Qn#(b)(4).The actual device was not returned; however, the customer provided one photo for analysis.The complaint of extension line stretched was able to be confirmed by the photo.A complete visual inspection could not be performed as no sample was returned for analysis.The instructions for use (ifu) provided with this kit warns the user, "precaution: to minimize the risk of damage to extension lines from excessive pressure, each clamp must be opened prior to infusing through that lumen".The customer supplied photo displayed parameters stating "5ml/sec" and "300psi".According to the pressure injection info card provided with this kit, the maximum indicated pressure injection flow rate for the medial extension line is 5ml/sec.R & d also consulted that "if the customer set the injection machine to provide a required flow rate of 5ml/sec, regardless of pressure, the pressure could rise to whatever is necessary to achieve the flow, which may lead to catheter ballooning or bursting".Based on the customer photo, it appears as though the pressure was set to 300 psi which is within the indicated range.The customer report of extension line stretched/ballooned could be confirmed by visual inspection of the customer supplied photo.The image showed an extension line of the catheter ballooned/stretched which appears consistent with damage related to overpressure.Without the device to evaluate, the probable cause could not be determined from the available information.Teleflex will continue to monitor and trend for reports of this nature.
