Abstract

A steerable laser probe may include a handle, an actuation structure of the handle, a housing tube, a flexible tube, an optic fiber, and a wire having a pre-formed curve. The flexible tube may be disposed within the housing tube wherein a distal end of the flexible tube projects out from a distal end of the housing tube. The optic fiber may be disposed within an inner bore of the handle, the housing tube, and the flexible tube. The wire may be disposed within the housing tube.

Claims

1. A laser probe comprising:
