1. A catheter insertable into a cavity of a patient for monitoring pressure without injecting fluid within the cavity, the catheter comprising:
an outer flexible tube;
a first balloon at a distal portion of the catheter, the first balloon having a first outer wall exposed within the body cavity and receiving fluid therein to move from a first condition to a more expanded condition, the first balloon expanding radially outwardly with respect to the catheter and providing continuity with a wall of the cavity;
a first lumen within the outer tube communicating with the first balloon forming a passage for fluid to move the first balloon to a more expanded position;
a gas containing chamber; and
a second lumen within the outer tube for draining the cavity, the second lumen in dependent of and radially spaced from the first lumen;
a side hole in communication with the second lumen, the side hole axially spaced from the first balloon;
wherein the first balloon in the more expanded position is deformable based on compression of gas caused by deformation of the expanded first balloon, and the deformation of the first balloon provides pressure capable of being measured at multiple times during a procedure without injecting fluid within the body cavity;
wherein the catheter is configured for connection at a proximal portion to a pressure measurement device.
