Complex stimulation channel arrangements

A method, comprising:

• determining the stimulation efficiency of a combined complex stimulation channel that is part of a set of complex stimulation channels associated with a tissue-stimulating prosthesis, wherein each complex stimulation channel includes one or more electrodes;
• identifying a first complex stimulation channel in the set of complex stimulation channels that has an associated stimulation efficiency that is below a stimulation efficiency limit;
• and
• combining the first complex stimulation channel with an adjacent complex stimulation channel to create an additional combined complex stimulation channel that replaces both the first complex stimulation channel and the adjacent complex stimulation channel.

A system, comprising:

• one or more network interface devices;
• a memory;
• and
• a processor configured to:
• determine a stimulation efficiency for each complex stimulation channel in a set of complex stimulation channels associated with a tissue-stimulating prosthesis, wherein each complex stimulation channel includes one or more electrodes,
• identify a first complex stimulation channel in the set of complex stimulation channels that has an associated stimulation efficiency that is below a stimulation efficiency limit, and
• combine the first complex stimulation channel with an adjacent complex stimulation channel to create a combined complex stimulation channel that replaces both the first complex stimulation channel and the adjacent complex stimulation channel.
