Abstract
A guidewire for use in guiding a catheter has a tip construction that includes a core wire within a helical coil. The core wire has a distal tip segment that is tapered and is further impressed with a pair of opposed flattened surfaces extending along the taper, the surfaces lying at an angle to each other and defining a progressively flattened tip having increased width in a distal direction to define a duck-bill configuration. The tip construction provides improved column strength at the tip to resist guidewire prolapse while providing excellent torsional and flexibility characteristics.
