Claim 0:
1. A method for measuring pressure within a body cavity of an anatomical region without insertion of fluid into the body cavity, the method comprising the steps of:
a. providing a catheter having an inner balloon and an outer balloon, a wall of the inner balloon spaced from a wall of the outer balloon, the inner balloon having a first region to receive balloon expanding fluid from the outer balloon on the first region;
b. inserting the catheter into the body cavity;
c. expanding the inner balloon from a first condition to a more inflated condition, an internal space of the inner balloon forming a gas containing chamber for containing a gas;
d. either before or after step (c), expanding the outer balloon from a first condition to a more inflated condition via insertion of the balloon expanding fluid; and
e. obtaining multiple pressure readings within the body cavity during a procedure based on deformation of the outer balloon which causes deformation of the inner balloon to monitor pressure of the anatomical region, the outer balloon providing a medium for transfer of the balloon expanding fluid against the wall of the inner balloon for multiple pressure measurements of the anatomical region without requiring insertion of fluid into the body cavity;
wherein the fluid is water and the body cavity is a bladder of a patient, and the catheter measures abdominal pressure via measurement of bladder pressure without filling the bladder with water.
