Abstract
A flexible guidewire having a marker region at its distal end. The marker region is defined by spaced apart platinum bands attached to a reduced diameter portion of a guidewire core wire. A flexible spring overlies the marker region and is of a two-piece construction. A proximal end of the spring is constructed of stainless steel that has multiple spaced gaps to facilitate viewing of the platinum bands. A distal portion of the spring is constructed of platinum and is welded to a distal end of the core wire.
