Device to promote drug-induced nerve regeneration

摘要

The invention relates generally to a system for promoting regeneration of a damaged nerve. In particular, the invention comprises: (1) a guide tube constructed to be attached to the damaged nerve; (2) guiding filaments disposed within the guide tube; and, (3) a therapeutic composition enclosed by the guide tube. Both the guide tube and the guiding filaments are composed of biologically compatible materials, while the therapeutic composition contains a nerve-growth-stimulating agent dispersed in a matrix-forming material. During treatment, the guide tube is inserted between the ends of lesioned nerves, resulting in the stimulation of axon growth.
