1. An interventional device for tissue spectroscopy comprising:
- a probe insertible in an orifice of a body, the probe having a distal end and a proximal end and comprising a tissue spectroscopy apparatus positioned near the distal end, the tissue spectroscopy apparatus comprising a light source for illuminating tissue under examination with an ultraviolet light and a light detector for detecting an optical property of the illuminated tissue; and
a removable sheath for encapsulating the probe, the removable sheath comprising a flexible body having an open proximal end for receiving the probe and a closed distal end, a fluid chamber located at the distal end of the flexible body, and a channel extending from the proximal end to the distal end of the flexible body for providing fluid to the fluid chamber for optimizing optical contact between the interventional device and the tissue under examination, wherein at least the distal end of the flexible body is substantially transmissive of the ultraviolet light.

Abstract
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.
