SYSTEM AND METHOD FOR MAPPING DIAPHRAGM ELECTRODE SITES

摘要

A signal source coupled to one or more electrodes in the vicinity of the diaphragm for mapping therapeutic electrode sites. A stimulus signal from the signal source may be applied to the one or more electrodes to produce activation of the diaphragm. Activation of the diaphragm is sensed to provide information that may be correlated with the stimulus signal. The correlated information may be used to identify a therapeutic locus for a therapeutic electrode. An electrical stimulus comprising a series of pulses may be applied to the one or more electrodes to elicit a desired breathing response. The electrical stimulus may be applied between intrinsic breathing cycles, or between regulated breathing cycles. More than one electrode may be supported on a single substrate. The substrate may configured to be positioned on the diaphragm. A hierarchy of stimuli may be applied to a set of electrodes.
