Device for measuring body cavities and comprises catheter and non-stretchable measuring part with adequate circumferential dimension to establish contact with body cavity

摘要

The device comprises a catheter (1,2) and a non-stretchable measuring part with adequate circumferential dimension to establish contact with a body cavity. A pump (40) is connected to the catheter to inflate it to the extent that it fills out the body cavity without deforming the cavity. The catheter has at least two cavities separated by a longitudinal separation wall.
