Pma/510(k)#: k162717.Device evaluation: the evo device of unknown lot number was not returned to cook ireland for evaluation.With the information provided, document based investigation was conducted.This file was created from the attached journal article to capture esophageal perforation.A total of sixty five patients were identified in this study.''five stent types were used: partially covered ultraflex stents (boston scientific), partially covered evolution stents (cook medical), fully covered hanaro stents (mi tech) and partially as well as fully covered wallflex stents (boston scientific).Documents review including ifu review: as the evo (esophageal metal) device from unknown lot number, a review of the relevant manufacturing records cannot be conducted.Prior to distribution all evo (esophageal metal) devices are subject to visual inspection and functional checks to ensure device integrity.These inspections and functional checks are outlined in internal procedures in place at cirl.As per the instructions for use, ifu0061-6, which informs the user about the potential complications "additional complications include, but are not limited to : perforation, hemorrhage, aspiration, reflux, fever, infection, allergic reaction to medication, hypotension, respiratory depression or arrest, cardiac arrhythmia or arrest.Additional complication include, but are not limited to: stent misplacement and/or migration; tumor ingrowth or overgrowth; esophageal ulceration and erosion; nausea; chest or retrosternal pain; foreign body sensation; food bolus impaction; gasbloat; sensitivity to metal components; fistula involving trachea, bronchi or pleural space; intestinal obstruction secondary to migration; mediastinitis or peritonitis; airway compression; tracheal obstruction.On review of the information provided, there is no evidence to suggest that the user did not follow the instructions for use.Root cause review: a definitive root cause could not be determined from the available information.A possible root cause could be attributed to patient condition related, as per instructions for use, perforation is listed as a potential complication following the placement of this device.Summary: complaint is confirmed based on customer testimony.Patient outcome is unknown, patient suffered esophageal perforation, managed with antibiotics.Complaints of this nature will continue to be monitored for potential emerging trends.
