Advancing Coronary Bypass Surgery

with State-of-the-Art Technologies

Evidence Based Developments

Coronary bypass surgery (CABG) is the most performed cardiac surgery worldwide. However, both its short- and long-term outcomes are limited. VGS addresses CABGs’ biggest challenges – the poor longevity of vein grafts and procedure related neurological complications.

With robust clinical evidence over the past decade, VGS’s mission is to advance this standard-of-care surgery while focusing on patients’ quality-of-life and reducing the economic burden to healthcare providers.


Enabling clampless proximal anastomosis

VIOLA novel design allows for optimal hemostasis and construction of multiple aortic anastomoses, without the application of an aortic clamp.

External support for vein grafts in cabg

Randomized clinical trials and real-world data demonstrate that VEST significantly reduces vein graft disease and improves the clinical outcome of CABG.

“The results of the VEST III RCT confirm our previous observations regarding the biomechanical effect of external stenting. This is another peak in our continuous journey to improve coronary surgery and patients’ quality of life. It is very satisfactory to see how a combined effort of surgeons, scientists, and innovators matures to technology with high clinical impact”.
