Bileaflet Valve

Product Details

Excellent Hemodynamics

In-vivo studies demonstrate excellent hemodynamics.3-5

Easy Implantability

With no tapers or pleats, the Medtronic Open Pivot AVG allows for easy anastomosis anywhere on the graft. A larger graft internal diameter minimizes stress on coronary anastomosis, and the rotatable valve allows for optimal leaflet positioning.

Proven Graft Material

The Hemashield®* Woven Double Velour graft is made with a low-porosity graft material to improve hemostasis.6,7 Excellent resorption rates facilitate healing.6 The graft material also offers exceptional handling characteristics.

Simple Valve Selection 

Convenient accessories include nine white-handled, single-ended standard heart valve sizers. Each sizer handle has a clear cylindrical ring that approximates the patient’s tissue annulus size for appropriate valve selection.
