Hancock II and Hancock II Ultra 
Bioprostheses
for Heart Valve Replacement

The Hancock II and Hancock II Ultra are for patients who require replacement of their native or prosthetic aortic and/or mitral valves. First introduced in the 1980s, Hancock II is a second-generation valve with more than 25 years of clinical experience.

Overview

Tested, Trusted

Our second-generation bioprosthesis is designed for use in both aortic and mitral positions.

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.

Product Details

30+ Years Delivering Consistent
Performance and Results

With more than 30 years delivering consistent performance and clinical results, you can feel confident procedure after procedure.

  • AORTIC 97.8% freedom from SVD at 20 years*1
  • MITRAL 85% freedom from SVD at 15 years2

 

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:

  • 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
  • Two-step, low-pressure fixation process

Ease of Implant

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.

  • 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 valve-in-valve (ViV) replacements.

  • Radiopaque annulus ring and stent post markers provide visible, distinct guidelines during ViV procedures.
  • MR conditional, nonmetallic frame mitigates risk of corrosion between SAV and TAV stent materials.
  • Interior-mounted leaflets mitigate potential risk of coronary obstruction.
