A guidewire having a centrally located core wire about which is mounted a single outer helical coil spring. The core wire is typically longer than the outer helical coil spring, with the helical coil spring and core wire having common distal ends. The spring is brazed at both its distal and proximal end to the core wire. The distal brazing of the core wire and helical coil springs is rounded. A second small radiopaque helical coil spring is fitted in the distal end of the outer helical coil spring and may be brazed to the core wire and outer helical coil spring.
