<p>A medical guide wire (100) for assisting placement of a tube into a patient is provided. The guide wire comprises a first section (1), a mid-section (3) configured to be straightened from an original shape to a straightened shape, and a second section (5) configured to protrude out of the tube when the tube reaches the mid-section during placement. In the original shape the mid-section comprises at least one of a curve bend or a kink configured to indicate to the operator to stop feeding the first section into the patient and to discourage guide wire retention in the tube by allowing the second section to protrude out of the tube when the tube reaches the mid-section. In the straightened shape, the mid-section is configured to allow the tube to pass along the mid-section and into the patient.</p> |
