Abstract
The catheter assembly employs a catheter unit, a needle unit and a guide wire unit which has a guide wire located within the hollow needle of the needle unit in the retracted position of the needle unit. The guide wire is initially spaced about three to six millimeters from the distal end of the hollow needle and can be inserted into a vessel over a distance of about one-half inch. The needle unit has a flashback chamber which is sealed by the guide wire unit to prevent outflow of blood.
