Manufacturer Narrative

Investigation ¿ evaluation: reviews of the complaint history, instructions for use (ifu), quality control, and specifications of the returned device were conducted during the investigation.The complaint device was not returned; therefore, no physical examinations could be performed.However, cook opened pr (b)(4) from pr (b)(4) (related issue with the same facility, same physicians, and same device), the returned device from (b)(4) will be used as a representative device for this investigation.That device evaluation is as follows: the visual inspection of the returned package confirmed that the entire vrs-6.0-90 device was returned used with extensive biological matter.The pin vise handle was separated from the cloversnare.The gray inner catheter had been withdrawn leaving the cloversnare inside the two coaxial blue sheaths.The dilator was also returned.The gray inner catheter could be easily advanced over the cloversnare wire into the inner sheath.The pin vise handle could be tightened securely onto the cloversnare wire.The inner and outer sheaths could not be separated.The hubs of the sheaths could be unscrewed, but the sheath tubings were stuck together at an unknown location.The distal end hole of the inner sheath was damaged, likely from the argon filter.The outer sheath¿s outer diameter was.156¿.Because they could not be separated, the coaxial sheath system was cut 33.1cm from the hub of the outer sheath.The proximal end of the inner sheath could be removed through the outer sheath.The distal end of the inner sheath could not be removed from the distal end of the outer sheath.The distal coaxial sheath system was again cut 22.9cm from the distal tip of the outer sheath.The proximal inner sheath could be easily removed from the proximal outer sheath.Pliers were used to remove the distal inner sheath from the distal out sheath.There was extensive dried biomatter between the sheaths.The cut portions of the inner sheath¿s outer diameter measured.125¿.There was a slight kink 2.5cm from the distal tip of the inner sheath, where the distal tip of the outer sheath aligned.When the most distal section of the inner sheath was reinserted into the most distal section of the outer sheath, there was no resistance.The outer sheath¿s distal tip accepted a.127¿ pin gauge with little resistance.Additionally, a document based investigation evaluation was performed.There is no evidence to suggest the product was not made to specifications.The lot number of the device is not known; accordingly, a review of the device history record could not be conducted.Furthermore, reviews of the specifications and quality control procedures were conducted, and no gaps were discovered.Moreover, an ifu is provided with this device stating all necessary warnings, precautions, indications, contraindications as well as step by step instructions on the use of the device.Based on the information provided and the examination of the returned product, investigation has concluded that a root cause for this event could not be established.We will continue our monitoring of similar complaints and have notified the appropriate personnel of this event.Per the quality engineering risk assessment no further action is required.This report is required by the fda under 21 cfr part 803.This report is based on unconfirmed information submitted by others.Neither the submission of this report nor any statement made in it is intended to be an admission that any cook device is defective or malfunctioned; that a death or serious injury occurred; or that any cook device caused or contributed to; or is likely to cause or contribute to a death or serious injury if a malfunction occurred.
