MAINTAINING STIMULATION THERAPY EFFICACY
First Claim
1. An apparatus comprising:
- a therapy circuit configured to provide electrical neural stimulation therapy to a neural stimulation target of a subject using a first set of a plurality of implantable electrodes, wherein the first set of the plurality of implantable electrodes provides the neural stimulation to a first region of the neural stimulation target;
a switching circuit communicatively coupled to the therapy circuit and configured to change the delivery of therapy among the plurality of implantable electrodes; and
a control circuit configured to;
initiate delivery of the neural stimulation therapy to a first subset of the first set of electrodes during a therapy session;
change the therapy delivery from the first subset of electrodes to at least a second subset of electrodes of the first set of the plurality of implantable electrodes; and
recurrently alternate the therapy delivery among the first subset and the at least second subsets of electrodes during the same therapy session.

Abstract
An apparatus comprises a therapy circuit configured to provide electrical neural stimulation therapy to a subject using a first set of a plurality of implantable electrodes, a switching circuit communicatively coupled to the therapy circuit and configured to change the delivery of therapy among the plurality of implantable electrodes, and a control circuit. The control circuit is configured to initiate delivery of the neural stimulation therapy to a first subset of the first set of electrodes during a therapy session, change the therapy delivery from the first subset of electrodes to at least a second subset of electrodes of the first set of the plurality of implantable electrodes, and recurrently alternate the therapy delivery between the first and second subsets of electrodes during the same therapy session.

11. A method comprising:
-
initiating delivery of electrical neural stimulation therapy to a neural stimulation target of a subject using an IMD, wherein the therapy is delivered to a first set of a plurality of implantable electrodes during a therapy session and the first set of electrodes provides the neural stimulation to a first region of the neural stimulation target; delivering the therapy using a first subset of electrodes of the first set of the plurality of implantable electrodes; changing the therapy delivery from the first subset of electrodes to at least a second subset of electrodes of the first set of the plurality of implantable electrodes, wherein at least one electrode of the second subset of electrodes is different from the first subset of electrodes; and recurrently alternating the therapy delivery among the first subset and the at least second subset of electrodes during the same therapy session. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
