Manufacturer Narrative

The device in question is the marked spring tip guidewire, a 210cm long solid metal mandrel with a flexible, variable thread, spring attached to the proximal tip.The marked spring tip guidewire is a reusable instrument to be used in conjunction with american dilators and is compatible with key med, savary, eder puestow, and celestin esophageal dilator systems.A dhr/lhr, device history record/lot history record, review was not accomplished for the lot number was not available.Two (2) used devices were returned to conmed complaint center.It was unable to differentiate between the devices in the lab.Thus, one (1) used device was received under rec (b)(4) & other was received under rec (b)(4) the returned devices were examined together in the laboratory.The complaint device was observed to be bent at the proximal end of the spring.However, the solder joint between the spring tip & the wire was acceptable in the returned devices.The device was examined in the laboratory.Visual inspection found the device in poor condition in that the spring tip guidewire was bent at the proximal end of the distal tip.This device does not function as designed and intended.The laboratory was able to reproduce and/or verify the reported failure mode thus, this complaint is confirmed.It is highly unlikely that products were shipped to the customer in the current condition.In-process & quality control inspection are done on the product and this failure mode is highly detectable.100% of the devices undergo hand pull & proof load guidewire to spring tests to assure proper function.Furthermore, damaged devices are scrapped during production.Improper handling of the device after shipping from conmed facility to the end-user facility could cause this complaint.The proximal end of the spring is less flexible than the distal end of the spring thus, excess force applied on the device during guidewire insertion/retraction process could cause tip to bend.The ifu, instructions for use, indicates, "the guidewire should not be advanced if resistance is met without determining the cause and taking remedial action".The ifu also specifies, "remove the guidewire from packaging and carefully inspect it for any damage that may have occurred during transit or handling".Thus, a damaged device should be detectable prior to any patient use.The ifu also specifies, "avoid using excessive force on the wire and spring tip while cleaning.Do not bend to twist the spring tip as it may cause the soldered joints to deteriorate".Possible cause for this complaint could be device damage post production, during device cleaning, or, excessive force used by the end-user on insertion/retraction of the device from the endoscope.No manufacturing related defect was observed during the investigation; therefore, no corrective action is recommended at this time.Conmed corporation is considering this complaint closed.This complaint was reported for two (2) bent guidewires therefor this complaint is associated with the following medwatches: 3007305485-2014-00038 and 3007305485-2014-00039.
