Abstract:
A guidewire (10) having a centrally located core wire (12) about which is mounted a single outer helical coil spring (14). The core wire (12) is typically longer than the outer helical coil spring (14), with the helical coil spring and core wire having common distal ends (20, 22). The spring (14) is brazed at both its distal and proximal end to the core wire (12). The distal brazing of the core wire (12) and helical coil springs (14) is rounded. A second small radiopaque helical coil spring (42) is fitted in the distal end of the outer helical coil spring (14) and brazed to the core wire (12) and outer helical coil spring (14) at a location proximal the helical coil spring distal end.
