## Abstract

A steerable laser probe may include a handle having a handle distal end and a handle proximal end, a housing sleeve disposed in an inner bore of the handle configured to project a distance from the handle distal end, an optic fiber disposed in the housing sleeve, a shape memory sleeve disposed over a distal end of the optic fiber, and a light source configured to connect to a proximal end of the optic fiber. The shape memory sleeve may be configured to curve the distal end of the optic fiber at an angle, e.g., 90 degrees, when the shape memory sleeve is not contained within the housing sleeve.

## Claims

### Claim 1

A laser probe comprising:
a handle having a handle distal end and a handle proximal end;
an actuation structure of the handle;
a plurality of actuation arms of the actuation structure;
a nosecone having a nosecone distal end and a nosecone proximal end;
an actuation mechanism having an actuation mechanism distal end and an actuation mechanism proximal end wherein the actuation mechanism is at least partially disposed in the actuation structure;
a housing sleeve having a housing sleeve distal end and a housing sleeve proximal end wherein the housing sleeve is disposed in the nosecone wherein the housing sleeve distal end extends from the nosecone distal end;
a shape memory sleeve having a shape memory sleeve distal end and a shape memory sleeve proximal end wherein the shape memory sleeve is disposed in the handle and the housing sleeve; and
is an optic fiber having an optic fiber distal end and an optic fiber proximal end wherein the optic fiber is disposed in the handle, the shape memory sleeve, and the housing sleeve and wherein a compression of the actuation structure is configured to curve the optic fiber.

### Claim 2 (depends on 1)

### Claim 8 (depends on 1)

The laser probe of claim 1 wherein the compression of the actuation structure is configured to curve the shape memory sleeve.

### Claim 9 (depends on 1)

The laser probe of claim 1 wherein a decompression of the actuation structure is configured to straighten the optic fiber.

### Claim 10 (depends on 1)

The laser probe of claim 1 wherein a decompression of the actuation structure is configured to straighten the shape memory sleeve.

### Claim 11

A laser probe comprising:
a handle having a handle distal end and a handle proximal end;
an actuation structure of the handle;
a plurality of actuation arms of the actuation structure;
a nosecone having a nosecone distal end and a nosecone proximal end;
an actuation mechanism having an actuation mechanism distal end and an actuation mechanism proximal end wherein the actuation mechanism is at least partially disposed in the actuation structure;
a housing sleeve having a housing sleeve distal end and a housing sleeve proximal end wherein the housing sleeve is disposed in the nosecone wherein the housing sleeve distal end extends from the nosecone distal end;
a shape memory sleeve having a shape memory sleeve distal end and a shape memory sleeve proximal end wherein the shape memory sleeve is disposed in the handle and the housing sleeve; and
an optic fiber having an optic fiber distal end and an optic fiber proximal end wherein the optic fiber is disposed in the handle, the shape memory sleeve, and the housing sleeve and wherein a decompression of the actuation structure is configured to straighten the optic fiber.

### Claim 12 (depends on 11)

The laser probe of claim 11 wherein the decompression of the actuation structure is configured to retract a portion of the actuation mechanism into the actuation structure.
