摘要：
A steerable guide wire includes a core wire having a proximal end and a distal end. A braided filament is affixed to the distal end of the core wire. An outer coil surrounds at least a portion of the core wire and the braided filament. A proximal end of the braided filament is secured to a distal end of the coil. By locating the braided filament in the distal tip portion of the guide wire, a guide wire is provided that is highly flexible, has a high degree of tensile integrity, and is highly steerable, even in tortuous vasculature. Filter and balloon catheters having braided filaments at the distal end are also described.
