AI Technical Summary

Technical Problem

Balancing the stiffness and flexibility of intraluminal imaging devices, such as IVUS catheters, is challenging, particularly in navigating tortuous vasculature without kinking, which complicates advancement through human vasculature.

Method used

A reinforcement layer is coupled to a distal portion of the flexible elongate member, transitioning its stiffness to resist kinking and allow navigation through tighter turns, comprising a polymer with a different hardness than the flexible member.

Benefits of technology

The reinforcement layer increases column strength, enabling the device to bend without kinking and maintain pushability for effective advancement through vasculature.
