Abstract: An apparatus includes an optical fiber extending from a proximal end to a distal end. The optical fiber may include a cladding layer circumferentially disposed about a core layer and a substantially spherically shaped portion at the distal end. The apparatus may also include a first coating circumferentially disposed on a first length of the cladding layer, and a second coating circumferentially disposed on a second length of the cladding layer. The second length may extend distally from a region proximate the distal end of the first coating.

Abstract: Embodiments of a medical device and related methods of use are provided for extracting tissue. The device may include an elongate member having a proximal end and a distal end. Two or more channels may extend through the elongate member from the proximal end to the distal end, and a morcellating device may be included in one of the channels. In addition, one of the channels may be configured as a return channel for extracting the morcellated tissue.

Abstract: In one embodiment, an apparatus includes an optical fiber made of a silica-based material. A proximal end portion of the optical fiber has an outer-layer portion. The proximal end portion can be included in at least a portion of a launch connector configured to receive electromagnetic radiation. The apparatus also includes a component that has a bore therethrough and can be made of a doped silica material. The bore can have an inner-layer portion heat-fused to the outer-layer portion of the optical fiber. The component can also have an index of refraction lower than an index of refraction associated with the outer-layer portion of the optical fiber.

Abstract: 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.
