Arrangement and Method for Assessing the Motility of a Generally Tubular Anatomical Organ

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.
