1. A pressure measurement system, comprising:
- a catheter;
a pressure lumen disposed in the catheter and coupled to a pressure source;
a compliant bladder disposed on the catheter, the compliant bladder being in communication with the pressure lumen;
a retention balloon positioned proximal to the compliant bladder and configured to anchor the catheter within a patient body;
a pressure sensor coupled to the pressure lumen and configured to receive a pressure signal from the compliant bladder via the pressure lumen; and
a controller configured to receive the pressure signal from the pressure sensor and to control the pressure source to fill the compliant bladder with a volume of gas.

Abstract
Methods and apparatus for measuring pressure in a patient are provided which may include any number of features. One feature is a pressure measurement system comprising a pressure source, a compliant bladder, a catheter in communication with the pressure source, pressure sensors, and a controller configured to determine a pressure within the compliant bladder. The pressure measurement system can inflate the compliant bladder with gas or air to determine a pressure within a patient. In one embodiment, the pressure measurement system measures pressure within a peritoneal cavity.
