VasQ™
External support for AV anastomosis - VasQ is the only solution currently available that addresses both hemodynamic and mechanical stress to create more usable fistulas.
Promotes Outward Remodeling: The nitinol external support controls remodeling at the anastomosis, promoting outward wall thickening downstream for eventual use in hemodialysis.

Optimal Hemodynamics: Produces a more laminar flow transition, reducing areas of low wall shear stress associated with stenosis or thrombosis.
Mechanical Support: Structurally reinforces the juxta-anastomotic segment, maintaining optimal configuration during the critical weeks of maturation post-surgery.

Venous Tapering: Smoothly transitions flow to the dilated fistula, reducing disturbed flow near the anastomosis.
Arterial Arch: Designed to guide arterial flow towards the vein, ensuring a smooth transition.
Create More Usable Fistulas
In a recent randomized, controlled multi-center study, more VasQ patients used their fistula for hemodialysis and could discontinue CVC use than patients treated without VasQ.
VasQ patients also had a lower incidence of stenosis or occlusion with consistent outward (dilative) remodelling leading to a greater mean diameter as compared to patients treated without VasQ.
The high AVF usability was associated with:
Greater freedom from >50% stenosis anywhere along the access vein (P=.04)
Consistent venous dilation above 6 mm for each patient that led to a greater mean diameter (P = .03)
