First launched in 2008 based on the pioneering scientific work of Professor Robert Stegmann and Dr. Murray Johnstone1 – 4, the iTrack™ canaloplasty microcatheter is both an engineering feat and a clinical triumph.
Measuring just 220 microns in diameter – the equivalent of several strands of hair – the iTrack™ comprises a sophisticated set of inner workings including a proprietary guide-wire mechanism that enables it to traverse the full 360° of the canal in a single intubation. It also features a fiber optic for illuminating the distal tip. The iTrack™ also enables you to customize the amount of OVD delivered on an individual patient basis.
“Not only does iTrack™ break the herniations that we see in the canal, but it also viscodilates. So, it’s really pushing out the entire distal channel and also opening up the trabecular meshwork.”
iTrack™ delivers +100 microliters of OVD* over 360° of the canal. As observed via blanching of the episcleral veins immediately following the procedure4, iTrack™ improves flow through the entire conventional outflow system, including the distal portion.
* Testing using a robotically controlled ViscoInjector™ with time-recording mass data to simulate the delivery of OVD over 360° of Schlemm’s canal. Data available upon request.
PRESSURIZEDVISCODILATION
The iTrack™ canaloplasty microcatheter is the only device to deliver OVD into Schlemm’s canal via a patented, pressurized mechanism (Patent No. US7,967,772,B2).
SURGEON-CONTROLLEDDELIVERY
With the iTrack™ canaloplasty microcatheter you can adjust the amount of OVD delivered based on the patency of Schlemm’s canal.
With a flexible design and internal guide-wire, iTrack™ is the only canaloplasty device that can catheterize 360° of the canal during a single intubation.
INTELLIGENTNAVIGATION
A malleable yet rigid internal guide-wire within the iTrack™ canaloplasty microcatheter may minimize the risk of creating an artificial pathway. It also enables you to push through herniations and to maneuver through tight areas of the canal.
PROPRIETARYILLUMINATION
A proprietary illuminated fiber optic tip provides continuous location feedback and helps to safeguard against misdirection of the iTrack™ canaloplasty microcatheter into the suprachoroidal space or the collector channels.
