Based on the finding of the product analysis, the product malfunction code of catheter/body/shaft-burst in patient is being added.As reported, during the intra-arterial chemotherapy procedure the radiopaque tip of the 100 cm.4 fr.Tempo jb 1 diagnostic catheter detached from the catheter.There was no reported patient injury. additional information received indicated that the reported product issue was that during manipulation of the catheter internally to the patient the guidewire pierced a catheter structure and exited sideways.There was no reported patient injury.The patient¿s hospitalization was not prolonged.No piece of the product fell into the patient.One non-sterile unit of cath tempo 4f jb 1 100cm was received coiled inside a plastic bag.Per visual analysis a rupture was found on the catheter tip at 2.3cm from catheter distal end.The ruptured catheter body was sent to sem analysis.Results showed that the analyzed material presents evidence of material deformation and elongations that suggest the application of a force by an unknown object from the inside to the outside of the catheter body that induced the material deformations and the rupture observed.No other anomalies were found during sem analysis.The inner diameter/outer diameter were measured near to tip rupture condition and results were found within specification.A device history record (dhr) review of the manufacturing documentation associated with lot 17445517 revealed no anomalies during the manufacturing and inspection processes that can be associated with the reported complaint.The complaint reported by the customer as ¿brite tip/distal tip - separated-in patient¿ was not confirmed since the catheter tip was not received separated.Instead of distal tip separation, a ¿catheter (body/shaft) ¿ burst¿ was found on the catheter tip area.The cause of the catheter tip damaged/ruptured condition found could not be conclusively determined during the analysis.Based on the limited information available for review, procedural/handling factors may have contributed to this issue reported as evidenced by the material deformation and elongations.As stated in the instructions for use (ifu), ¿to prevent damage to the catheter tip during removal from the package, grasp the hub and withdraw the catheter.Exercise care when removing guidewires from multiple-curve catheters.¿ neither the dhr review nor the product analysis suggest that the conditions reported are related to the manufacturing process of the unit.Therefore, no corrective and preventive actions will be taken at this time.
