The subject invention provides devices and methods for alleviating discomfort associated with neuroma formation. The devices and methods of the invention effectively use the body's natural response of reconstructing implanted biomaterials to minimize the size of, isolate, and protect a neuroma. In preferred embodiments, the subject device is a cylindrical cap, wherein the internal chamber of the cylindrical cap physically partitions the nerve to enable an arrangement of nerve fibers (as opposed to haphazardly arranged nerve fibers often produced in neuromas). In addition, the cap's material remodels into a tissue cushion after implantation, which protects the neuroma from being stimulated and inducing pain.
