Dr. Luis Casavantes like most responsible healthcare professionals use disposable micro cannulas. With the threat of HIV and Hep C, it would be too great of a risk to use re-usable cannulas. I\'m not aware of any cannula that can endure the repeated stress of an autoclave machine.
It surprises me to see ANY medical professional using auto clavable instruments which penetrate any area of the body. You can auto clave all you like, but the fact is \"crud\" still accumulates inside of them.
