Medical technology company St Jude Medical has announced the Japanese launch of a 3D vessel reconstruction system to capture a physiological and anatomical view of the coronary vessels and enable physicians to help diagnose and treat coronary artery disease.
The Ilumien Optis system, which includes a stent planning software tool, combines the PressureWire Aeris Wireless FFR measurement system and intravascular optical coherence tomography (OCT) imaging technology platform.
The FFR measurement system collects detailed analyses of blood flow blockages in the coronary vessels and helps in determining which specific blockages are causing the patient's blood flow to be ineffective, while its FFR pressure guidewire takes measurements through the narrowed part of the artery as it is pulled back.
During the company's FAME clinical trial, the FFR system reduced major adverse cardiovascular events (MACE) in patients whose treatment was guided by FFR, compared to standard angiography alone.
In addition, the FAME 2 study showed that the number of patients returning to the hospital for urgent care was 86% lower for patients with stable coronary artery disease whose stenting procedure was guided by FFR than for those who received medical therapy alone.
Using the Dragonfly JP Imaging Catheter, the OCT technology captures near-infrared light imaging and measures important vessel characteristics that are otherwise invisible or difficult to assess with conventional intracoronary imaging tools.
The FFR and OCT measurements captured by the Ilumien Optis system also allow physicians to more easily differentiate plaque build-up, and determine if the narrowed arteries are causing ischemia, or a restriction in blood flow, ultimately assisting in stent placement, according to the company.
St Jude Medical president William Phillips said; "The new system is the latest in PCI optimisation technology, and helps physicians understand the needs of each patient, ultimately resulting in better medical decision making and overall cost-effective treatment."
