Hancock™ II and Hancock II Ultra™
Bioprostheses
The Hancock™ II valve has stood the test of time. First introduced in the 1980s, it has been tested, studied and earned the trust of cardiac surgeons around the world. After dozens of years, and improvements along the way, there are scores of reasons to use this valve with your patients.
Indications
The Hancock™ II and Hancock II Ultra™ are for patients who require replacement of their native or prosthetic aortic and/or mitral valves.
Product details
Tested
Trusted
More than 30 years delivering consistent performance and clinical results, you can feel confident procedure after procedure.
Durability
Published clinical experience demonstrates impressive long-term performance in all age groups for both the aortic and mitral valve.
Additional factors that may contribute to durability are the following:
- T6 (sodium dodecyl sulfate) anti-calcification treatment is applied in order to mitigate the absorption of calcium in the leaflets
- Next generation flexible polymer stent allows for absorption of stress produced during the cardiac cycle
- Low pressure fixation process minimizes septal muscle shelf allowing for improved hemodynamics
Implantability
Our innovative Cinch™ implant system further capitalizes on the valve’s flexible stent to facilitate valve implantation, particularly through a tight sinotubular space. It also:
- Improves overall visualization
- Has stent posts that deflect to allow for easier knot tying near the posts in aortic replacements
- Helps prevent suture looping
- Facilitates minimally invasive procedures
- Protects tissue from inadvertent damage
Maximum flow
The Hancock II valve is designed to allow the maximum amount of blood to flow through it.3
- The sewing ring is mounted flush with the inflow edge of the scalloped stent allowing the bioprosthesis to be positioned completely superior to the annulus
- The internal diameter of the valve aligns with the patient’s annulus allowing for a larger available flow area
- The valve design allows blood to flow through the annulus encountering only tissue, not obstructive components such as the stent and sewing ring
Suitable for future interventions
Valve dimensions and geometry enable future TAV-in-SAV replacements.
- Radiopaque annulus ring and stent post markers provide visible, distinct guidelines during TAV-in-SAV procedures
- MR conditional, non-metallic frame mitigates risk of corrosion between SAV and TAV stent materials
- Interior-mounted leaflets mitigate potential risk of coronary obstruction
