Apparatus and Method for Visual Stimulation Indication

摘要

Methods and devices for verifying that proper visual stimulation is applied to the visual prostheses are described. In one of the methods, a visual stimulation system implanted on a subject is simulated externally. An external testing device is also discussed.

主权项

1. An external testing device for simulation of a implantable visual prosthesis stimulation system implanted on a subject, comprising:
A non-implantable wireless receiver for wirelessly receiving visual information signals generated from a video processing unit, the non-implantable wireless receiver simulating and mimicking electrical functionalities of the implantable visual prosthesis stimulation system; and a non-implantable display unit, viewable by a clinician, connected to an output of the non-implantable wireless receiver, the non-implantable display unit visually monitoring the visual information signals wirelessly received through the non-implantable wireless receiver and displaying the visual information signals using image elements, in an array pattern simulating and mimicking an array of electrodes of the implantable visual prosthesis stimulation system, each image element corresponding to a specific electrode of the array of electrodes of the implantable visual prosthesis stimulation system, to test the function of the video processing unit.
