ENDOSCOPIC MEASUREMENT OF MYOELECTRICAL ACTIVITY FROM INTRA-ABDOMINAL ORGANS

摘要

A catheter structure (10) includes an elongated tube structure (16) having distal and proximal ends and an axis. Electrodes (22) are associated with the tube structure (16) and are constructed and arranged to be moved from a retraced position substantially within the tube structure (16) to an extended position extended directly outwardly from the distal end (18) of the tube structure (16) and generally in the direction of the axis. The electrodes (22) are constructed and arranged to obtain signals relating to myoelectrical activity of an intra-abdominal organ. Actuating structure (34, 36) is operatively associated with the electrodes (22) to move the electrodes between the extended and retraced positions.
