Guide wire activation mechanism and proximal actuation mechanism

An intraluminal guide wire, comprising:

• a hollow elongated shaft extending between a distal end thereof and a proximal end thereof,
• a user actuation segment extending proximally from the proximal end of the hollow elongated shaft, the user actuation segment configured for movement relative to the hollow elongated shaft, and wherein the user actuation segment is connected to the hollow elongated shaft at an intersection;
• a core wire extending between the user actuation segment and a distal portion of the hollow elongated shaft;
• and
• an inner member having:
• a proximal end thereof positioned at least partially within and fixed relative to the user actuation segment;
• and
• a distal end thereof configured for placement at least partially within and for axial movement relative to the hollow elongated shaft, wherein the core wire passes through the inner member, and
• wherein the user actuation segment is configured to cause axial movement of the core wire relative to the hollow elongated shaft, resulting in a deflection or straightening of the distal portion of the hollow elongated shaft, and
• wherein the intersection comprises a stopper or detent configured to prevent proximal movement of the hollow elongated shaft with respect to the user actuation segment beyond a certain position where the intersection has a length.
