Controlling stimulation parameters of implanted tissue stimulators
First Claim
1. An apparatus comprising:
- an implantable stimulation device to elicit a response in a tissue by delivering one or more stimuli, the stimulation device including a stimulus delivery element to deliver the one or more stimuli to elicit the response;
a memory to store a range value identifying a range of values of a stimulation parameter relative to a first value; and
a controller to control delivery of the one or more stimuli by the stimulus delivery element accordance with the range value, the stimulation parameter characterizing the one or more stimuli to be delivered by the stimulation device.

Abstract
Systems and techniques for controlling the stimulation of tissue. In one aspect, an apparatus includes an implantable stimulation device to elicit a response in a tissue by delivering one or more stimuli. The stimulation device includes a stimulus delivery element to deliver the one or more stimuli to elicit the response, a memory to store a range value identifying a range of values of a stimulation parameter relative to a first value, and a controller to control delivery of the stimuli by the stimulus delivery element in accordance with the range value. The stimulation parameter characterizes the stimuli to be delivered by the stimulation device.

15. An apparatus comprising:
an implantable stimulation device configured to deliver one or more stimuli to elicit a response from a tissue, the stimulation device including a stimulus delivery element configured to deliver the one or more stimuli to elicit the response;
a transceiver configured to exchange data with an extracorporeal device;
a controller configured to control delivery of the one or more stimuli by the stimulus delivery element in light of the data exchanged with the extracorporeal device; and
a hardware limiter configured to limit a range of a characteristic of the one or more stimuli to be delivered by the stimulus delivery element independently of the controller. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A system for stimulating tissue, comprising:
-
an implanted portion including a stimulator configured to elicit a response from tissue using a stimulus, and a data transmitter configured to transmit, over a data link, data regarding whether the stimulator is active; and
an extracorporeal portion including a data receiver configured to receive the data from the implanted portion over the data link, a user interface configured to receive a proposed change to the stimulus from a user, and a processor configured to hinder the change to the stimulus when the data receiver receives data indicating that the stimulator is not currently active. - View Dependent Claims (23, 24)

25. A method comprising:
-
receiving a stimulation adjustment at an extracorporeal portion of a system for stimulating tissue, the stimulation adjustment proposing a change to one or more aspects of an stimulus to be delivered by an implanted stimulation device to elicit a response from a tissue;
at the extracorporeal portion of the system for stimulating tissue, deciding whether the proposed stimulation adjustment is appropriate by determining if the proposed stimulation adjustment would yield a stimulation parameter outside a range of values of the stimulation parameter, the stimulation parameter characterizing the stimulus to be delivered by the implanted stimulation device;
at the extracorporeal portion, if the proposed stimulation adjustment is appropriate, determining a setting for the stimulation parameter based on the proposed stimulation adjustment and transmitting the stimulation parameter setting to the implanted stimulation device; and
at the implanted stimulation device, receiving the stimulation parameter setting from the extracorporeal portion. - View Dependent Claims (26, 27, 28)

29. A method comprising:
-
at an extracorporeal portion of a system for delivering a stimulus to elicit a response from a tissue, comparing a stimulation parameter that would be yielded by a proposed adjustment to the stimulation parameter to a range of values of the stimulation parameter, the stimulation parameter characterizing the electrical signal to be delivered by an implanted portion of the system;
determining, based on the comparison, that the proposed adjustment is inappropriate if the proposed adjustment would violate a boundary on the range of values; and
accommodating the proposed stimulation adjustment by changing a setting of the stimulation parameter to the violated boundary. - View Dependent Claims (30, 31, 32)

33. A method comprising:
-
comparing a proposed adjustment to a stimulation parameter to a range of values of the stimulation parameter, the stimulation parameter characterizing a stimulus to be delivered by an implanted stimulation device to elicit a response from a tissue;
determining, based on the comparison, that the proposed adjustment is inappropriate if the proposed adjustment would be outside the range of values of the stimulation parameter; and
accommodating the inappropriate adjustment by rejecting the inappropriate adjustment to leave the stimulation parameter unchanged. - View Dependent Claims (34)

35. A method comprising:
-
receiving, at an extracorporeal device, a proposed adjustment to a stimulus to be delivered by an implanted device, the stimulus to elicit a response from a tissue;
determining whether the implanted device is active; and
if the implanted device is not active, rejecting the adjustment to leave the stimulus unchanged. - View Dependent Claims (36)
