Abstract
A device including an outer shell having a first longitudinal axis and a first arcuate shape. The outer shell is opaque to ultraviolet light and to visible light. The device also includes an inner shell having a second longitudinal axis. The inner shell is connected longitudinally to the outer shell along a first longitudinal length and a second longitudinal length. The inner shell has a second arcuate shape different than the first arcuate shape. A chamber is disposed between the outer shell and the inner shell. The chamber is defined by a difference between the first arcuate shape and the second arcuate shape. The device also includes an ultraviolet light source disposed along the second longitudinal axis.
