METHOD FOR CALIBRATING AN EXPANDABLE MEANS OF A MEDICAL DEVICE AND METHOD FOR MONITORING THE PRESSURE EXERTED BY THE INTERIOR WALL OF A BIOLOGICAL CHANNEL

摘要

The present invention relates to a method for determining the working pressure (PW) of an expandable means placed in the lumen of a biological channel of diameter (d) such that the expandable means exerts a maximum pressure (PMax) on the interior wall of the biological channel without causing damage to the tissues of the channel. The invention further provides a method for determining the contact pressure (PC) of an expandable means placed in the lumen of a biological channel such that the expandable means comes into full contact with the interior wall of the biological channel. The invention also provides a method for the real-time monitoring of the pressure exerted by the interior wall of a biological channel.
