Turbo-Tandem® integrates proven Spectranetics technologies to ablate plaque above the knee, restoring blood flow to the lower extremities. Combining a laser guide catheter with an excimer laser atherectomy catheter, Turbo-Tandem offers physicians the ability to precisely target the lesion. The angled ramp allows for circumferential guidance and positioning of the laser catheter within the vessel, and the spring-loaded handle with variable settings greatly simplifies use of the device for repeated passes through the vessel.
