AI Technical Summary

Technical Problem

Existing methods for placing catheters, such as X-ray machines, are cumbersome, costly, and risky due to the proximity of anatomical regions like the esophagus and trachea, leading to potential harmful or fatal errors in catheter placement during digestive tract procedures.

Method used

A catheter guidance system with a stimulation electrode assembly and recording electrode assembly that delivers electrical stimulation and monitors tissue response to ensure correct placement within the digestive tract by using evoked potentials and impedance measurements, communicated in real-time to a processor for accurate placement verification.

Benefits of technology

This system allows for efficient, accurate, and safe placement of catheters within the digestive tract, reducing the risk of respiratory tract insertion and saving time and resources by providing immediate confirmation of correct placement.

Abstract

A tubing assembly is provided for use with an electronic catheter guidance system. This assembly includes a catheter, a stimulation electrode assembly, and an electrical connection for delivering a stimulation waveform to the electrode assembly. The catheter extends longitudinally and has a proximal and a distal end, defining a lumen between them. The catheter is configured for placement within the patient's digestive tract. The stimulation electrode assembly is configured to deliver an electrical stimulus to the tissue. A catheter guidance system and method are also provided for the precise placement of the catheter within the digestive tract.
