ABSTRACT:
A small diameter steerable guidewire with uniform flexibility in its distal region particularly well suited for PTCA use is provided. The guidewire has a diameter of less than 0.50 mm and is formed from an elongated substantially cylindrical main core wire with a distal cylindrical region of reduced diameter at the distal end of the core wire. A safety wire is attached to the distal end of the region of reduced diameter and a safety tip attached to the distal end of the safety wire and coil. The safety wire and coil may be formed of a radio opaque material so the position of the wire can be accurately determined when in use.
