Abstract
Method and apparatus for performing multidimensional pressure measurements by means of pressure profile sensors comprises using a multichannel catheter (7), each channel (1, 2 . . . ) of which is individually excited electrically, more particularly each channel is individually and distinctly excited electrically so to provide individual, distinct excitation signals for registration. Use for performing pressure measurements in various human or animal tracts like e.g. esophagus, urethra or intestine or various cavities like e.g. stomach, bladder or uterus.
