AI Technical Summary

Technical Problem

Current medical devices, such as duodenoscopes, face challenges in accurately navigating instruments for procedures like ERCP due to limited visualization of bile duct trajectories and reliance on incomplete imaging information.

Method used

Incorporating a location tracking assembly with a magnetized elevator and magnetoresistive sensors to provide real-time positional and orientational feedback of the distal tip and elevator, enabling precise alignment and insertion of instruments.

Benefits of technology

This solution enhances the accuracy and safety of medical procedures by providing operators with real-time, three-dimensional views of instrument trajectories, reducing trauma to patients and minimizing complications like pancreatitis.

Abstract

The assembly of the medical device may include an elevator configured to raise and lower to adjust the orientation of an instrument inserted through a working channel of the medical device. The elevator may include a magnet. The assembly may also include a sensing element configured to measure the magnetic field of the magnet and output a signal indicative of a configuration of the elevator.
