Neurostimulation system with three-dimensional lead migration detection and automatic neurostimulation correction
First Claim
1. A neurostimulation system configured for providing therapy to a patient, comprising:
- at least one implantable neurostimulation lead configured for being implanted adjacent target tissue of the patient;
an implantable neurostimulator configured for delivering electrical stimulation energy to the at least one implantable neurostimulation lead in accordance with a current set of stimulation parameters;
monitoring circuitry configured for taking at least one measurement indicative of a three-dimensional migration of the at least one neurostimulation lead from a baseline position; and
at least one controller/processor configured for determining whether the three-dimensional migration of the at least one neurostimulation lead from the baseline position has occurred based on the at least one measurement, and, based on the determined three-dimensional migration, generating a new set of stimulation parameters, and reprogramming the implantable neurostimulator with the new set of stimulation parameters,wherein the target tissue is a spinal cord, the at least one neurostimulation lead comprises at least two neurostimulation leads, and the at least one measurement is indicative of a rostro-caudal migration and a media-lateral migration between the at least two neurostimulation leads, and a dorsal-ventral migration of the at least two neurostimulation leads relative to the spinal cord.

Abstract
A neurostimulation system configured for providing therapy to a patient, comprises at least one implantable neurostimulation lead configured for being implanted adjacent target tissue of the patient, and an implantable neurostimulator configured for delivering electrical stimulation energy to the implantable neurostimulation lead(s) in accordance with a set of stimulation parameters capable, and monitoring circuitry configured for taking at least one measurement indicative of a three-dimensional migration of the neurostimulation lead(s) from a baseline position. The neurostimulation system further comprises at least one controller/processor configured for determining whether the three-dimensional migration of the neurostimulation lead(s) from the baseline position has occurred based on the measurement(s), and, based on the determined three-dimensional migration, generating a new set of stimulation parameters, and reprogramming the implantable neurostimulator with the new set of stimulation parameters.
