In Reply:--Hub separation in Arrow's triple lumen catheter is an extremely rare occurrence, as documented by our statistical quality assurance data and by the millions of multi-lumen catheters used successfully each year. Arrow encourages immediate reporting of any incidents involving our products and the return of the product for analysis, so that the appropriate engineering or manufacturing intervention can be made as quickly as possible.
