Abstract
A method and system of providing therapy to a patient implanted with an array of electrodes is provided. A train of electrical stimulation pulses is conveyed within a stimulation timing channel between a group of the electrodes to stimulate neural tissue, thereby providing continuous therapy to the patient. Electrical parameter is sensed within a sensing timing channel using at least one of the electrodes, wherein the first stimulation timing channel and sensing timing channel are coordinated, such that the electrical parameter is sensed during the conveyance of the pulse train within time slots that do not temporally overlap any active phase of the stimulation pulses.

2. A method of providing therapy to a patient via an implanted array of electrodes, the method comprising:
-
delivering a first sequence of electrical stimulation pulses through a first channel to a first group of electrodes from the implanted array of electrodes to stimulate neural tissue and provide continuous therapy to the patient, the first sequence of electrical stimulation pulses having an active phase and an inactive phase; and sensing an electrical parameter through a sensing channel using at least one sensing electrode from the first group of electrodes such that the sensing occurs during delivery of the first sequence of electrical stimulation pulses, but not during the active phase of the first sequence of electrical stimulation pulses. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11)
