A further clinical review of this event was performed and identified the event to be mdr reportable as a serious injury pursuant to 21 cfr part 803.A mfg review was conducted.The lot met all released criteria.This is the only complaint reported to date for corporate lot number gfxj0877, for the issue.The investigation is inconclusive, as the sample was not returned for eval.Per the ifu, after advancing the guidewire and crosser catheter to the lesion site.The guidewire needs to be withdrawn approximately 1cm within the catheter so that the tip of the crosser catheter is the leading edge.It is likely that the user did not withdraw the guidewire into the distal tip of the crosser catheter prior to activating the crosser.Having the guidewire fully advanced through the distal tip of the crosser catheter during activation could cause the guidewire to break.Therefore, the root cause is most likely user related.The crosser catheter instructions for use (ifu) provides general instructions for use of the device, as well as warnings, precautions, and potential complications associated with the device.
