Additional Manufacturer Narrative
H11: manufacturing review: a manufacturing review was not requested because the lot is part of a larger capa investigation and situation analysis (sa).A voluntary field action has been initiated for venclose¿ rf ablation catheters.Software version 3.35 of the venclose¿ digirf¿ generator includes a self-check feature intended to identify internal wiring issues in venclose¿ rf ablation catheters.This check runs after the catheter is connected to the generator and before the procedure screen appears.If the catheter fails this check, the generator displays a ¿red x¿ without an error code, rendering the catheter unusable.Investigation summary: one venclose vcrf catheter60 cm was received for evaluation.The device was returned in a packaging hoop.The device appeared to have reside on the outer housing.A complete circumferential break was observed to the catheter proximal to the strain relief.A kink was observed to the catheter distal to the strain relief.A packaging hoop was returned with catheter.No visual damage was noted to the catheter coils.A complete circumferential break was noted on the catheter shaft, proximal to the strain relief.No wires were noted to protrude the break area.A kink was noted on the catheter shaft.Kink and break likely occurred due to the manner in which the device was packaged for return.Therefore, the kink and break are considered as incidental.Upon opening the handle, no damage was noted throughout.All wires were noted to be intact and in place.The proximal battery was noted to be partially seated within the battery holder.The distal battery was noted to be fully seated within the battery holder.Both battery holders were clean.When original batteries were removed, both battery and battery pads are clean.Under uv inspection, no glow anomalies were observed in both battery and pads in both samples.During functional testing, the catheter was plugged into the generator, as received with original batteries, and remained on the home screen (venclose logo).New batteries were inserted; catheter was plugged into generator with sd card.Brand all button was pressed and the generator screen displayed, catheter type already programmed.New batteries were inserted into generator without sd card and displayed error 53 (red x).Although an error 53 was displayed during the functional evaluation, the investigation is unconfirmed for nonstandard device and confirmed for red x - failed self-check.The red x was identified when a branding sd card was inserted the generator displayed ¿catheter type already programmed¿ with a random sequence of characters.When the self-check fails using software 3.35v, the generator screen will display a red x and the software will ¿corrupt¿ the catheter branding making the device unusable.If the catheter is unplugged and plugged back into the generator, error 53 will then be displayed as the branding is no longer valid.A flushing test was performed after unplugging catheter with an in-house syringe with water was attached to the male luer lock of the catheter.Three long and three short tests were completed successfully.No errors were presented.Therefore, based on findings, the investigation is determined to be unconfirmed for the identified error 53 and the investigation is determined to be confirmed for the reported red x issue displayed on screen.The definitive root cause for the reported red x cannot be determined and the root cause for the identified error 53 issue cannot be determined.Capa #11926759 was opened to address red x esds triple trigger complaints that were using v3.35 generator firmware.Labeling review: as the reported event did not allege a labeling or use related issue, a labeling review is not required.G3, h6 (method, result, conclusion).Section a through f ¿ the information provide by bd represents all the known information at this time.Despite good faith efforts to obtain additional information, the complainant/reporter was unable or unwilling to provide any further patient, product, or procedural details to bd.
