Philips Rolls Out Duo Venous Stent System

Philips announced the first implant of its Duo venous stent system, a device to treat symptomatic venous outflow obstruction in patients with chronic venous insufficiency (CVI).
 
The system is made up of two stents, Duo Hybrid and Duo Extend, in various sizes. Duo Hybrid’s design combines multiple zones of differing mechanical properties into one stent. Due Extend overlaps with the Duo Hybrid to extend therapy. The two stents work together to minimize stent fracture and corrosion risk.
 
They also offer the option to stent in caudal veins with smaller diameters, according to Philips.
 
“Duo is the first stent that offers a differential design for the challenges of venous anatomy—a focal area that withstands the forces of compression as well as the flexibility to accommodate curvature of the vessel,” said Dr Kush Desai, a highly regarded Interventional radiologist and associate professor of Radiology, Surgery and Medicine at Northwestern University in Chicago, as well as a leading enroller and investigator for the VIVID study, which contributed to the device’s recent FDA approval.
 
VIVID evaluated the Duo venous stent system in 162 patients to treat nonmalignant iliofemoral occlusive disease. There were three patient populations in the trial: non-thrombotic iliac vein lesion (NIVL), post-thrombotic syndrome (PTS), and acute deep vein thrombosis (aDVT).
 
The 12-month effectiveness endpoint for primary patency reached 90.2%, exceeding the performance goal of 77.3%. The primary safety endpoint of 98.7% also topped the corresponding performance foal of 89%. Quality of life metrics also showed sustained improvements compared to baseline.
 
“The launch of the Duo Venous Stent System represents another step forward in achieving our aspiration to innovate interventional procedures with advanced medical technology,” said Heather Hudnut Page, VP and business leader of Peripheral Vascular at Philips. “In this context, we look forward to bringing the combined offering of intravascular ultrasound and Duo to the interdisciplinary teams—from vascular surgeons to interventional radiologists and interventional cardiologists—who share our overarching goal of enhancing patient care.”
