Manufacturing review: a manufacturing review was conducted.The lot met all release criteria.Visual/microscopic inspection: the sample was returned.The core wire was intact.The distal tip was examined under microscopic magnification and material separation was observed.The outer catheter was examined under microscopic magnification and a partial circumferential tear was observed.No anomalies were noted to the transducer or saline hub, and no kinks were noted to the catheter.Functional/performance evaluation: the patency of the guidewire lumen was tested with an in-house guidewire and was unable to advance through the distal tip due to the partial circumferential tear.The device was attached without issue to the transducer of the in-house generator.Once connected to the in-house generator, an in-house device was used to flush the device with saline.The device was able to produce vibrations throughout the entire length of the catheter, and no unusual noises were heard.Misting was observed coming out from the distal tip, indicating that the device was vibrating properly.The distal tip of the catheter was pressed against one end of a 5mm plaster tile, and was able to penetrate the tile with no issues.No unusual noises were emitted from the catheter during functional testing.Medical records review: as medical records were not provided, a review could not be performed.Image/photo review: no medical images have been made available to the manufacturer.Conclusion: the device was returned.The investigation is unconfirmed for device inoperable as the device was able to activate and pass tile testing.The investigation is confirmed for material separation as the distal tip was separating from the outer catheter.The investigation is also confirmed for a tear as a partial circumferential tear was observed on the outer catheter.The definitive root cause could not be determined based upon available information.It is unknown whether procedural issues contributed to the event.Labeling review: the current ifu (instructions for use) states: warnings and precautions: - prior to use, the packaging and product should be inspected for signs of damage.Never use damaged product or product from a damaged package.Set up: - back the rigid portion of the catheter out of the end of the hoop, then carefully unsnap the catheter from the hoop with a gentle twisting motion interventional use: - slowly advance the catheter tip through the lesion.Apply steady, constant pressure so the tip of the catheter is engaged to the lesion.Upon successful recanalization of the lesion, advance the guidewire distal to the lesion and then withdraw the crosser 14p, 14s, or 18 catheter.(b)(4).The information provided by bard represents all of 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 bard.
