(b)(4).The actual device involved in the reported incident was not returned for evaluation.However, the facility did return a photo of the involved needle.Based on the photo, the tip of the spinal needle cannula appeared to be broken off.However, without the actual sample, a thorough sample analysis could not be performed and no specific conclusions can be drawn.The event description did indicate that the needle bent during insertion.While no specific conclusion can be drawn, incidents of this nature can generally occur when the needle is subjected to some type of trauma during use that stresses the device beyond its design capabilities.Review of the discrepancy management system database performed for the reported lot number did not reveal any abnormalities or nonconformances of this nature.No adverse quality trends of this nature were identified during the complaint review process for the reported catalog number or needle material number.There were no other reports of this nature against the reported lot number.All available information has been forwarded to the device manufacturer of the needle.If the physical sample is received or if additional pertinent information becomes available, a follow-up report will be filed.
