| 摘要 |
The invention relates to an arrangement for determining the degree of muscular contraction of a generally tubular anatomical organ ( 4 ), said arrangement comprising a longitudinally extending catheter ( 9 ) being adapted for introducing into said organ ( 4 ), and a measuring unit ( 11; 12 ) for cooperating with said catheter ( 9 ) and being adapted for assessing said degree of contraction. According to the intention, said catheter ( 9 ) is provided with a sensor arrangement ( 10; 22; 25 ) for indicating the geometrical configuration of said catheter ( 9 ), and said measuring unit ( 11; 12 ) is provided with means for determining the degree of longitudinal muscular contraction of said organ ( 4 ) based on values indicating said geometrical configuration. The invention also relates to a catheter for of generally longitudinal extension and being adapted for introducing into a generally tubular anatomical organ. The invention also relates to a method for assessing the degree of said muscular contraction. |
