Channel-selective blanking for a medical device system
First Claim
1. A method for providing treatment therapy for a nervous system disorder, comprising:
- (a) detecting a nervous system disorder based on signals received from a set of electrodes;
(b) providing stimulation responsive to the nervous system disorder to a first electrode in the set of electrodes for a first interval, wherein the first electrode is blanked during the stimulation;
(c) in response to the providing of stimulation, determining that a first signal from a second electrode in the set of electrodes includes an artifact; and
(d) blanking the second electrode for a second interval, wherein at least one electrode in the set is not blanked.

Abstract
Apparatuses and methods selectively blank a neurological channel of a medical device system in the treatment of a nervous system disorder. A selected signal of a selected channel may be blanked if it is determined that the selected signal may be affected by an artifact when the medical device system delivers a treatment therapy. The selected signal may be blanked by hardware, in which the selected electrode is disconnected from the selected channel (which may include an selected amplifier) and is connected to a fixed voltage in order to avoid saturation of the selected amplifier. The selected channel may be blanked by software, in which a signal processor is instructed not to process neurological data on the selected channel for a determined time duration. Embodiments may combine hardware and software blanking for the selected signal.

16. A computer readable medium having computer readable instructions for performing steps comprising:
-
(a) detecting a nervous system disorder based on signals received from a set of electrodes; (b) providing stimulation instructions to cause a stimulation pulse responsive to the detected nervous system disorder to be sent to a first electrode in the set of electrodes, wherein the instructions include a first blanking instruction that causes the first electrode to be blanked for a first interval; (c) determining a signal received from a second electrode in the set of electrodes includes an artifact caused by the responsive stimulation; and (d) in response to the determination in (c), providing a second blanking instruction that causes the second electrode in the set of electrodes to be blanked for a second interval, wherein at least one electrode in the set of electrodes is not blanked. - View Dependent Claims (17, 18, 19, 20, 21, 22)
