Guidewire with Multi-Edge Profile for Enhanced Torque and Reduced Friction
Summary
USPTO published patent application US20260097187A1 for a guidewire with a multi-edge profile designed to improve torque transmission and reduce friction during intravascular navigation. The application includes helical configurations with discrete peaks and valleys, variable pitch sections, and polymer jackets with hydrophilic coatings. The system may include diagnostic catheters deliverable simultaneously with main catheters without additional support.
What changed
USPTO published patent application US20260097187A1 for a guidewire with a multi-edge profile configured to improve torque transmission and reduce frictional engagement during intravascular navigation. The guidewire features a square cross-section twisted into a helical structure with discrete peaks and valleys to minimize contact area with anatomical structures and catheter lumens, enhancing trackability and directional control. The system includes variable pitch sections, polymer jackets, and hydrophilic coatings to improve lubricity.
Medical device manufacturers and R&D teams focused on interventional vascular devices should review this publication for competitive intelligence. The disclosed innovations in multi-edge profile geometry and synergistic catheter drag reduction may influence future product development strategies in the guidewire and catheter space.

Abstract
A guidewire is disclosed that includes a multi-edge profile configured to improve torque transmission and reduce frictional engagement during intravascular navigation. In some embodiments, the multi-edge profile includes a square cross-section twisted into a helical structure. In some embodiments, the helical configuration creates discrete peaks and valleys that minimize contact area with surrounding anatomical structures and catheter lumens, enhancing trackability and directional control. The guidewire may include variable pitch sections, polymer jackets, and hydrophilic coatings to further improve lubricity. In some embodiments, a method includes using the guidewire in combination with one or more catheters having textured inner surfaces to synergistically reduce drag and facilitate navigation through tortuous anatomy. In some embodiments, the system includes a diagnostic catheter that can be delivered to a tortuous pathway simultaneously with the catheter without the need for additional support catheters.
