On (b)(6) 2016, the reporter contacted animas, alleging a occlusion (frequent/persistent) issue.The reporter was not able to provide further information during the initial complaint.Customer technical support made attempts to contact the reporter for additional information and troubleshooting, without success.There was no indication that the product caused or contributed to an adverse event.This is being reported because the issue may result in a long term cessation of insulin delivery if the user is unable to resolve the alarm.
