It was reported that "proximal lumen extension tubing stretched and expanded after patient had a ct scan".Additional information received states that the cvc has placed the same day right before the ct scan.During the scan, contrast was injected via a high pressure ct scan injection.The other two lumens are patent, able to flush and infuse fluids and pull back blood.The line was removed and it was decided by the doctor to not replace the line.No patient harm or injury.The patient status is reported as "fine".

(b)(4).The customer returned one, three-lumen cvc for analysis.Signs of use in the form of biological material was observed inside the proximal extension line.Visual analysis revealed that the proximal extension line was stretched/ballooned.The stretching was present along the entire proximal extension line.It was noted that the slide clamp was in the closed position directly adjacent to the luer hub.Kinking was also observed on the line, consistent with the appearance of a closed slide clamp.Additionally, after performing functional testing, biological material was observed inside the proximal extension line/extrusion.It is possible that the biological material or slide clamp occluded the lumen during pressurization, which can contribute to the observed damage, however, it cannot be confirmed if the obstruction was present during use.The inner diameter of the proximal extension line at the white hub measured 0.055", which is within the specification limits of 0.055"-0.059" per the proximal extension line extrusion product drawing.The outer diameter of the extension line could not be accurately measured as the entire line was stretched/ballooned.A lab inventory syringe filled with water was attached to the proximal extension and flushed.Major resistance was experienced when flushing the extension line.Biological material was observed exiting the proximal skive hole, which likely contributed to the resistance experienced.Performed per ifu statement, "flush lumen(s) to completely clear blood from catheter".No obstructions were observed when flushing the medial and distal extension line.A device history record review was performed and no relevant findings were identified.The instructions-for-use (ifu) provided with the kit informs the user, "the maximum pressure of power injector equipment used with the pressure injectable cvc may not exceed 400psi" and also cautions the user "do not exceed ten (10) injections or catheter's maximum recommended flow rate located on product labeling and catheter luer hub to minimize the risk of catheter failure and/or tip displacement".The ifu also contains detailed instructions on proper technique for pressure injection.It warns the user "ensure patency of each lumen of catheter prior to pressure injection to minimize the risk of catheter failure and/or patient complications" and provides explicit instructions for ensuring patency prior to pressure injection: "check for catheter patency: attach 10 ml syringe filled with sterile normal saline.Aspirate catheter for adequate blood return.Vigorously flush catheter." the report of a stretched/ballooned extension line was confirmed through complaint investigation.Visual analysis revealed that the proximal extension line was stretched/ballooned.Biological material was observed to exit from the proximal line during functional testing.Buildup of biological material within the line or an inadvertent closed extension line slide clamp can cause over-pressurization and result in the damage observed on the returned catheter during pressure injection, however, it cannot be confirmed whether an obstruction was present during use.The catheter flushed as expected once the obstruction was removed, the catheter met all relevant dimensional requirements.A device history record review was performed with no relevant findings to suggest a manufacturing related cause.Based on the customer report and investigation , unintentional use error (overpressure) likely caused or contributed to this event.Teleflex will continue to monitor and trend for reports of this nature.Other remarks: n/a.Corrected data: n/a.
