A circuit system includes a user interface, voltage source, and a terminal bank connected to the voltage source. The circuit can be used in a powered catheter system where the catheter includes a structural reinforcement layer such as a braid comprised of one or more wires. The reinforcement layer can be used to convey a current or signal in a powered catheter. The catheter may utilize a hypotube element which provides integrated sensors in order to power and control multiple systems in the powered catheter.
