Steerable laser probe
First Claim
1. A method for photocoagulating tissue within an inner eye comprising:
- applying a force to an actuation structure of a handle wherein the handle has a handle distal end and a handle proximal end, and wherein the actuation structure has a plurality of actuation arms;
compressing the actuation structure, wherein compressing the actuation structure causes;
retraction of an actuation cone into the actuation structure wherein the actuation cone has an actuation cone distal end and an actuation cone proximal end;
retraction of a housing sleeve relative to both an optic fiber and shape memory sleeve wherein the housing sleeve has a housing sleeve distal end and a housing sleeve proximal end;
curving of the shape memory sleeve wherein the shape memory sleeve has a shape memory sleeve distal end and a shape memory sleeve proximal end; and
curving of the optic fiber wherein the optic fiber has an optic fiber distal end and an optic fiber proximal end;
aiming the optic fiber distal end at a first photocoagulation target tissue within an inner eye wherein the first photocoagulation target tissue is within a particular transverse plane of the inner eye;
cauterizing the first photocoagulation target tissue;
rotating the handle; and
aiming the optic fiber distal end at a second photocoagulation target tissue within the inner eye wherein the second photocoagulation target tissue is within a particular frontal plane of the inner eye.

Abstract
A steerable laser probe may include a handle having a handle proximal end and a handle distal end, an actuation structure of the handle, a housing sleeve, a shape memory sleeve at least partially disposed within the housing sleeve, and an optic fiber disposed within the shape memory sleeve and within an inner bore of the handle. A compression of the actuation structure may be configured to gradually curve the optic fiber. A compression of the actuation structure may be configured to gradually straighten the optic fiber. A decompression of the actuation structure may be configured to gradually curve the optic fiber. A decompression of the actuation structure may be configured to gradually straighten the optic fiber.
