Controlling electrical stimulation by multiple medical devices

A system comprising:

• a first implantable medical device (IMD) implanted within a first tissue of a patient, the first IMD comprising;
• sensing circuitry configured to generate sensed information representative of an evoked electrical signal elicited by a first stimulation signal delivered from a second IMD different from the first IMD to a second tissue of the patient, the second tissue being at a different location than the first tissue;
• and
• processing circuitry configured to:
• determine, based on the sensed information representative of the evoked electrical signal, one or more stimulation parameters at least partially defining a second stimulation signal;
• and
• control stimulation generation circuitry of the first IMD to deliver the second stimulation signal to the first tissue of the patient according to the one or more stimulation parameters.

A method comprising:

• sensing, via sensing circuitry of a first implantable medical device (IMD) implanted within a first tissue of a first region of a patient, information representative of an evoked electrical signal elicited by a first stimulation signal delivered from a second IMD different from the first IMD to a second tissue of a second region of the patient;
• determining, by processing circuitry of the first IMD and based on the sensed information representative of the evoked electrical signal, one or more stimulation parameters at least partially defining a second stimulation signal;
• and
• controlling, by the processing circuitry, stimulation generation circuitry of the first IMD to deliver the second stimulation signal to the first tissue according to the one or more stimulation parameters.

A computer-readable medium comprising instructions that, when executed, cause processing circuitry of a first implantable medical device (IMD) to:

• sense, via sensing circuitry of the first IMD implanted within a first tissue of a first region of a patient, information representative of an evoked electrical signal elicited by a first stimulation signal delivered from a second IMD different from the first IMD to a second tissue of a second region of the patient;
• determine, based on the sensed information representative of the evoked electrical signal, one or more stimulation parameters at least partially defining a second stimulation signal;
• and
• control stimulation generation circuitry of the first IMD to deliver the second stimulation signal to the first tissue according to the one or more stimulation parameters.
