A sheath for use with an interventional device for tissue spectroscopy within a body includes a substantially cylindrical, flexible body having an open proximal end and a closed distal end. The flexible body securely receives interventional device via an interference fit. At least the distal end of the flexible body is formed of a material substantially transmissive of at least one of ultraviolet or visible light. For example, the material can be a polymeric materials such as polyurethane, polyethylene or polystyrene. The sheath can be disposable.
