Event Description

It was reported that a patient underwent an atrial fibrillation (afib) paroxysmal ablation procedure with a lassostar nav circular mapping catheter and the electrodes and the material covering the tip of the lasso were damaged as they exited the balloon lumen.It was impossible to assemble the lassostar nav until it came out of the heliostar balloon during preparation before introducing it into the patient.They found that there was resistance on both when fitting it into the balloon and when removing it.The electrodes and the material covering the tip of the lasso were damaged as they exited the balloon lumen.There was no patient consequence.

Manufacturer Narrative

It was reported that a patient underwent an atrial fibrillation (afib) ¿ paroxysmal ablation procedure with a lassostar nav circular mapping catheter and the electrodes and the material covering the tip of the lasso were damaged as they exited the balloon lumen.It was impossible to assemble the lassostar nav until it came out of the heliostar balloon during preparation before introducing it into the patient.They found that there was resistance on both when fitting it into the balloon and when removing it.The electrodes and the material covering the tip of the lasso were damaged as they exited the balloon lumen.There was no patient consequence.Device evaluation details: the device was returned to biosense webster (bwi) for evaluation.Visual inspection, and dimensional inspection of the returned device were performed following biosense webster inc.(bwi) procedures.Visual analysis revealed that the lassostar loop was observed broken and deformed, leaving wires exposed.The customer reported that there was resistance when inserting the lassostar catheter into the heliostar balloon, which could be a potential cause of the damage in the loop; however, this cannot be conclusively determined.A dimensional test was performed, and the outer diameters of the shaft, tip and, transitions were measured and found within specifications.The outer diameters of the rings could not be measured due to the damage on the loop a manufacturing record evaluation was performed for the finished device number lot 31090688l and no internal action related to the complaint was found during the review.Additionally, the manufacture and expiration dates have been provided.Therefore, fields d4.Expiration date and h4.Device manufacture date have been populated.The electrode damage issue reported by the customer was confirmed and this could be related to the resistance reported.The instructions for use contain the following recommendation: if a lassostar¿ catheter is used with the heliostar¿ catheter, do not extend the heliostar¿ catheter beyond the sheath tip until the lassostar¿ catheter has been fully advanced out of the guidewire lumen.In addition, do not use excessive force to advance or withdraw the catheter if resistance is encountered.As part of biosense webster's quality process, all devices are manufactured, inspected, and released to approved specifications.This product issue will be addressed through bwi's quality system.If additional information is received regarding this event, a supplemental 3500a report will be submitted to the fda.Manufacturer's reference number: (b)(4).
