AI Technical Summary

Technical Problem

Current cardiovascular catheter procedures rely on standard curve shapes that often do not match individual patient anatomies, leading to difficulties in reaching target sites, increased procedure time, and decreased success rates, especially in patients with unique or extreme anatomies.

Method used

The method involves generating customized catheter shapes based on patient-specific anatomies using vasculature images, such as CT scans or ultrasound images, to determine a planned vascular pathway, which is then converted into three-dimensional shaping coordinates for a catheter shaping apparatus to reshape the catheter.

Benefits of technology

This approach allows for on-demand shaping of custom catheters that accurately match patient anatomies, reducing procedure time and improving success rates by enabling precise navigation to target sites.

Abstract

A method and apparatus are disclosed for generating custom cardiovascular catheter shapes based on individual patient anatomies. As such, on-demand shaping of custom catheters can be accomplished within the context of the cardiovascular catheter procedure. This can also allow for the re-shaping and use of existing catheters, even with patient populations having unique or extreme anatomies or having anatomies that are uncommon for the type of procedure being performed.
