METHODS AND APPARATUS RELATED TO A SIDE-FIRE ASSEMBLY THAT HAS AN OPTICAL GRATING

摘要

An apparatus may include an optical fiber having an angled grating aligned along a plane non-normal to a longitudinal axis of a distal end portion of the optical fiber. The angled grating may be configured to redirect a first laser energy propagated within the optical fiber and incident on the angled grating to a direction offset from the longitudinal axis. The apparatus may also include a metallic cap coupled to the optical fiber. The metallic cap may have an inner surface configured to redirect a second laser energy incident on the inner surface along the direction offset from the longitudinal axis. The second laser energy being different than the first laser energy.

1. A minimally-invasive medical device comprising:
an optical fiber having a distal end portion configured to be disposed within a body of a patient; and an angled grating disposed at the distal end portion, the angled grating being configured to redirect laser energy-propagated within the optical fiber and incident on the angled grating toward a tissue within the body of the patient.
