Abstract

The present invention provides a diagnostic device suitable for attachment to the external surface of an elongate medical instrument, such as an endoscope,comprising: a) an inner radially-expandable element located within the lumen of a separate, outer, radially-expandable element, wherein said outer expandable element is fitted with a plurality of RF electrodes on its outer surface; and b) a harness unit containing one or more conduits for connecting the lumen of the inner expandable element with a source of pressurized inflation fluid, together with electrical wiring that is capable of connecting said RF electrodes either directly or indirectly with external power, control and/or computational units.
