USPTO Abstract
The present invention relates to novel nonpolymeric compounds and compositions that form liquid, high viscosity materials suitable for the delivery of biologically active substances in a controlled fashion, and for use as medical or surgical devices. The materials can optionally be diluted with a solvent to form a material of lower viscosity, rendering the material easy to administer. This solvent may be water insoluble or water soluble, where the water soluble solvent rapidly diffuses or migrates away from the material in vivo, leaving a higher viscosity liquid material.
