Abstract:
A removable sheath for providing repeated use of an interventional device for tissue spectroscopy in a mammalian body orifice having a contour, the sheath comprising:a flexible body having an open proximal end and a closed distal end, said flexible body being sized and shaped to receive the interventional device and to be removed from the device, said flexible body being conformable to the contour of the orifice, the distal end of the flexible body comprising a window that is substantially transmissive of an ultraviolet light; 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, wherein the fluid chamber receives a fluid through the channel to facilitate optical contact between the sheath and a tissue under examination.
