Abstract

An electrical energy applicator directs electrical energy from the electrical energy source to a distal end, which positionable at a surface of an eye. The energy conducting applicator includes a first conductor and a second conductor separated by a gap. The first conductor has a first contact surface at the distal end, and the second conductor has a second contact surface at the distal end. The first conductor and/or the second conductor has a length that is adjustable by a biasing element. The first contact surface of the first conductor is movable relative to the second contact surface of the second conductor. The first contact surface and the second contact surface are adjustably positionable simultaneously against the surface of the eye to deliver energy to the eye according to a pattern defined by the first contact surface, the second contact surface, and the gap.

Claims

1. A device for applying therapy to an eye, the system comprising:

an electrical energy applicator extending from a proximal end to a distal end, the energy conducting applicator including, at the proximal end, a connection to an electrical energy source, the energy conducting applicator being adapted to direct electrical energy from the electrical energy source to the distal end, the distal end being positionable at a surface of an eye, the energy conducting applicator including a first conductor and a second conductor separated by a gap, the first conductor having a first contact surface at the distal end, the second conductor having a second contact surface at the distal end, at least one of the first conductor and the second conductor having a length that is adjustable by a biasing element, the first contact surface of the first conductor being movable relative to the second contact surface of the second conductor, the first contact surface and the second contact surface being adjustably positionable simultaneously against the surface of the eye to deliver energy to the eye according to a pattern defined by the first contact surface, the second contact surface, and the gap.

2. The device of claim 1, wherein the first conductor is an outer conductor and the second conductor is an inner conductor disposed in the first conductor.

3. The device of claim 2, wherein outer conductor and the inner conductor are substantially cylindrical and concentric at the distal end, and the gap at the distal end is substantially annular.

4. The device of claim 2, wherein the biasing element forms a part of a conducting body of the outer conductor, the second contact surface of the inner conductor is recessed relative to the first contact surface of the outer conductor, and the length of the outer conductor is reduced by compressing the biasing element when the first contact surface of the outer conductor is positioned against the eye surface to allow the second contact surface of the inner conductor to be moved against the eye surface.

5. The device of claim 1, wherein the gap is non-annular or asymmetric.

6. The device of claim 1, wherein at least one of the first conductor and the second conductor includes a distal segment at the distal end, the distal segment being connected to the biasing element and being movable relative to the proximal end.

7. The device of claim 1, wherein the biasing element forms a part of a conducting body of the first conductor or the second conductor.

8. The device of claim 1, wherein the biasing device is a coil spring.

9. The device of claim 1, wherein one of the first contact surface and the second contact surface is recessed relative to the other of the first contact surface and the second surface.

10. The device of claim 1, wherein the energy conducting applicator includes a sensor system that senses contact between at least one of the first contact surface and the second contact surface against the surface of an eye.

18. The device of claim 1, wherein the biasing element forms a part of a conducting body of the first conductor or the second conductor.

11. A method for applying therapy to an eye, the method comprising:

positioning a distal end of an electrical energy applicator at a surface of an eye, the electrical energy applicator extending from a proximal end to the distal end, the energy conducting applicator including, at the proximal end, a connection to an electrical energy source, the energy conducting applicator including a first conductor and a second conductor separated by a gap, the first conductor having a first contact surface at the distal end, the second conductor having a second contact surface at the distal end, at least one of the first conductor and the second conductor having a length that is adjustable by a biasing element, the first contact surface of the first conductor being movable relative to the second contact surface of the second conductor, the first contact surface and the second contact surface being adjustably positionable simultaneously against the surface of the eye; and

directing, via the energy conducting applicator, electrical energy from the electrical energy source to the surface of the eye according to a pattern defined by the first contact surface, the second contact surface, and the gap.

12. The method of claim 11, wherein positioning the distal end of the electrical energy applicator at the surface of the eye comprises:

positioning the first contact surface against the eye surface; and

moving the second contact surface against the eye surface by compressing the biasing element in the first conductor and reducing the length of the first conductor.

13. The method of claim 11, wherein the first conductor is an outer conductor and the second conductor is an inner conductor disposed in the first conductor.

14. The method of claim 13, wherein outer conductor and the inner conductor are substantially cylindrical and concentric at the distal end, and the gap at the distal end is substantially annular.

15.
