Failure analysis in catheters

From Cambridge Polymer Group, Inc.

A client presented catheter hubs that appeared to be cracking during their manufacturing process. The
hubs were compound structures with polycarbonate embedding electronics and the catheter itself. A
detailed understanding the interaction between the materials and the processes in use was vital to
allow determination of the cause of failure. Cambridge Polymer Group isolated the root-cause and
proposed an alternative manufacturing strategy that the client adopted.
