The Lungpacer DPT System™ is designed to electrically stimulate the phrenic nerves of a patient through a temporary, single-use indwelling multi-electrode stimulating catheter (LIVE Catheter) that is attached by means of the Intermediate Cable to an external pulse generator called the Lungpacer Control Unit. Also, connected to the Lungpacer Control Unit is the Handheld Controller that may be used as an alternative to the user interface touchscreen of the Lungpacer Control Unit to trigger the delivery of electrical charge to the electrodes of the LIVE Catheter.
