Abstract
An esophageal catheter device including a catheter with a balloon pressure sensor affixed to an exterior surface of the catheter, and a stylet assembly including a stylet for providing appropriate rigidity to the catheter to aid insertion in the esophagus and a port for removably mounting a pressure transducer.
Claims20
An esophageal catheter device comprising:
- a catheter including an open end and a closed end, the closed end for removably mounting one of a pressure transducer and removably receiving a stylet;
- a balloon affixed to an exterior surface of the catheter, the balloon useable as a pressure sensor;
- a balloon inflation lumen extending through the catheter in communication with the interior of the balloon through at least one aperture extending through the catheter;
- and
- a stylet assembly including a stylet for providing appropriate rigidity to the catheter to aid insertion into the esophagus and a port for removably mounting a pressure transducer.
2 more elements
A stylet assembly for an esophageal catheter device having a balloon affixed to an exterior surface of the catheter, the balloon useable as a pressure sensor;
- the stylet assembly comprising:
- a coupler;
- a stylet having an end affixed to the coupler;
- and
- a port extending from the coupler for removably mounting a pressure transducer.
2 more elements
A method for intra-thoracic pressure monitoring, the method comprising the steps of:
- providing an esophageal catheter device including a catheter, a balloon affixed to an exterior surface of the catheter, the balloon useable as a pressure sensor, a balloon inflation lumen extending through the catheter in communication with the interior of the balloon through at least one aperture extending through the catheter, and a stylet assembly including a stylet for providing appropriate rigidity to the catheter to aid insertion in the esophagus and a port for removably mounting a pressure transducer;
- mounting a pressure transducer to the port of the stylet assembly;
- inserting the catheter device into an esophagus;
- adding the correct amount of air to the sensor balloon;
- positioning the sensor balloon of the catheter device in a desired location in the esophagus using pressure information obtained through the sensor balloon, the stylet assembly and pressure transducer working in concert.
