The device history records have been reviewed with special attention to the raw materials, subassemblies, manufacturing process, and quality control testing.This lot met all release criteria.There was nothing found to indicate there was a manufacturing related cause for this event.This is the only complaint reported to date for this lot number and failure mode.One maxcore biopsy needle was returned for evaluation.The investigation was confirmed for bent, as the sample notch was found to be bent.The investigation was also confirmed for material fragmentation, as skiving was noted on the sample notch.The investigation was inconclusive for the reported difficulty removing from the tissue, as the device could not be fully functionally tested due to the needle bend and the conditions of the reported event could not be replicated.Labeling review: the current ifu (instructions for use) states: warnings: note: if collecting multiple samples, inspect the needle for damaged point, bent shaft or other imperfections after each sample is collected.Do not use needle if any imperfection is noted.Precautions: never test the product by firing into the air.Damage may occur to the needle/cannula tip and could result in patient and/or user injury.Unusual force applied to the stylet or unusual resistance against the stylet while extended out of the supportive cannula may cause the stylet to bend at the specimen notch.A bent specimen notch may interfere with the needle function.Directions for use: bard max-core biopsy instrument preparation: before using, inspect the needle for damaged point, bent shaft or other imperfections that would prevent proper function.If the needle is damaged or bent, do not use.Energize (cock) instrument by pulling back on the top slide to withdraw the cannula and lock in place.Then pull back on the bottom slide to withdraw the stylet and lock in place.Remove protective needle sheath and yellow guard.Instrument is ready to fire when both slides are locked back.Recommendation: for ease of insertion, puncture the skin with a scalpel at the entry site.Biopsy procedure: verify instrument is energized (cocked).Insert tip of needle to the point to be biopsied.While maintaining instrument's position and the needle orientation, depress the rear actuator button, or push the side actuator forward (direction of arrow), to cause both stylet and cannula to automatically advance.Remove needle from patient and pull back on the top slide to withdraw the cannula and expose the biopsy specimen.Remove the specimen.If additional biopsies are required, pull back on the bottom slide to withdraw the stylet and repeat the procedure.
