Manufacturing review: the device history records have been reviewed with special attention to the subassemblies, material review reports, raw material testing, manufacturing process, and quality control inspection.This lot met all release criteria.There was nothing found to indicate there was a manufacturing related cause for this event.Visual/microscopic inspection: the sample was returned clean.Under microscopic magnification (20x) a portion of the guidewire was found to be uncoiled and was observed to be puncturing through the catheter 1.8cm from the distal tip.No other anomalies were noted along the length of the catheter.Functional/performance evaluation: the guidewire was retracted and the proximal end of the guidewire was used to test the patency of the guidewire lumen.The proximal end of the guidewire was loaded through the rapid exchange junction and exited the distal tip with no issues.The proximal end of the guidewire was then inserted through the distal tip of the catheter and it exited the rapid exchange junction with no issues.Medical records review: medical records were not provided; therefore, a review could not be performed.Image/photo review: images/photos were not provided; therefore, a review could not be performed.Conclusion: the sample was returned.The investigation was confirmed for device-device incompatibility and a puncture in the catheter, as a portion of the guidewire was found to be uncoiled and was puncturing through the catheter.The definitive root cause could not be determined based upon the available information.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; attach the irrigation system to the irrigation lumen on the proximal end of the crosser catheter; for the crosser catheters 14p, 14s, and 18 only, flush the guidewire lumen of the crosser catheter using a standard 10ml syringe with heparinized saline.Interventional use: load the crosser catheter 14p, 14s, or 18 over the wire and introduce through rhv.Take care not to damage the tip of the crosser catheter during introduction; no resistance should be encountered during this process; warning! use extra caution when loading the crosser catheter 18 over a.014¿ or a ¿docking¿ wire, as the significant mismatch in diameters may increase the likelihood of guidewire lumen piercing.(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.
