  • Patent number: 8282912
    Abstract: Methods for making biomaterials for augmentation of soft and hard tissues, kits containing precursors for forming the biomaterials, and the resulting biomaterials are described herein. The biomaterials are formed from at least a first and a second precursor component. The first precursor component contains at least two nucleophilic groups, and the second precursor component contains at least two electrophilic groups. The nucleophilic and electrophilic groups of the first and second precursor components form covalent linkages with each other at physiological temperatures. The precursors are selected based on the desired properties of the biomaterial. In the preferred embodiment, the first precursor is a siloxane. Optionally, the biomaterials contain additives, such as thixotropic agents, radiopaque agents, or bioactive agents. In the preferred embodiment, the biomaterials are used to augment at least one vertebra of the spine (vertebroplasty).

  • Patent number: 8044172
    Abstract: Cell-occlusive membrane, obtainable by reaction of at least two precursors in the presence of water. The first precursor A comprises a core and n chains each having a conjugated unsaturated group or a conjugated unsaturated bond, and the second precursor B comprises a core and m chains each having a thiol group, wherein m is greater than or equal to 2, n is greater than or equal to 2, and m+n is greater than or equal to 5. The reaction forms a three dimensional network with crosslinking-points. The adjacent crosslinking-points are connected by a chain having less than 600 atoms.
