METHODS AND SYSTEMS FOR AUTOMATICALLY IDENTIFYING DETECTION PARAMETERS FOR AN IMPLANTABLE MEDICAL DEVICE

摘要

An initial set of parameters for operating one or more detection tools is automatically derived and subsequently adjusted so that each detection tool is more or less sensitive to signal characteristics in a region of interest. Detection tool(s) may be applied to physiological signals sensed from a patient (such as EEG signals) and may be configured to run in an implanted medical device that is programmable with the parameters to look for rhythmic activity, spiking, and power changes in the sensed signals, etc. A detection tool may be selected and parameter values derived in a logical sequence and/or in pairs based on a graphical representation of an activity type which may be selected by a user, for example, by clicking and dragging on the graphic via a GUI. Displayed simulations allow a user to assess what will be detected with a derived parameter set and then to adjust the sensitivity of the set or start over as desired.

主权项

1. A method of deriving a detection tool implemented in an active implantable device implantable in a patient, said method comprising:
defining a first region of interest in a portion of a signal; establishing a first proposed detection tool based on the first region of interest; evaluating performance of the first proposed detection tool against a detection criterion; and if the detection criterion is not met, establishing a second proposed detection tool based on a second region of interest, the second region of interest being defined by detection outputs of the first proposed detection tool.
