(b)(4).The actual device involved in the reported incident was not returned for evaluation.Without the actual sample or lot number, a thorough sample analysis or batch record review could not be performed and no specific conclusions can be drawn.While no specific conclusions can be drawn, incidents of shredded / broken catheters can occur when a catheter becomes lodged between rigid body structures and is stretched beyond its design capabilities; or if the catheter is withdrawn or partially withdrawn through the needle, thereby shearing the catheter.Per the instructions for use (ifu) for the reported product catalog number, "caution: do not withdraw catheter through needle because of the possible danger of shearing." no adverse quality trends of this nature were identified during the complaint review process for the reported catalog number or involved catheter material number.If additional pertinent information becomes available or if the physical sample is received for evaluation, a follow-up report will be filed.
