As no sample was returned, angiodynamics was unable to perform a device evaluation.However, based on samples returned for similar complaints from this reporting customer, the reported complaint description of catheter fracture is confirmed.Angiodynamics had received three (3) smartports.One with no catheter tubing (labeled as sample #1) and 2 ports with catheter tubing (samples #2 and #3).There was no distinction between the port samples returned and the multiple complaint files opened based on the customer's reported occurrences, so the complaint samples were assigned a sample number and complaint file number, and investigated individually.A medwatch has been created for each complaint file.A visual inspection of sample returned with tubing was performed using magnification.As received, the catheter tubing was fractured.The customer's reported complaint description of "catheter fractured" is confirmed, as the samples were returned with the catheter tubing fractured.The catheters exhibited a crushing fatigue failure of the catheter tubing.This, along with the location of the fracture being 4-6cm from the port body indicate "pinch-off" syndrome as likely root cause for the catheter fracture.Although the complaint description is confirmed, a definitive root cause for the reported complaint description cannot be determined.A potential root cause of this failure is "pinch off syndrome".The directions for use supplied with the device instructs the physician/clinician on how to properly implant the catheter/port, and cautions against certain handling techniques to avoid "pinch-off syndrome".A review of the device history records was performed for the indicated packaging and component lots for any deviations related to the reported defect of the complaint.The review confirms that the lots met all material, assembly and performance specifications.The instructions for use, which is supplied to the user with this catalog number, contains the following statements: potential complications: catheter fragmentation and catheter pinch-off.Catheter placement considerations: warning: avoid medial catheter placement into subclavian vein through percutaneous technique.This placement could lead to catheter occlusion, damage, rupture, shearing, or fragmentation due to compression of the catheter between the first rib and clavicle.Catheter shearing has been reported when the catheter is inserted via a more medial route in the subclavian vein.Pinch-off syndrome: pinch-off syndrome signs may include difficulty in aspirating blood, resistance to flushing or infusion of medications or fluids that improves with position changes, infraclavicular pain and/or swelling with catheter flushing or infusion palpitations, sudden onset chest pain, cardiac arrhythmias, extra heart sound, chest wall swelling at the port pocket, vein insertion site, pain in shoulder or port area not associated with swelling, cough, paresthesia of arm on side of catheter withdrawal occlusion or swishing sound with catheter flushing.Warning: avoid medial catheter placement into subclavian vein through percutaneous technique.This placement could lead to catheter occlusion, damage, rupture, shearing, or fragmentation due to compression of the catheter between the first rib and clavicle.Catheter shearing has been reported when the catheter is inserted via a more medial route in the subclavian vein.Note: if infusion or aspiration is successful upon lifting arm above the head and turning the head, consider pinch-off syndrome as a possible cause.The line should be radiologically evaluated if pinch-off syndrome is suspected.A review of the angiodynamics complaint system noted no adverse trends for this complaint type and product family.This type of complaint will continue to be monitored for trends.Complaint reference (b)(4).
