Abstract
Arthroscopic instrumentation for use in arthroscopic surgery and similar procedures. The instrumentation includes a cannula having a curved lumen and an elongated, flexible normally straight shape memory alloy probe. The probe is insertable into the lumen of the cannula, which in turn can be directed to a hard to reach operative site. The cannula causes the probe to bend as it passes the curves of the cannula, but the shape memory character of the probe causes the probe to exit the distal end of the cannula in a substantially straight orientation.
