Manufacturer Narrative

Five units of the same model of langston were returned for evaluation per site request.Four of the units were unused/unopen and one was the damaged device used in the case.A manufacturing record review was completed and zero related nonconformances were found, therefore supporting the device met material, assembly and performance specifications prior to shipment.The unused units were inspected and no defects or nonconformances were present.The unit returned from the case was evaluated.The inner catheter lumen was separated about 3" from the distal tip.There was a kink on the inner lumen shaft just proximal of the separation point.Whitening of the pebax at the separation point confirms stretching of the material prior to separation.There was a kink on the inner lumen shaft just proximal of the separation point.Whitening of the pebax at the separation point confirms stretching of the material prior to separation.It is likely that the catheter lumen was weakened due to the kink and when the doctor tried to push the wire through the weakened section of the langston it tore the pebax material leading to the separation.

Event Description

Dr.Performed langston introduction as usual through the right radial access point.Anatomy was tortuous in this patient, but not out of the ordinary for this approach.Jwire and tig were used to cross the valve.The tig came out, leaving just the wire.The langston was introduced over the wire.The wire was removed.Transducer measurements were taken.The wire was reintroduced into langston for removal.The wire stopped/would not advance all the way into the langston.On the image is was observed the langston had bent/kinked at one of the curved areas - the distal subclavian artery.The wire could not be advanced past the bent portion, even with some manipulation techniques.Eventually when the wire was attempted to be pushed through it caused separation of the tip of the langston at the bend point.In order to retrieve the detached langston tip (about 3.5" in length) a new access point was created in the groin with an 8f sheath.A snare was used through this access site to successfully retrieve the detached tip.
