摘要： Injectable radio-opaque compositions for tissue augmentation and in particular hard tissue augmentation, and kits and methods of using thereof are described herein. The injectable compositions form porous, biologically degradable, fibrin matrices. The compositions are formed from fibrinogen, thrombin or another agent that causes the fibrinogen to crosslink, and strontium salts. Optionally an iodinated contrast agent is further incorporated in the composition. In certain aspects, the compositions have substantially no exothermicity when forming the matrix and the resulting matrices exhibit mechanical properties typically seen in elastomers. Adequate radio-opacity is achieved through the incorporation of strontium salts in combination or not with iodinated contrast agents.
摘要翻译：本文描述了用于组织增加，特别是硬组织增加的注射不透射线组合物，以及其使用的试剂盒及其使用方法。可注射组合物形成多孔，生物可降解的纤维蛋白基质。组合物由纤维蛋白原，凝血酶或引起纤维蛋白原交联的其它试剂和锶盐形成。任选地，将碘化造影剂进一步掺入组合物中。在某些方面，组合物在形成基质时基本上不具有放热性，并且所得基体表现出通常在弹性体中看到的机械性能。通过将锶盐与碘化造影剂组合或不结合来实现充分的无线电透明度。

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).
