The device history record could not be reviewed because the lot number was not provided.There was no patient injury.The picc broke and had to be removed.Visual inspection of returned product confirmed the breakage, which occurred just below the nose of the overmolded extension set.The area of separation was reviewed under magnification.The tubing appeared to have been fully formed (no voids were noted).The edges of the separated tubing were jagged which is characteristic of undue force to the catheter.Potential times at which this force may have been applied to the catheter include: flushing the catheter with excessive pressure, such as flushing with a syringe smaller than 10 ml, or applying pressure despite resistance when flushing.Using the catheter for high pressure mechanical injection.Advancing or removing the catheter despite experiencing resistance.The ifu includes the following guidelines to inform clinicians of these causes and mitigate the occurrence of breakage: "use a 10 ml syringe design to flush the catheter.Do not use force to flush the catheter as a 10 ml syringe design has the potential to generate high pressure (greater than 40 psi) capable of rupturing the catheter." "never use force to flush the catheter if resistance is met." "never use the catheter for high-pressure injection.Syringes smaller than 10 ml and mechanical high-pressure injectors can generate pressures capable of rupturing the catheter." this complaint may be related to the handling of the device in the user environment.
