This device is used for therapeutic purposes.(b)(4) - no consequences or impact to patient.(b)(4).The product analysis found the following: condition upon receipt: 1 un-sealed sample, part number 1883672hs, from lot number hg05t32 received; there was evidence of biological contaminants [based off of the reactivity with hydrogen peroxide]¿ visually, the distal tip had broken off which would have resulted in the reported event.The portion that became detached measured 0.47¿.When viewed under magnification, the break point, the spiral wrap had turned in on itself in a clockwise direction indicating the device was turning clockwise when it broke and excess torsional load contributed to the breakage.The diamond grit at the tip was compacted with bone-like material and the inside diameter of outer tube near the break point was gouged which may indicate excess pressure was use during use however this cannot be confirmed.
