Manufacturer Narrative

There are four needles and associated sutures remaining in the device handle.There are no outstanding damages to the device.Only small light dings on the outer edges of the threads were found.The male hex head is undamaged and the mating female hex driver is undamaged.Stripping in these areas would be a reason a driver shaft and anchor would turn independently.The other reason would be that the sutures gained slack from approaching and then backing off during insertion.This can disengage the hexes from each other allowing rotation of the handle but not the anchor.The device was tested in simulated bone material model.The driver shaft and anchor rotated simultaneously.The anchor rooted itself flush.No root cause related to the manufacture of this device can be determined for the stated complaint.Device returned for evaluation device evaluated by the manufacturer evaluation codes updated.
