    摘要: Methods for producing a fibrin matrix comprising a fusion peptide are described herein. In some embodiments, the method includes providing three different components, including a first component containing fibrinogen or a fibrinogen precursor and optionally, transglutaminase or a transglutaminase precursor, a second component containing thrombin or a thrombin precursor, and a third component containing a fusion peptide. In these embodiments, neither the first component nor the second component includes the fusion peptide. In some embodiments, the first or second components are premixed with the third component. The first, second and third components are mixed to form a fibrin matrix comprising a covalently linked fusion peptide. The mixing is carried out in a time frame of not more than 5 days. A kit for producing the fibrin matrix comprising a covalently linked fusion peptide is also described herein.

    摘要: 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).

    摘要: The invention concerns a bone graft material for use in a spinal fusion method, wherein the material comprises i) a composition for forming a matrix, comprising at least a first matrix material precursor component and a second matrix material precursor component, capable of forming a matrix by crosslinking of the precursor components under appropriate conditions; and ii) a bioactive factor, which is biologically active to stimulate bone formation between two vertebrae, and for effecting or supporting spinal fusion; wherein the spinal fusion method comprises the steps of applying a cage in between the two vertebrae, which is not pre-filled with the bone graft material; and subsequently applying the bone graft material adjacent to and/or into the cage, such that essentially the entire remaining volume between the two vertebrae is filled with the bone graft material. The invention allows for ease of use while forming a more homogeneous matrix.

    摘要: Methods for making biomaterials for use as a tissue sealant, kits containing precursors for forming the biomaterials, and the resulting biomaterials are described herein. The biomaterials are formed from a composition comprising at least a first and a second precursor molecule, wherein: i) the first precursor molecule is a poly(ethylene glycol) based polymer having x nucleophilic groups selected from the group consisting of thiol or amino groups, wherein x is greater than or equal to 2 ii) the second precursor molecule is of the general formula: A-[(C3H6O)n—(C2H4O)m—B]i wherein m and n are integers from 1 to 200 i is greater than 2 A is a branch point B is a conjugated unsaturated group The precursors are selected based on the desired properties of the biomaterial. Optionally, the biomaterials contain additives, such as thixotropic agents, radiopaque agents, or bioactive agents. In the preferred embodiment, the biomaterials are used to reduce, inhibit, or contain loss of a biological fluid or gas in a patient.
