Abstract
Disclosed is a system that includes pressure sensors to assist in monitoring pressure at a selected location. Pressure sensors may be applied to or incorporated into catheters and/or shunts positioned within a patient. A monitoring system may then receive signals from the pressure sensors to monitor pressure at the location over time.
Claims18
A system for monitoring pressure in a subject, comprising:
- an elongated instrument configured to be placed within the subject, the elongated instrument having an elongated wall that extends a distance from a first terminal end to a second terminal end, the elongated instrument defining a lumen along at least a portion of the distance, the elongated instrument further defining a passage into the lumen;
- a plurality of portals formed through the elongated wall along a selected length configured to allow a fluid to flow into the lumen from an external environment;
- and
- a pressure sensor integrated with the elongated instrument and configured to measure a pressure within the external environment at the plurality of portals along the selected length, wherein the pressure sensor is configured to provide a pressure signal based on the measurement of the pressure at the external environment.
