition comprising thereof and method of using thereof are also included within the present disclosure.

  • Publication number: 20190060522
    Abstract: The invention relates to a scaffold material comprising a carrier and embedded microbeads for use in tissue engineering applications such as soft tissues therapeutic treatment. The scaffold provides a short-term bulking effect coupled with a long-term functional activity. Both the carrier and the microbeads are substantially composed of natural or extracellular matrix-derived polymers, and the beads can comprise homogeneously distributed active agents, providing a regulated agent release along time. An aspect of the invention relates to a method for producing the microbeads of the invention by using an expressly designed microfluidic chip.

  • Publication number: 20100291215
    Abstract: Bioactive molecules are entrapped within a matrix for the controlled delivery of these compounds for therapeutic healing applications. The matrix may be formed of natural or synthetic compounds. The primary method of entrapment of the bioactive molecule is through precipitation of the bioactive molecule during gelation of the matrix, either in vitro or in vivo. The bioactive molecule may be modified to reduce its effective solubility in the matrix to retain it more effectively within the matrix, such as through the deglycosylation of members within the cystine knot growth factor superfamily and particularly within the TGF? superfamily. The matrix may be modified to include sites with binding affinity for different bioactive molecules, for example, for heparin binding.

  • Publication number: 20090004238
    Abstract: Methods of applying biocompatible coating materials around biological materials using photopolymerization while maintaining the pre-encapsulation status of the biological materials are disclosed. The coatings can be placed directly onto the surface of the biological materials or onto the surface of other coating materials that hold the biological materials. The components of the polymerization reactions that produce the coatings can include natural and synthetic polymers, macromers, accelerants, cocatalysts, photoinitiators, and radiation. Methods of utilizing these encapsulated biological materials to treat different human and animal diseases or disorders by implanting them into several areas in the body including the subcutaneous site are also disclosed.
