It was reported that during a cardiac ablation procedure, there was difficulty advancing the guidewire after introduction of the catheter through the sheath.Ablation was made but then 3/4 into the procedure, fibrous material was noted on the outside of the sheath.Intracardiac echocardiogram (ice) imaging was performed to check for any visual remnant in the left atrium, and none was observed.The sheath was removed, and a new sheath was prepped and introduced over a new guidewire.The case continued and the case was completed.No patient complications have been reported as a result of this event.

Product event summary: the 10fcc13 flexcath contour steerable sheath with lot 0012861820 and data files were returned and analyzed.An image file returned from the field was reviewed.The image showed the sheath delaminated string in the bag.Visual inspection before functional testing and dissection was performed on the shaft, handle, and dilator.No anomaly was identified during the external visual inspection.The handle, shaft, and sideport were intact with no apparent issue.Functional testing was performed and no anomaly was discovered.The steering mechanism and deflection tests were completed successfully.Primary deflection at 90° and 180°, as well as secondary deflection at 90°, were achieved without any issues.The mechanism operated smoothly, with no friction, resistance, or unusual noise.The performance test with sentinel blackbelt leak tester was performed.The pressure test with 45 psig showed the pressure decay in the device was 0.127 psig.The aspiration test with negative pressure of 8.5 psig showed the pressure decay in the device was 0.0123 psig.All the performance tests were in the acceptable range.The shaft, side tube, and valve were all leak-t ight with no apparent issue.Borescope inspection of the sheath revealed delamination of the ptfe sheath liner.In conclusion, the reported foreign material issue was observed during data analysis.The sheath failed the returned product inspection due to delamination of the ptfe sheath liner.Medtronic submits this report to comply with fda regulations 21 cfr parts 4 and 803.Medtronic has made reasonable efforts to provide as much relevant information as is available to the company as of the submission date of this report.This report does not constitute an admission or a conclusion by fda, medtronic, or its employees that the device, medtronic, or its employee caused or contributed to the event described in the report.Any required fields that are unpopulated are blank because the information is currently unknown or unavailable.Medtronic will submit a supplemental report if additional relevant information becomes known.
