    摘要: 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).

    摘要: A system (1) and a device (3) is used in a fundoplication procedure in order to avoid over-tightening of the fundus of the stomach when the fundus is being wrapped around the oesophagus (7) adjacent the lower oesophageal sphincter (5). The device (3) comprises a catheter (8) having a primary balloon (12) located at a distal end (9) thereof which is inflatable with a saline solution by a primary pump (26). A pair of spaced apart primary stimulating electrodes (32) on the catheter (8) within the primary balloon (12) receive a stimulating current signal from a constant current signal generator (40) under the control of a microprocessor (43), which reads voltage signals from spaced apart primary receiving electrodes (35) on the catheter (8) in the balloon (12). The microprocessor (43) determines the diameter of the primary balloon (12) at locations adjacent the primary receiving electrodes (35), and an image (47) of the inflated primary balloon (12) is displayed on a visual display screen (48) along with corresponding diameter values of the primary balloon (12). The primary balloon (12) is located in the sphincter (5) and inflated with the saline solution until the sphincter (5) has been dilated to a desired diameter, which is observed on the visual display screen (45). As the fundus of the stomach is being wrapped around the oesophagus (7) adjacent the sphincter (5) the diameter of the primary balloon (12) is observed so that the fundus is not over-tightened. A secondary balloon (50) on the catheter (8) is independently inflatable for simulating a bolus of food in the oesophagus (7) so that the dilating response of the sphincter (5) can be determined by observing the image (47) of the primary balloon (12) and the diameter values thereof on the visual display screen (45).

    摘要: A balloon catheter comprising a catheter (3) and a balloon (7) located at a distal end (5) of the catheter (3). A plurality of measuring electrodes (12) formed on a primary substrate (17) extend around the catheter (3) within the balloon (7). The primary substrate (17) is formed by a portion of a flexible resilient membrane (25) which also forms a secondary substrate (19). The measuring electrodes (12) are formed on the primary substrate (17) by first electrically conductive tracks (27) and second electrically conductive tracks (28) which are electrically connected to the first electrically conductive tracks (27) are simultaneously formed on the secondary substrate (19). The membrane (25) is coiled to form a roll, and the primary substrate (17) is also coiled around the rolled secondary substrate (19). The coiled primary and secondary substrates (17,19) is urged through a second lumen (20) in the catheter (3) from the proximal end (4) thereof to a radial slot (21) in the catheter communicating with the second lumen (20). The primary substrate (17) is urged through the radial slot (20) and wrapped around and bonded to the catheter (3) to form the measuring electrodes (12) as band electrodes.
