Manufacturer Narrative

This issue was not confirmed as the device was not returned for investigation.The root cause of the reported issue cannot be determined.A possible root cause is that the tubing was kinked on the wound side of the controlled leak path.The renasys system provides blockage detection from the controlled leak path (the t-connector) to the canister.By design, the device will not alarm for blockage if the tubing is occluded below the t-connector (controlled leak path) on the wound side.It is recommended that the device be returned for investigation to rule out a possible device malfunction.The renasys ez has been replaced with the renasys ez plus, which has some new features and modifications.In addition, due to reports of similar complaints, smith & nephew has issued car02714 to initiate renasys product labeling updates.These labelling updates will provide enhanced information on the functionality of the alarms as they relate to the design of the device, and scenarios that can occur in clinical settings which may impact alarm functionality.This medical device report (mdr) is being submitted by smith & nephew as a result of a retrospective review of complaints, including adverse events, as part of corrective and remediation actions following the issuance of the 483 issued november 26, 2013 to smith & nephew, inc.(b)(4).Smith & nephew is performing a two-year retrospective review of complaint files to re-assess reportability criteria and reporting decisions made for complaints recorded during the time period under review.This complaint has been re-assessed in accordance under the provisions of 21cfr 803.50 and deemed reportable as an mdr.We are submitting one (1) initial, 30 day report, medwatch fda form 3500a, for a purported device malfunction which occurred while using the renasys ez negative pressure wound therapy.
