Abstract
Serial-solvent biomaterials are described. Embodiments include materials made in an organic solvent that are stripped of the solvent and used in a patient, where they imbibe water and form a hydrogel. These materials are useful for, among other things, delivering therapeutic agents, tissue augmentation, and radiological marking.
Claims19
A process of making a medical material comprising forming an organogel around a powder of a water soluble biologic, with the organogel comprising an organic solvent and with the powder being dispersed in the organogel, wherein the organogel comprises covalently crosslinked hydrophilic polymers and/or ionically crosslinked polymers, wherein the organogel is formed in an absence of aqueous solution.
A process of making a medical material comprising
- forming an organogel around a powder of a water soluble biologic, with the organogel comprising an organic solvent and with the powder being dispersed in the organogel, wherein the organogel is formed in the absence of aqueous solution;
- and
- removing the organic solvent from the organogel to thereby form a xerogel.
