Guidewires are essential endovascular tools designed for precise navigation and deployment of embolic coils in neurovascular, peripheral, and vascular occlusion procedures. These flexible, hydrophilic-coated micro-guidewires (0.014-0.021 inch diameter) feature a shaped distal tip, radiopaque markers, and steamable curves for atraumatic vessel selection and coil delivery through microcatheters. Constructed from nitinol or stainless steel cores with polymer jackets, they provide torque control, kink resistance, and lubricity to minimize vessel trauma during aneurysm coiling, AVM treatment, or tumor embolization. Steam shaping allows customization for complex anatomies, ensuring stable positioning and high procedural success rates in interventional radiology and neurosurgery.
