METHODS FOR POSITIONING AN ULTRASONIC CATHETER
First Claim
Patent Images
1. A method for positioning a catheter having an emitter in a body of a patient, the method comprising:
- passing the emitter into at least a portion of the body, the emitter being at a leading end of the catheter and including an ultrasonic transducer;
transmitting energy from the ultrasonic transducer through at least a portion of the body; and
detecting the energy with at least one sensor.

Abstract
An emitter may be disposed in a patient. Output from the emitter may be detected by a detector connected with the guide rod and by a detector connected with the tracheal tube. Alternatively, a detector may detect the output from an emitter connected with the guide rod and by an emitter connected with the tracheal tube. Emitter units may be ultrasonic transducers and emit ultrasonic energy. The detector may respond to ultrasonic energy.
