Device site stimulation for notification
First Claim
1. An implantable medical device comprising:
- one or more device site electrodes located proximate to an implant location for the implantable medical device;
a lead-borne electrode array located distally from the implant location; and
a processor to control delivery of therapeutic stimulation via a first electrode configuration and patient notification stimulation via a second electrode configuration,wherein the lead-borne electrode array includes each cathode for the first electrode configuration, and the one or more device site electrodes are configurable as anodes for the first electrode configuration, andwherein the one or more device site electrodes include each cathode for the second electrode configuration, and the lead-borne electrode array includes each anode for the second electrode configuration.

Abstract
The disclosure is directed to techniques for delivering electrical stimulation for patient notification. An implantable medical device (IMD) may deliver patient notification stimulation via one or more device site electrodes, e.g., electrodes located proximate to an implant site for the IMD, configured as cathodes. Anodes for delivery the patient notification stimulation may be located in an electrode array that is provided by one or more leads and located distally from the implant site, e.g., an electrode array located at one or more target sites for delivery of stimulation therapy. In some embodiments, the IMD may inhibit the patient notification stimulation for a period in response to input from the patient, and then resume the stimulation at the end of the period. In this manner, the notification stimulation may be “snoozed” like an alarm clock. When the stimulation resumes, it may be different, e.g., more urgent, then prior to inhibition.
