Abstract
Systems, devices, and methods for use in delivering stimulation to the head of a patient, including examples directed to delivering electrical or other stimulation to the eye of the patient. In some examples eyepieces or eyepatches are configured to deliver electrical or other stimulus to the eye of a patient by being worn on the face of the patient.
Claims29
A patient interface apparatus for delivery of stimulus to a portion of the head of a patient for a session, the patient interface apparatus comprising:
- a first eyepiece adapted to fit about at least one eye of the patient;
- wherein the first eyepiece comprises at least first and second electrodes, the first eyepiece further comprising at least first and second electrical connectors separately coupled to the first and second electrodes;
- wherein the patient interface apparatus further comprises a pulse generator coupled to at least the first and second electrical connectors to issue electrical therapy pulses using the first and second electrodes;
- and
- wherein the pulse generator is configured to:
- monitor a tissue impedance between the first and second electrodes before commencement of the electrical therapy to establish an initial impedance-based threshold for the patient;
- define a session-specific acceptable impedance upper limit on the basis of the initial threshold;
- compare a subsequently monitored tissue impedance to the session-specific acceptable impedance upper limit;
- and
- interrupt or withhold the electrical therapy when the subsequently monitored tissue impedance exceeds the session-specific acceptable impedance upper limit.
A method of treating a patient having a vision disorder comprising:
- having the patient wear a patient interface apparatus for a session comprising:
- (i) a first eyepiece adapted to fit about at least one eye of the patient, wherein the first eyepiece comprises at least first and second electrodes, the first eyepiece further comprising at least first and second electrical connectors separately coupled to the first and second electrodes, and
- (ii) a pulse generator coupled to at least the first and second electrical connectors to issue therapy pulses using the first and second electrodes;
- and
- activating the pulse generator to issue an electrical therapy to the eye using the first and second electrodes as a series of electrical therapy pulses;
- monitoring a tissue impedance between the first and second electrodes before commencement of the electrical therapy to establish an initial impedance-based threshold for the patient;
- defining a session-specific acceptable impedance upper limit on the basis of the initial threshold;
- comparing a subsequently monitored tissue impedance to the session-specific acceptable impedance upper limit;
- and
- interrupting or withholding the electrical therapy when the subsequently monitored tissue impedance exceeds the session-specific acceptable impedance upper limit.
