1. A method comprising:
- applying a compressive force to at least one actuation arm of a plurality of actuation arms of an actuation structure of a handle wherein the handle has a handle distal end and a handle proximal end;
compressing the actuation structure;
extending an actuation mechanism relative to the handle proximal end;
extending a portion of the actuation mechanism out from the actuation structure;
advancing an actuation guide interface within an actuation channel;
extending a shape memory sleeve relative to a housing sleeve wherein the housing sleeve has a housing sleeve distal end and a housing sleeve proximal end;
extending an optic fiber relative to the housing sleeve wherein the optic fiber has an optic fiber distal end and an optic fiber proximal end and wherein the optic fiber distal end is adjacent to a distal end of the shape memory sleeve;
extending the shape memory sleeve out from the housing sleeve distal end;
extending the optic fiber out from the housing sleeve distal end; and
curving the optic fiber relative to the housing sleeve.

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.

14. A method comprising:
-
reducing a compressive force applied to at least one actuation arm of a plurality of actuation arms of an actuation structure of a handle wherein the handle has a handle distal end and a handle proximal end; decompressing the actuation structure; retracting an actuation mechanism relative to the handle proximal end; retracting a portion of the actuation mechanism into the actuation structure; retracting an actuation guide interface within an actuation channel; retracting a shape memory sleeve relative to a housing sleeve wherein the housing sleeve has a housing sleeve distal end and a housing sleeve proximal end; retracting an optic fiber relative to the housing sleeve wherein the optic fiber has an optic fiber distal end and an optic fiber proximal end and wherein the optic fiber distal end is adjacent to a distal end of the shape memory sleeve; retracting the shape memory sleeve into the housing sleeve distal end; retracting the optic fiber into the housing sleeve distal end; and straightening the optic fiber relative to the housing sleeve. - View Dependent Claims (15, 16, 17, 18, 19, 20)
