Manufacturer Narrative

Device evaluation stated the following: the device was returned in three distinct pieces, 1) the deployment knob/line measuring approximately 100 cm long, 2) the body of the delivery catheter and 3) the partially deployed device secured to distal shaft of the delivery catheter.The distal knot row was examined under magnification.No abnormalities were noted that would prevent the knot rows from releasing from each other.Engineering used tweezers to pull on the broken deployment fibers and was able to successfully unfurl additional knot rows.The physician¿s observation that the deployment line broke halfway through deployment was confirmed.As no abnormalities were noted to prevent the knot rows from releasing from each other, the breaking of the deployment line is likely what prevented further deployment.It could not be determined with the available information why the deployment line broke.Not enough information was provided to determine the cause of the reported event.
