(b)(4).Associated mdr#s: 3006425876-2022-01107; 3006425876-2022-01098.The customer returned one 3-l cvc for analysis.Signs of use were observed on the catheter body and inside the extension lines.The catheter appeared intentionally cut.Initial visual inspection of the catheter and extension lines did not reveal any obvious defects or anomalies.After performing functional testing (see below), further visual inspection of the distal extension line revealed a small v-shaped hole in its body.This appearance of the hole is consistent with unintentional contact with sharps (i.E.Scalpel, scissors, etc.) during use.The catheter body length measured 88mm, which is not within the specifications of 157mm-177mm per product drawing.This indicates that 69mm-89mm of the catheter were cut and not returned for analysis.The distal extension line outer diameter measured 2.166mm, which is within the specifications of 2.13mm-2.21mm per product drawing.The proximal extension line inner diameter measured 1.4732mm, which is within the specifications of 1.42mm-1.50mm per product drawing.This indicates that the wall thickness measured within specifications.Functional inspection of the catheter was performed per the instructions-for-use (ifu) provide d with the kit which states, "flush each lumen with sterile normal saline for injection to establish patency and prime lumen(s)." the extension lines were flushed using a lab inventory 10ml syringe.A leak was observed partway down the distal extension line body.A manual tug test confirmed the extension lines were fully secured within their respective hubs.The customer did not provide a lot number; therefore, a device history record review was performed based upon a lot number from the sales history data of the customer.No relevant findings were identified.The instructions for use (ifu) provided with this kit warns the user, "do not secure, staple, and/or suture directly to outside diameter of catheter body or extension lines to reduce risk of cutting or damaging the catheter or impeding catheter flow.Secure only at indicated stabilization locations.".The customer report of an extension line leak was confirmed through complaint investigation of the returned sample.A leak was observed partway down the distal extension line.Visual inspection of the extension line revealed a small hole consistent with unintentional contact with sharps (i.E.Scalpel, scissors, etc.) during use.Based on the appearance of the damage and the customer report that the leak was identified during use, unintentional use error (contact with sharps) likely caused or contributed to this event.Teleflex will continue to monitor and trend for complaints of this nature.
