Abstract
A guidewire can include a shaft or core wire that has a distal section configured for access to a vascular treatment site and a proximal section configured for intervention at a vascular treatment site. At least a portion of the distal section of the shaft or core wire can have a diameter that is greater than a diameter of the proximal section.
