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 esophagus (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 esophagus (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 esophagus (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 method for producing a catheter (100) having a plurality of axially spaced apart electrodes (5) towards a distal end (4) of the catheter (100) comprises forming the electrodes (5) from a single sheet (110) of electrically conductive foil material by forming spaced apart slots (111) in the sheet material to define a plurality of spaced apart electrically conductive elements (114) extending transversely between spaced apart elongated connecting portion (112,113). The electrically conductive elements (114) subsequently form the electrodes (5), and are retained spaced apart by the connecting portions (112,113) until bonded to the catheter (100). Electrically conductive wires (10) electrically coupled to the electrically conductive elements (114) extend through an elongated slot (105) into and along an axial communicating bore (9) to a proximal end (3) of the catheter (100). Two pieces of double-sided adhesive tape (118) bonded to the electrically conductive elements (114) in turn bond the electrically conductive elements (114) to the catheter (100). After entering the wires (10) into the axial communicating bore (9) the electrically conductive elements (114) with the double-sided tape (118) are wrapped around the catheter (100) and are severed from the connecting portions (112,113). Free ends (115) of the electrically conductive elements (114) abut each other to form the electrodes (5) as band electrodes.

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).
