Royal Philips, the parent company of Philips, announced the first U.S. patient was successfully treated using an intravascular ultrasound (IVUS) system and two new types of flexible stents.
The technology, called Duo Venous Stent, addresses chronic venous insufficiency (CVI) and symptomatic venous outflow obstruction, according to Philips.
It consists of two stents, Duo Hybrid and Duo Extend, of various sizes. Duo Hybrid has a distinct integrated design that combines multiple zones of differing mechanical properties into a single stent. For long lesions, Duo Extend overlaps with the Duo Hybrid to extend therapy. The two stents are designed to work together and minimize the risk of stent fracture and corrosion, while providing an option to stent within caudal veins with smaller diameters, Philips said.

Sanger Heart and Vascular Institute, Atrium Health, in Charlotte, NC, performed the procedure that marks the medical device's launch since U.S. Food and Drug Administration premarket approval in December. Vesper Medical, a wholly-owned subsidiary of Philips, developed the system.
In the announcement, Philips referenced the VIVID study, a global, prospective, multicenter, single-arm, nonblinded clinical trial conducted in the U.S. and Poland. VIVID evaluated the safety and efficacy of the Philips Duo Venous Stent System in the treatment of nonmalignant iliofemoral occlusive disease. Philips noted that the VIVID study was the first clinical trial to mandate IVUS use to aid in lesion assessment and stent sizing prior to device implantation.
![Examples of ultrasound findings and techniques. (A) Images in a 39-year-old male patient with a mass in the left thigh. The mass is heterogeneous on the B-mode US image (compared with the patient in D) and showed increased microvascularity (superb microvascular imaging [SMI]) and shear-wave elastography (SWE) values. Undifferentiated pleomorphic sarcoma was diagnosed at biopsy (with pleomorphic rhabdomyosarcoma in surgical specimen). (B) Images in an 18-year-old male patient with a mass in the left leg. The mass is hypoechoic on the B-mode image, with no other findings suggestive of malignancy. The lesion is in contact with the cortex of the tibia, which is slightly irregular. CT revealed a doubtful anteromedial tibial erosion. The microvascular study demonstrated high vascularization, suggestive of malignancy. Periosteal Ewing sarcoma was diagnosed with both histologic and immunohistochemical confirmation. (C) Images in a 69-year-old female patient with a lump growing on the outside of the left leg. Multiple SWE examinations were performed (please note the high values obtained in the measurements, whereas the color map highlights the stiffness relative to adjacent tissues). SMI showed areas of increased vascularization to target for sampling. Undifferentiated spindle cell sarcoma was diagnosed at biopsy, with residual leiomyosarcoma in the surgical specimen after neoadjuvant therapy. (D) Images in a 56-year-old female patient with a mass in the right thigh. The mass is heterogeneous at both B-mode ultrasound (similar to patient A) and MRI (coronal T2-weighted spectral attenuated inversion recovery [SPAIR]; T1-weighted pre-contrast and postcontrast imaging), which even shows uptake after the administration of paramagnetic contrast material, which is traditionally suggestive of malignancy. Low values at SMI and elastography are suggestive of benignity. Spindle cell lipoma was diagnosed at biopsy, with atypical spindle cell lipomatous tumor in the surgical specimen.](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/08/images-radiol250278fig2.APCFLSvX6p.jpg?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
