Current standard multi-filar cables have an insulating layer with an additional adhesive layer which is bonded together and normally flattened. However, the rough design, lack of smoothness and difficulty associated with separating the individual cables causes issues during various assembly stages.
We listened to our customers and noted the demand for increasing the volume of signals needed in these multi-filar cable assemblies, which in turn makes these cables more difficult to handle. By sandwiching cables between thin PTFE tape, we have developed multi-filar cables without increasing the outer cable diameter while also making cable insertion, separation and subassembly easier. Below are samples which represent how we can combine various cable configurations together and sandwich them in PTFE to suit the needs of new catheter concepts.
