ABSTRACT:
A guidewire includes an elongate flexible unitary body with a plurality of spaced apart grooves in its outer surface and defining a tip support section. In one embodiment, the plurality of grooves take the form of a series of equally axially spaced apart transverse grooves which extend circumferentially around the outer surface of the elongate flexible body. A cross section of each groove may have a V-shape or U-shape, with each groove having rounded over opposing outer edges. A distal tip section is connected to the tip support section, and a main section is connected to the tip support section opposite the distal tip section. Preferably the main section, tip support section, and a portion of the distal tip section are formed of a unitary metal body or wire. The distal tip section also preferably includes a flattened wire portion surrounding by a wound coil.
