Methods for fusing a fiber termination

Aspects of the disclosure are drawn to methods for producing a fused connector termination. An exemplary method may include setting a specification requirement to be met by the fused connector termination and applying an amount of heat to a proximal region of an unfused connector termination. The proximal region of the unfused connector termination may include an inner optical fiber coaxially positioned within an outer ferrule, and applying the amount of heat may at least partially fuse the optical fiber to the outer ferrule to form an at least partially fused connector termination. The method may also include imaging the proximal region of the at least partially fused connector termination and determining, based on the imaging, whether the proximal region of the at least partially fused connector termination meets the specification.

Medical laser device and related methods

A laser delivery device may include a connector portion at a proximal end of the laser delivery device and an optical fiber connecting the connector portion to a distal end of the laser delivery device. The connector portion may include a capillary at least partially surrounding a proximal portion of the optical fiber, and the capillary may include dimples on at least a portion of a circumferential surface thereof.

Laser probe tip

A probe tip for communicating and laterally directing electromagnetic radiation comprises a waveguide, a primary capsule, a compressible member and a malleable secondary capsule. The waveguide is configured to communicate electromagnetic radiation and includes a beveled surface at a distal tip for redirecting electromagnetic radiation in a lateral direction. The primary capsule is attached over the distal tip of the waveguide. The compressible member covers a portion of the primary capsule. The malleable secondary capsule is positioned over the primary capsule and the compressible member, and includes a crimp that compresses the compressible member against the primary capsule and secures the secondary capsule to the primary capsule.
