Unites the distinct advantages of the ATS Open Pivot® Heart Valve with leading graft technology for exceptional implantability and proven performance.
PRODUCT FEATURES
- Sizes 21mm to 29mm
Exceptional Implantability
Open Pivot Design
Hemashield® Woven Double Velour Graft from Boston Scientific
Indications for Use
The ATS Open Pivot Heart Valve is indicated for cardiac valve surgery and intended for the replacement of diseased, damaged or malfunctioning heart valves. ATS Open Pivot Heart Valves must be prescribed and ordered by a licensed physician.
Contraindications
There are no known contraindications to heart valve replacement with an ATS Open Pivot Heart Valve for patients who have been determined to be a candidate for mechanical heart valve replacement.

- No tapers, no pleats; allows for easy anastomosis anywhere on the graft
- Larger graft internal diameter minimizes stress on coronary anastomosis
- Rotatable valve allows for optimal leaflet positioning
Open Pivot Design
- No recesses or cavities in the pivot area where thrombus can form1,2
- Continuous passive washing provides for gentle treatment of red blood cells, low level of hemolysis and thromboembolic events1,3
- Unique axis of suspension provides an exceptionally efficient design resulting in leaflet movement responsive to physiological demands and improved hemodynamic performance4
- Solid pyrolytic carbon orifice and strengthening band for thin yet strong orifice and large Geometric Orifice Areas (GOAs) Single plane orifice facilitates valve seating and implant regardless of suture technique
Hemashield® Woven Double Velour Graft from Boston Scientific
- Low porosity graft material improves hemostasis5,6
- Excellent resorption rates facilitate safe, uninterrupted healing6
- Exceptional handling characteristics
