The Pulsar™ HPC begins inside the surgical laser itself, acting as an extension of the optics train rather than an accessory. InnovaQuartz recognized that the laser’s focal lens could be used as half of a Galilean beam expander if a second, concave lens could be provided by the optical fiber. The input face of the Pulsar HPC is laser-formed concave, with a convex rim about the concavity; we call this a compound annular lens system. The concave center collimates the foal energy like a Galilean beam expander (in reverse) while the convex annulus discriminates between the stable laser output and the unstable, rejecting the latter.

Other features within the termination strip off the rejected energy for dissipation so this potentially destructive energy never enters the fiber. The result is safe transit for energy capable of doing surgical work without bearing the load of highly divergent energy that has no surgical utility.

The ProFlex™ LLF fiber features Smooth Passage™ tips that do not gouge or hang-up in the ureteroscope working channel and do not snap-off.

The ProFlex LLF is available for most holmium lasers that have been cleared for surgical use, including the hard to find, small core fibers for the DEKA Smart 2100 laser and Trimedyne OmniPulse. Sizes available are 150, 200, 273, 365, 550 and 910 microns and most models are available as single use or reusable devices.
