A guidewire suited for inserting both diagnostic and therapeutic catheters. The guidewire has an initial uniform diameter segment that is coated with Telfon along a majority of its length. This core station tapers along a uniform portion to a second constant diameter segment surrounded by a flexible spring tip. The core again tapers in a region where the flexible spring separates from the core. The core is then flattened to increase flexibility within the flexible spring and the flattened core and spring are brazed together at a extreme distal tip portion to form a hemispherical distal guidewire tip.
