Abstract
Abstract A wire guide comprising an elongate central core (11) and a coil (14) formed of radiopaque material which is positioned substantially concentrically with the elongate central core. The wire guide also comprises a polymer sleeve (12) which encloses the elongated central core. The guide wire further comprises a hydrophilic coating (13) which substantially encloses the polymer sleeve.
