A severed nerve may be surgically rejoined and severed axons fused via sequential administrations of solutions. The solutions may include a priming solution comprising methylene blue in a Ca.sup.2+-free saline solution, a fusion solution comprising about 50% (w/w) PEG, and a sealing solution comprising Ca.sup.2+-containing saline. The PEG fusion solution may be applied in a nerve treatment device configured to isolate the injured segment of the nerve. The device may include a containment chamber for creating a fluid containment field around the anastomosis. The device may have slits, slots, and/or apertures in opposing endwalls of the device designed to receive the nerve. The device may have an open bath configuration or may include separable lower and upper bodies to create a closed bath configuration. The device may include one or more fluid ports in fluid communication with the containment chamber for introducing and/or removing fluid.

A layered drug delivery device which includes a polymeric tissue interface layer and a polymeric backing layer. The polymeric tissue interface layer includes at least one ther-apeutic agent.
