International Classification:
A61N 1/00
US Classification:
607 57
Abstract:
Apparatus and method for at least partially fitting a medical implant system to a recipient is described. The medical implant system is configured to provide electrical stimulation and at least one other mode of stimulation to the recipient. These apparatuses and methods comprise executing a genetic algorithm to select a set of parameter values for the medical implant system. This genetic algorithm may comprise generating successive generations of child populations and then providing a determined set of parameter values to the medical implant system for use in providing stimulation to the recipient.

8401978, Mar 19, 2013
Filed:
Sep 10, 2009
Appl. No.:
12/557233
Inventors:
Sean Lineaweaver - Parker CO, US
Assignee:
Cochlear Limited - Macquarie University, NSW
International Classification:
G06F 15/18
US Classification:
706 12, 607 57
Abstract:
Apparatus and method for at least partially fitting a medical implant system to a patient is described. These apparatuses and methods comprise executing a genetic algorithm to select a set of parameter values for the medical implant system. This genetic algorithm may comprise generating successive generations of child populations until a confidence threshold is reached. This confidence threshold comprises determining whether the values of each parameter value to be selected have converged on particular value with a specified confidence level. In determining whether the values have converged, one or more initial generations of the search may be excluded in computing the likelihood that the value has converged.

Abstract:
Apparatus and method for at least partially fitting a medical implant system to a patient is described. These apparatuses and methods comprise using a dynamic mutation rate. This genetic algorithm may comprise generating successive generations of child populations. In executing the genetic algorithm, children may undergo mutations based on a mutation rate. This mutation rate may be dynamic and be based on the characteristics of the children in the generation. Additionally, values may be frozen during execution of the genetic algorithm if the likelihood that the value has converged on a particular value exceeds a threshold.

Filed:
Sep 10, 2009
Appl. No.:
12/557242

Sean Lineaweaver - Parker CO, US
Assignee:
Cochlear Limited - Lane Cove
International Classification:
A61F 11/04
A61N 1/36
A61N 1/36
US Classification:
607 57
Abstract:
A fitting system that may be used by a recipient to determine stimulation level parameters, such as threshold and/or maximum comfort levels, for a stimulating medical device is provided. These parameters may be for MAPs that may be used by a genetic algorithm in fitting a stimulating medical device. In obtaining these parameters, an internal component implanted in a recipient may apply stimulation to the recipient. In response, the recipient, using a user interface, may their information regarding their perception of the applied stimulation. This response may then be used to determine a stimulation level parameter that is then transmitted to the stimulation medical device for use in applying stimulation.
