Quality assurance product analysis received and examined the returned jetstream xc-2.4 catheter and observed that the wire stuck inside the catheter was a filterwire guide wire.The rest of the unit appeared to be in good condition with no other observable defects or damage.The device would not activate with the filterwire stuck inside and therefore a functional test could not be performed.The weld at the tip of the catheter was separated to investigate the guide wire lumen.The bushing and proximal cap were plugged with teflon.The cause of the problem is the guide wire losing coating and occluding the bushing at the distal end of the catheter.The filterwire guide wire is not listed in the jetstream system ifu as a compatible device.In this reported event, the jetstream catheter was being used in a previously placed stent when it allegedly stalled.The treatment of in-stent restenosis is an off-label use of the jetstream atherectomy system.This event is considered to be a reportable event due to the association between the jetstream device and noted event.
