1. A catheter configured to be inserted into a cavity of a patient for monitoring pressure, the catheter comprising:
a first lumen having a wall and at least one side opening in the wall configured for drainage from the cavity;
a second lumen;
an expandable first balloon at a distal portion of the catheter, the second lumen communicating with the first balloon, the first balloon having a distal portion and a first outer wall, the first balloon receiving fluid to move from a first condition to a more expanded condition, in the first condition, the balloon having the distal portion protruding distally of the catheter to cover a tip of the catheter and a proximal portion within the catheter, and upon expansion of the first balloon, the first balloon exits a distal opening of the catheter and expands radially distally of the distal opening, the first balloon having a fluid containing chamber configured to monitor pressure within the cavity of the patient as pressure on the first outer wall of the first balloon deforms the first balloon and compresses the fluid within the first balloon; and
a pressure sensor communicating with the fluid containing chamber for measuring pressure based on compression of the fluid caused by deformation of the first balloon resulting from deformation of the first balloon.
