We have received the complaint device for evaluation and we have confirmed the reported incident.We observed the balloon had ruptured and the proximal ligature has slipped from its intended position.We did not observe any necking of the extrusion lumen.During the follow-up conversation with the contact person at the hospital, we learned that the device was not checked prior to the procedure.Surgeon had to pull the catheter to remove the undeflated balloon.While doing so, the balloon ruptured.Based on our investigation, it is possible that the balloon was not tied sufficiently to the catheter shaft.It is also possible that some anatomical (calcification or stenosis in the lesion area) or procedural factors (use of excessive force to remove the thrombus) may have contributed to the balloon failure.The arterial embolectomy catheter is not recommended for the removal of fibrous, adherent or calcified material (eg.Chronic clot, atherosclerotic plaque).This catheter is not designed to withstand the additional pull force needed to remove these materials.Based on this incident and similar incidents reported by other users, we are preparing to initiate a recall on certain lots of lemaitre 5 french plus over-the -wire embolectomy catheters.There was no injury to the patient as the result of this incident.
