ABSTRACT:
A combination of a protective tube and guidewire straightener used to locate a guidewire into a patient for introducing a catheter into a patient's bloodvessel. The guidewire straightener has a flexible end that flexes inwardly to lock the guidewire in a fixed position within the protective tube. The protective tube has an opening so that the guidewire straightener can be rotated by the user to align the flexible end with the opening to allow the flexible end to be released outwardly to unlock the guidewire so that it can move within the protective tube. A further opening in the shape of an elongated slot is formed in the protective tube and which allows the user to move the guidewire to advance or retract the guidewire from the protective tube. The positioning of the components are such that a user, by the manipulation of only one hand, can unlock the guidewire from it's fixed position and advance it into the patient, leaving the user's other hand free to carry out other operations.
