Esophageal balloon catheter device
First Claim
Patent Images
1. 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.

14. 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. - View Dependent Claims (15, 16, 17, 18, 19, 20)
