Manufacturer Narrative

This report is being submitted pursuant to the provisions of 21 cfr, part 803.This report may be based on information which has not been investigated or verified prior to the required reporting date.This report does not reflect a conclusion by biosense webster inc., or its employees that the report constitutes an admission that the product, biosense webster inc., or its employees caused or contributed to the potential event described in this report.If information is obtained that was not available for the initial report, a follow-up report will be filed as appropriate.If additional information is received regarding this event, a supplemental 3500a report will be submitted to the fda.Manufacturer's ref.# (b)(4).

Event Description

It was reported that a patient underwent an atrial fibrillation (afib) ¿ paroxysmal ablation procedure with a lassostar nav circular mapping catheter and internal components were exposed.It was reported that it was not possible to advance the lassostar nav circular mapping catheter through the heliostar (hs) catheter if the inflation knob was in the ¿deflated¿ mode so it was pressed to ¿inflate¿ to allow the lassostar nav circular mapping catheter pass and then pulled again to ¿deflate¿ to be able to enter into the guidestar.After the 3rd vein isolation the lassostar nav circular mapping catheter felt with bad maneuverability and was removed to inspect and noticed the plastic on the lasso was wrinkled and that a little metal needle part of a cable was exposed.The catheter was replaced.There was no patient consequence.The customer¿s reported issue of resistance with the sheath is not considered to be mdr reportable since an increased potential for patient injury is remote.This issue is reportable for the internal components exposed.

Manufacturer Narrative

On 27-apr-2023, the bwi product analysis lab received the complaint device for evaluation.The product analysis has begun but is not completed at this time.When the investigational analysis has been completed, a supplemental 3500a report will be submitted.If additional information is received regarding this event, a supplemental 3500a report will be submitted to the fda.Manufacturer's ref.# (b)(4).

Manufacturer Narrative
