Hydrophilic Guidewire
The composition of Hydrophilic Coated Guidewires typically consists of a core material, such as stainless steel or nitinol, surrounded by a hydrophilic polymer coating. Stainless steel provides the necessary rigidity and structural integrity to the guidewire, enabling it to withstand the forces encountered during navigation through the body. On the other hand, nitinol, a shape-memory alloy, offers flexibility and elasticity, allowing the guidewire to adapt to the contours of anatomical structures without sacrificing durability.
The hydrophilic coating, usually composed of PTFE or a similar material, serves as a lubricious layer that reduces friction and enhances the guidewire’s ability to glide smoothly through the vasculature or other bodily passages. This coating undergoes a specialized manufacturing process to ensure uniformity and durability, enabling the guidewire to maintain its hydrophilic properties throughout the duration of the procedure.
