The present disclosure relates to a multi-core optical fiber cable (MCF). In some embodiments, an MCF comprises a plurality of cores surrounded by a cladding and a coating surrounding the cladding, wherein a refractive index of one or more of the plurality of cores is greater than a refractive index of the cladding. The MCF further comprises a probe comprising a probe tip coupled with a distal end of the MCF and a lens located at a distal end of the probe tip. In some embodiments, the lens is configured to translate laser light from the distal end of the MCF to create a multi-spot pattern of laser beams on a target surface and a distal end of the MCF terminates at an interface with the lens.

The present disclosure relates to a multi-core optical fiber cable (MCF). In some embodiments, an MCF comprises a plurality of cores, a cladding surrounding the plurality of cores, wherein a refractive index of one or more of the plurality of cores is greater than a refractive index of the cladding, and a coating surrounding the cladding, a distal end free of the coating and having a reduced diameter. The MCF also comprise an annular gap formed between the distal end of the MCF and the inner surface of the cannula, wherein the concentricity of the distal end of the MCF with the inner passage of the cannula is maintained.

Systems and methods for creating multi-spot laser light beams, multiplexing an illumination light and the multi-spot laser light beams, delivering the multiplexed light to a surgical handpiece via a multi-core optical fiber cable, and delivering the multiplexed light onto patient anatomy.

Certain embodiments of the present disclosure provide a thermally robust laser probe assembly. The probe assembly comprises a cannula through which one or more optical fibers extend at least partially for transmitting laser light from a laser source to a target location. The probe assembly also comprises a lens housed in the cannula and a protective component at a distal end of the cannula, wherein the lens is positioned between the one or more optical fibers and the protective component, and wherein the distal end of the cannula is sealed at a sealing location of the probe assembly.

An intravascular port access device includes a first component having a chamber configured to attach reversibly to an intravenous line port. A second component reversibly attaches to the first component and contains a disinfecting agent and an applicator material. The second component is configured to be reversibly received over external surfaces of the intravenous line port. A method of cleansing an intravenous line port includes providing a port cleaning device having a first component with a chamber containing a first cleaning agent. A second component includes a second cleaning agent. A third component has a microbicidal agent and is reversibly attached to the first component. The second component is removed from the device, the external surfaces of the port are contacted with the second cleaning agent, the first cleaning agent is ejected from the chamber into the port, and the third component is used to cap the port.

A girth weld coating machine has an application head rotatable about a pipeline. A reservoir of coating material is carried on the application head and progressively dispenses coating material on to the girth weld. The coating material is applied to the pipe surface by a roller to spread and distribute the coating over the surface.

A fluid applicator tool that includes an applicator portion including a pair of arcuate clamping members that each include an inner radial portion and an outer radial portion, an absorbent media extending along the inner radial portion of each arcuate clamping member, and a hinge coupled between the pair of arcuate clamping members. The hinge is operable for rotating the pair of arcuate clamping members relative to each other for positioning between an open position and a closed position. The pair of arcuate clamping members are oriented such that a through hole is defined therebetween when in the closed position.

A method for coating a thin film in a rolling manner and a thin film coating apparatus are provided. The method includes: floating a thin film material on a liquefied material; rolling a cylindrical substrate after contacting the cylindrical substrate with the thin film material; and coating the thin film material on a surface of the cylindrical substrate by using an attraction force between the surface of the cylindrical substrate and the thin film material.

An apparatus is provided for applying adhesive to a compressor liner having a longitudinal central axis. A first roller has a longitudinal central axis and has an outer circumferential surface which is immersed in adhesive in an adhesive sink. A second roller has a longitudinal central axis and is radially spaced apart from the first roller. The second roller has same outer diameter as the first roller and has an outer circumferential surface which is not immersed in adhesive in the adhesive sink. The first and second rollers cooperate to support the compressor liner for rotation about its longitudinal central axis. A drive mechanism includes a constant speed drive for rotating the first and second rollers about their longitudinal central axes at a constant rotational speed to allow a consistent weight and uniform layer of adhesive to be transferred from the first roller to the compressor liner.

The present invention provides a preform coating device (10) provided with a cylindrical transfer roller (11) for rotating about a center shaft (111), and an application device for applying a coating liquid in a predetermined thickness to an external peripheral face of the transfer roller (11), the external peripheral face of the transfer roller (11) rotating so as to touch an external peripheral face of a preform (1), and the coating liquid thereby being transferred from the external peripheral face of the transfer roller (11) to the external peripheral face of the preform (1).
