1. A system for treating an ocular condition of a patient, comprising:
- an ocular implant sized for placement within an eye, the implant comprising;
an electrically powered treatment element; and
an antenna configured to receive energy for operating the electrically powered treatment element; and
a wearable external system comprising;
a transmitter sized to be carried on or adjacent the head of the patient for disposal adjacent the eye, the transmitter being arranged to emit an electromagnetic flux field to energize the antenna and provide power to operate the electrically powered treatment element of the implant, the transmitter comprising a transmission antenna that emits the electromagnetic flux field; and
a flux shunt disposed within the electromagnetic flux field, the transmission antenna being disposed between the flux shunt and the implant; and
a power source in communication with the transmitter and configured to provide power to the transmitter to emit the electromagnetic flux field.

Abstract
A system for treating an ocular condition of a patient includes an electrically powered ocular implant sized for placement within an eye and includes a transmitter sized to be carried on or adjacent the head of the patient for disposal adjacent the eye. The transmitter includes a transmission antenna that emits an electromagnetic flux field sufficient to energize the ocular implant and includes a flux shunt disposed within the electromagnetic flux field. The transmission antenna may be disposed between the flux shunt and the implant.

15. A method of powering an ocular implant sized for implantation in an eye of a patient comprising:
-
generating an electromagnetic flux field with a transmitter worn by the patient and disposed at a location relative to the ocular implant so that the electromagnetic flux field encompasses the implant; limiting the electromagnetic flux field in a direction away from the implant in a manner that increases the electromagnetic flux field in a direction toward the implant; and
receiving energy at the implant from the electromagnetic flux field to power an electrically driven element on the implant to treat an ocular condition. - View Dependent Claims (16, 17)
