1. A system for monitoring pressure in a subject, comprising:

  • an elongated instrument configured to be placed within the subject, having an elongated wall extending a distance from a first terminal end to a second terminal end and forming a lumen along at least a portion of the distance, the elongated instrument further including a passage into the lumen through the first terminal end, wherein the elongated wall includes a maximum cross-sectional dimension;

    a plurality of portals formed though the elongated wall configured to allow a fluid to flow into the lumen from an external environment;

    a pressure sensor integrated with the elongated instrument configured to measure a pressure within the external environment near the plurality of portals and transmit a pressure signal based on the measurement of the pressure, wherein the pressure sensor does not increase the maximum cross-sectional dimension greater than about 20%; and

    a monitoring system configured to receive the pressure signals and provide an output to a user based on the received pressure signals.
