Abstract
A system (1) for dilating an occlusion (3) in an oesophagus (4) comprises a device (5) having a catheter (8) extending from a proximal end (9) to a distal end (10). An inflatable balloon (12) defining a hollow interior region (14) is located on the catheter (8) adjacent the distal end (10) thereof for dilating the occlusion (3). The balloon (12) is inflated with a saline solution by a pump (34) through an axial communicating bore (20) and radial communicating bores (21) in the catheter (8). A pair of stimulating electrodes (25) on the catheter (8) within the balloon (12) adjacent axially opposite ends (18,19) thereof receive stimulating voltage signals from a signal generator (43). Receiving electrodes (28) on the catheter (8) between the stimulating electrodes (25) produce resulting voltage signals in response to the stimulating current signal on the stimulating electrodes (25) which are indicative of the transverse cross-sectional area of the balloon (12) adjacent the receiving electrodes (28) when the balloon (12) is inflated with the saline solution. A microprocessor (35) determines the diameter of the balloon (12) at the receiving electrodes (28) from the resulting signals thereon, and displays a three-dimensional image (46) of the balloon (12) on a visual display screen (47) as well as the corresponding diameter values in windows (48) on the visual display screen (47). A surgeon observes an image of the balloon (12) which corresponds to an image of the occlusion (3) and adjacent portion of the oesophagus (4) during dilating of the occlusion (3).
