| 摘要 |
The invention relates to an arrangement for assessing the motility of a generally tubular anatomical organ ( 1 ), said arrangement comprising a longitudinally extending catheter ( 6 ) being adapted for introducing into said organ ( 1 ). The invention furthermore comprises an electrode arrangement ( 7 ) arranged along the longitudinal extension of said catheter ( 6 ), a detection unit ( 8 ) for measuring the electric potential (V(d)) at least partly along the length of said organ ( 1 ) and an evaluation unit ( 13 ) for detecting a generally step-like change ( 19 ) in the measured electric potential and determining the distance between a position along said catheter ( 6 ) corresponding to said step-like change ( 19 ) and a predetermined fixed point ( 16 ) to which the catheter ( 6 ) can be attached. The invention also relates to a method for such motility assessment. |
