Complaint conclusion: the marker bands on a saber balloon catheter (4mm x 10cm x 150cm) were out of position.There was no patient injury reported.The device was clinically used.The device was not returned for analysis.A product history record (phr) review of lot 17709378 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.The reported ¿marker band-balloon catheters- offset/out of position - in-patient¿ could not be confirmed as the device was not returned for analysis.The exact cause could not be determined.With the paucity of information available and without the return of the product or films of the procedure, it is not possible to draw a clinical conclusion between the device and the event.However, vessel characteristics and procedural factors may have contributed to the reported event.According to the device description in the safety information in the instructions for use ¿the cordis saber percutaneous transluminal angioplasty (pta) dilatation catheter is a catheter with a distal inflatable balloon.Radiopaque marker bands indicate the dilating section of the balloon and aid in balloon placement.For balloon lengths greater than or equal to 100mm, the distal section will have one (1) marker band and proximal section will consist of two (2) adjacent marker bands.For balloon lengths less than 100mm, the distal and proximal section will have each one (1) marker band.The catheter tip is tapered to ease entry into peripheral arteries and to facilitate the crossing of tight stenoses.The radiopaque marker bands (the length between the outer edge of most proximal to the outer edge of most distal marker band) indicate the stated nominal length of the balloon.¿ neither the phr nor the information available suggests a design or manufacturing related cause for the reported event; therefore, no corrective/ preventive action will be taken at this time.
