(b)(4).The customer returned one 4-l cvc for analysis.Signs of use in the form of biological material was observed inside the extension lines.Visual inspection of the catheter revealed both suture wings on the juncture hub are torn.The separation points appeared rough and jagged, which is consistent with undue force being applied to the wings when suturing the catheter.The separated suture wings would lead to separation of the catheter from the suture location , and therefore catheter migration.The catheter body total length measured 158 mm which is within the specification of 157mm - 177mm per catheter product drawing.A device history record review was performed and no relevant findings were identified.The instructions for use (ifu) provided with this kit informs the user, "use triangular juncture hub with side wings as primary suture site.Use catheter clamp and fastener as a secondary suture site as necessary".The ifu also states, "do not apply excessive force in placing or removing catheter or guidewire.Excessive force can cause component damage or breakage.If damage is suspected or withdrawal cannot be easily accomplished, radiographic visualization should be obtained and further consultation requested" the report of a catheter migration could not be fully confirmed by complaint investigation of the returned sample.Without a customer-supplied photo, there is insufficient evidence to confirm the migration of the catheter.However, visual inspection revealed both suture wings at the juncture hub were torn.This damage is consistent with undue force being applied to the suture wings, and the catheter migration is likely to have occurred as a result of the torn suture wings and loss of stabilization of the catheter at the suture site.The customer report indicated that the event occurred as "the patient was moved from the operating table and to his bed after the surgery" which likely contributed to the event.The catheter passed all relevant dimensional inspection, and a device history record review was performed with no relevant findings.Based on the sample returned and the customer report, unintentional use error likely caused or contributed to this event.Teleflex will continue to monitor and trend for complaints of this nature.
