The following were reviewed as part of this investigation: patient severity, frequency analysis, applicable previous investigation(s), sample (if available), applicable fmea documents, labeling, and applicable manufacture records.Based on a review of this information, the following was concluded: the complaint of ballooning during flushing is confirmed, and the cause is determined to be use-related.The device returned was found to be a segment of an extension leg and main tubing of a broviac 4.2 fr single lumen catheter.Visual observation found that the printing on the extension leg was largely faded and residues were found on the device, particularly the clamp; these are signs of extended use.Tactual evaluation found that the clamping sleeve manifested some tensile weakness and various impressions or clamping marks.Functional testing found that ballooning in the clamping sleeve occurred during infusion.The infusate did not immediately drain from the aneurysm when infusion was stopped.Massaging the catheter eliminated the aneurysm.This is typical of a break within inner tubing, causing redirection of flow into the clamping sleeve.Microscopic evaluation found a transverse hole at the point the internal portion of the luer adaptor terminated within the innermost tubing.The edges of this hole were rough a second hole was found in the innermost tubing on the same side, with several branches and much straighter edges.Examining the outer surface of the middle tubing found a longitudinal hole corresponding to the roughened hole and a straight-edged branched hole corresponding to the other.The damage appears to have been caused by contact of the internal portion of the luer adaptor against the inner tubing.This can occur when the device is clamped too near the luer adaptor, resulting in compression of the catheter between the internal portion of the luer adaptor and the clamp.This may also occur when the catheter is manipulated such that the luer adaptor stem rubs or pushes against the inner tubing.The complaint is determined to be use-related.The ifu states: ¿avoid accidental device contact with sharp instruments and mechanical damage to the catheter material.Use only smoothedged atraumatic clamps or forceps.¿ ¿clamping the catheter selection of the catheter clamp is very important since the catheter is vital to your care.The wrong clamp can damage the catheter.Follow these three rules for clamping: use only smooth-edged clamps.Always clamp the catheter over the reinforced clamping sleeve or tape tab, as instructed by your nurse.Never clamp over the reinforced segment directly adjacent to the connector.(see diagram) follow the directions of your doctor or nurse regarding when to clamp.Most hickman* and broviac* catheters come with pre-attached clamps and reinforced clamping sleeves.¿ a lot history review (lhr) of huaw0287 showed no other similar product complaint(s) from this lot number.
