  • Publication number: 20160101214
    Abstract: The present invention relates to a minimally-invasive method for restoring a damaged or degenerated intevertebral disc at an early stage. The method comprises the step of administering an injectable in situ setting formulation in the nucleus pulposus of the damaged or degenerated disc of the patient. The formulation once injected combines with nucleus matters and host cells, and becomes viscous or gels in situ within the annulus fibrosus of the disc for increasing the thickness and volume of the damaged or degenerated disc. The formulation is retained within the disc for providing restoration of the damaged or degenerated disc.

  • Patent number: 8920842
    Abstract: The present invention relates a biopolymeric liquid aqueous composition for producing self-gelling systems and gels, which comprises: an acidic water-based medium, 0.1 to 10% by weight of a pH-gelling acid-soluble biopolymer; and 0.1 to 10% by weight of a water-soluble molecule having a basic character and a pKa between 6.0 and 8.4, or a water-soluble residue or sequence of the molecule having a basic character and a pKa between 6.0 and 8.4. The liquid composition has a final pH ranging from 5.8 and 7.4, and forms a stable solid and homogeneous gel within a temperature range from 10 to 70° C.

  • Patent number: 8784850
    Abstract: The present disclosure relates to a chitosan solution neutralized with amino-sugar carbonate buffering solution or amino-sugar phosphate buffering solution or phosphorylated aminosugar buffering solution. The resulting thermogelling chitosan composition is highly biocompatible, isotonic and has the ability to rapidly turn into gel upon heating to the body temperature. It provides a novel chitosan-based composition to suitable for drug delivery, cell delivery and repair or regeneration of tissues and organs as well as other clinical treatment.

  • Patent number: 8747899
    Abstract: Self-forming hybrid compositions consisting in admixed liquid and solid components enable the formation of bio-materials. The present invention proposes a) a thermo-sensitive self-forming liquid component, being water-based and containing at least a polycationic polymer such as chitosan, and an organic mono-phosphate source, which is a solution at a pH ranging from 6.5 to 7.4; b) a solid component being mineral and composed of at least one of calcium, fluoride, strontium, carbonate and phosphate salts. Solid mineral salts preferentially have a recognized bioactive potential such as the calcium phosphate salts for bones. Both solid and liquid components are admixed to form an injectable liquid slurry or pre-gelled paste that turn in situ into a hybrid uniform gel-like bio-material.

  • Publication number: 20090202430
    Abstract: The present invention provides compositions and methods for tissue repair using a cytocompatible self-gelling cross-linked hydrogel. The composition comprises a biocompatible mixture of chitosan, bifunctional dialdehyde, and hydroxylated polymer, which can be used to immobilize or encapsulate viable cells, or bioactive substances. The method includes the process of mixing bioactive substances, live cells, and/or extracellular matrix components with a cross-linking solution comprising a bifunctional aldehyde-treated hydroxylated polymer such as hydroxyethyl cellulose. The cross-linking solution is then mixed homogenously with a neutral isotonic chitosan solution. The chitosan becomes cross-linked by the bifunctional aldehyde, while the cells are protected from potentially nocive effects of the aldehyde cross-linker by the hydroxylated polymer. The injectable solution retains cell viability and bioactivity, and immobilizes cells at the site of injection or delivery.
