The Bare Fiber is available in several different product variations to perfectly meet a wide variety of requirements and applications. There are different materials and geometries to choose from: from thin and extremely flexible to rigid and durable.

You may choose between the classic flat tip design or alternative shapes like a ball tip, conical tip, spherical tip and more. An integrated handpiece is also available. By catering to a patient’s anatomy on a case-dependent basis, access to the treatment site can be improved and the laser’s energy can be transmitted most efficiently.

Many variations of our Bare Fiber are available, and multiuse versions exist as well. Steam autoclave reconditioning helps reduce expenses on consumables for each treatment session.

Complementary with the Bare Fiber, the Dual LuerLock Handpiece can be used for precise alignment of the fiber tip to the tissue that needs to be treated.

To improve in-coupling of the laser beam into a thin and flexible optical fiber, Tapered Bare Fibers can be manufactured. The connector of such tapered fibers has a larger fiber diameter than the diameter at the distal end. This design makes it possible to couple high-power lasers into the optical fiber safely. The large fiber is tapered down to the target diameter, which is smaller and more flexible so that it is able to reach a remote treatment site.

Lightguide can manufacture taper ratios as high as 4:1 using sophisticated equipment in serial production. For example, our Tapered Bare Fiber can convert a 400 µm beam diameter beam into a 200 µm distal tip at affordable costs. Other typical taper ratios are 2 to 1 and 1.36 to 1. The working principle of a fiber down-taper is illustrated below.

AR Photoniccs Infinity Side Fiber is the next generation instrument for radial laser treatment.

Recent innovations made by Lightguide result in our best laser fiber for soft tissue laser surgery. The broad cylindrical 360° laser light emission of our Infinity Side Fiber ensures smooth and gentle laser energy delivery to the target tissue. Intravascular, intrastitial and intracutaneous laser ablation treatments can benefit from the smoother procedure and higher patient comfort.

The optimized fused fiber tip design guarantees first-class safety and durability. The optical fiber has marking lines to ease positioning in the target tissue. A compatible Introducer Set for vascular access is available.

Fiber optic probes for radial emission

The fiber optic probes for radial emission applications that we produce are optimized for use @1470 nm. This product is particularly suitable for phlebology and gynecology applications where a radial emission of the laser light is recommended.

FIBERS

Our fibers are USP Class VI certified, non-toxic, and biocompatible. Standard products use either a 400 µm or a 600 µm core all silica fiber, to suit different types of lasers and medical procedures.

CONNECTOR

The probe is equipped with the Powershot SMA connector manufactured by SEDI-ATI. This connector is specially designed for power applications of disposable probes where cost issue is important. A free-standing ferrule with an air gap around the fiber allows excellent power handling and the assembly technique avoids any stress on the fiber itself.

DISTAL END

The most efficient design is obtained by a specific shaping of the fiber end which is enclosed in a silica capillary. The result is an annular emission of the laser energy for homogenous action on the vein wall.

JACKET

Ring fibers with a capillary assembly at the distal end are jacketed with a biocompatible material. This jacket has a cm marking to help visualize the fiber introduction in the vein.

MANUFACTURING

• Biocompatible materials.
