We missed a turn and hit a guide wire or something, I have no idea.

Catheters are inserted using a long guide wire and moved towards the heart.

Once in position the guide wire is then removed.

A small balloon is slid along the guide wire into the blocked artery.

Her guide wire was in position; the most delicate part of the procedure was over.

A guide wire is passed through the needle into the pelvis.

The needle is then withdrawn with the guide wire still inside the pelvis.

Gracefully, she spun and pulled herself along a guide wire to it.

A very thin guide wire is inside the catheter.

As supplied, the line has a guide wire inside.
