摘要:
A guidewire for use in ear, nose and throat procedures may include an elongate core wire having a proximal region and a distal region. The distal region of the core wire may include a flattened portion adapted to provide preferential flexure along at least one axis of the wire. The distal region of the core wire may include a tip portion distal of the flattened portion, where at least one cross-sectional dimension of the tip portion is greater than at least one cross-sectional dimension of the flattened portion. The guidewire may include an outer coil disposed around at least a portion of the elongate core wire. The guidewire may also include an atraumatic tip coupled to the core wire or the outer coil.
