The apparatus comprises an instrument having a flexible cable and an applicator suitable for use with a IN gastroscope, which can be deployed within a patient to delivery energy in a targeted or otherwise controllable manner. The applicator can deliver microwave energy by radiation. The direct and depth-limited nature of microwave energy can be make it more effective than ei ----. treatments that rely on thermal conduction. The applicator may include a radially extendable portion arranged to move an microwave IN energy delivery structure into contact with duodenal mucosal tissue at the treatment region. The applicator may comprise any of a © balloon, bipolar radiator, movable paddle, and rotatable roller element. ei C [Continued on next page] WO 2017/207531 A3 MIDEDIMOMOI DEEM 011111111111111 1011 OM 011111110111100# (88) Date publication of of the international search report: 04 January 2018 (04.01.2018)
