Abstract
A microtube guide has a microtube combined with a free-floating and removable core. The microtube is generally hollow with a tube shaft and a distal ring, the tube shaft and the distal ring formed from flexible plastic. The distal ring is conformable to the core and straightenable for insertion into a patient's body, and deploys when the core is withdrawn to form a loop. The core is received by the microtube and is configured to advance into the distal ring to cause a diameter of the distal ring to expand, retract, or straighten. The distal ring diameter is thus adjustable by the user.
