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.
Claims44
A process of making a medical material comprising forming an organogel around a powder of a water soluble biologic, with the powder being dispersed in the organogel.
A biomaterial for controlled release of a therapeutic water soluble biologic comprising a pharmaceutically acceptable xerogel that comprises solid particles of the biologic dispersed therein with the xerogel being a hydrogel when exposed to water.
A process of making a medical material comprising
- forming an organogel,
- making a xerogel from the organogel,
- and providing the xerogel as a collection of particles, wherein the xerogel is a hydrogel upon exposure to an aqueous solution.
