GORE® PROPATEN® Vascular Graft, a leading prosthetic vascular graft for lower extremity revascularization, is specifically designed to reduce the risk of acute graft thrombotic failure. With more than a decade of strong performance that includes improving outcomes and reducing reinterventions, this longstanding bypass graft helps deliver both proven clinical and economic value for patients and hospitals.
With more than 10 years of performance, over 600,000 devices implanted, and over 2,000 limbs studied, the GORE® PROPATEN® Vascular Graft is a leading prosthetic bypass graft solution for proven clinical performance and low cumulative cost of care.
GORE® PROPATEN® Vascular Graft
* Overall weighted average primary patency is based on data from 15 peer-reviewed publications meeting pre-determined inclusion criteria.
By substantially reducing acute graft thrombosis within hours after implantation, the CBAS Heparin Surface on the GORE® PROPATEN® Vascular Graft provides clinical benefits that standard ePTFE grafts do not.1
50% reduction in risk of graft occlusion compared to standard ePTFE in critical limb ischemia (CLI) patients.2
Higher primary and secondary patency, and higher limb salvage for below-knee bypass compared to standard ePTFE from 1–3 years.3
Improved clinical outcomes

CBAS Heparin Surface
The CBAS Heparin Surface of the GORE® PROPATEN® Vascular Graft consists of a proprietary covalent end-point bond that preserves the active site, thus retaining heparin’s anticoagulant activity.
