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.The following were reviewed as part of this investigation: patient severity, frequency analysis, applicable previous investigation(s), sample (if available), and applicable fmea documents.Based on a review of this information, the following was concluded: the complaint of a stuck guidewire was confirmed and the cause was determined to be use related.The product returned for evaluation was an 18ga x 2.75in introducer needle and a 0.038" 70cm guidewire.The investigation findings are consistent with damage caused by retraction of the guidewire against the bevel of the introducer needle.The returned product sample was evaluated and the guidewire was confirmed to be firmly lodged within the introducer needle and the core wire was broken.Microscopic examination of the needle/tip wire region revealed the damage to the inside edge of the introducer needle which can occur if the guidewire is forcefully retracted against the needle, damaging the shape of the sharpened bevel.Additionally, biological material was seen between the wire and needle which appeared to have contributed to the observed guidewire fracture as retraction of the wire together with the biological material could have caused the pieces to become stuck.The wire was then forced through the needle and dark red, hardened, fibrous, residue was observed to thickly coat the wire which confirmed the cause of the event.Normal movement of the guidewire is away from the sharpened bevel and will not damage the wire.If the guidewire direction is reversed, the guidewire is then pulled against the sharpened edge of the needle bevel and can cause shearing damage of the wire and/or cause the wire to become stuck within the needle.The product instruction for use (ifu) contains the following information which may be relevant to this type of event, "do not pull back standard guidewire over needle bevel as this could sever the end of the guidewire.The introducer needle must be removed first." an examination of the wire structure revealed no potential damage/defect related to manufacture of the product.A lot history review (lhr) of rebp1080 showed one other similar product complaints from this lot number.
