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.
Claims17
A method comprising:
- applying a compressive force to an 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;
- advancing the actuation mechanism towards an actuation mechanism distal interface;
- actuating the actuation mechanism along an actuation mechanism guide wherein a portion of the actuation mechanism guide is disposed in an inner bore of the handle;
- 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 an and an optic fiber proximal end;
- extending the shape memory sleeve from the housing sleeve distal end;
- extending the optic fiber from the housing sleeve distal end wherein the optic fiber distal end is adjacent to a shape memory sleeve distal end;
- and
- curving the optic fiber.
