Guidewire with varying surface roughness and groove
A recently granted patent (Publication Number: US11969564B2) discloses a novel guidewire design comprising a core shaft, a coil body covering a distal end portion of the core shaft, and a coating agent on the outer periphery of the coil body. The unique feature of this guidewire is the presence of a distal coil body and a proximal coil body, with a groove formed along the longitudinal direction of the wire in the proximal coil body but not in the distal coil body. Additionally, the surface roughness of the proximal coil body is higher than that of the distal coil body, and the outer diameter of the proximal coil body with the coating agent is greater than that of the distal coil body with the coating agent.
Furthermore, the patent claims detail variations in the design, such as the presence of multiple grooves on the surface of the proximal coil body, the shape of the wire in the coil bodies (rectangular or circular), differences in coating agent thickness between the proximal and distal coil bodies, and variations in hardness. These features aim to enhance the performance and functionality of the guidewire in medical procedures where precise navigation and flexibility are crucial. The patent highlights the importance of surface characteristics and dimensions in optimizing the guidewire's effectiveness in medical applications, showcasing advancements in medical device technology.
