  • Arteriovenous fistula implant effective for inducing laminar blood flow
    Patent number: 10849627
    Abstract: A vascular implant device configured to decrease turbulence in blood flow through an arteriovenous fistula is described. The implant includes an arterial section having a straight hollow tube, a venous section having a curved hollow tube divided into an orthogonal portion at the juncture of the arterial section, a curved portion, and a straight extension portion, and having a continual lumen and lumen surface. The curved portion curves approximately 90 degrees with respect to the arterial section, and the extension portion extends substantially parallel to the arterial section. A plurality of flow-conditioning tabs are located along the lumen surface in arrangements precisely designed to convert the turbulent blood flow that enters the venous section into substantially laminar flow, and to minimize oscillatory shear stress on the venous endothelium as the blood flow exits the device and enters the vein.
