During an acute myocardial infarction (ami), cardiogenic shock (cgs) procedure, a 23fr introducer sheath kinked when the physician was trying to push the sheath into the body under fluoro.A second 23fr sheath was used and it kinked at the same spot where the iliac looked calcified.The 23fr introducers were exchanged for a gore sheath.The patient passed away in the intensive care unit due to overall heart and organ failure, death not related to device.The patient had decompesated heart failure due to severe mitral regurgitation.On (b)(6) 2021 the customer confirmed device is a 23f, but the lot number is unknown.

The device was used in treatment.The device was not returned for analysis, therefore, the exact cause of the product issue cannot be determined and the clinical observation could not be confirmed.The lot number of the 23f abiomed introducer is unknown, however the following controls are in place to mitigate the reported product issue.Per procedure (abiomed introducer sheath in-process and final inspections): measure dimensions: measure tip i.D.Of sheath using appropriate pin gauges to be in range of 0.305" - 0.307" for 23f.Visual inspection: using 10x magnification, verify the tip is round, no flash protruding greater than 0.4 mm (0.016") and no flash with width (around circumference) greater than 0.7 mm (0.028"), no splitting, cracks or other damages.Visual inspection: with naked eye at a distance of 12" to 18", verify the assembled sheath matches the drawing.Ensure parts are free of kinks, cracks, splits, sinks, excessive flash, loose/embedded fm, or any other damages.Per ifu never advance or withdraw guidewire or sheath when resistance is met.Determine cause by fluoroscopy and take remedial action.When injecting or aspirating through the sheath, use the sideport only.Avoid subjecting the device to unusual stresses.When assembling the sheath and dilator, care must be taken to insert the dilator tip straight through the center of the valve membrane in order to prevent inadvertent puncturing of the membrane.No further follow-up is required.Based on the investigation, a capa is not required as findings did not identify a design, labeling or manufacturing non-conformity.In addition, there was no new failure mode identified and the risk remains acceptable.The event will be re-evaluated if additional information becomes available.Oscor will continue to monitor this event type and risk.
