1-10. (canceled)
A medical device for use in a patient comprising:
- a transvenous stimulation lead, the stimulation lead including at least one stimulation electrode configured to be placed in a vein adjacent to at least one phrenic nerve of the patient;
- an implanted medical device (IMD) configured to be implanted in a body of the patient, the IMD configured to be electrically connected to the at least one stimulation electrode;
- a respiration sensor configured to provide a respiration signal to the IMD;
- and control logic incorporated within the IMD, the control logic configured to analyze the respiration signal and deliver stimulation pulses to maintain activation of at least a portion of a diaphragm of the patient the stimulation pulses being selected from a group including consistent amplitude stimulation pulses, progressively increasing amplitude stimulation pulses, progressively decreasing amplitude stimulation pulses, and pulses in which an amplitude of the stimulation pulses increases and then decreases.
