Overview

Design Expertise

The Mosaic bioprosthesis — based on more than 30 years of Medtronic tissue-valve design expertise — is an excellent choice for surgeons looking for long-lasting durability, exceptional performance and implantability for aortic, mitral, and MICS procedures.

Product Details

Undeniably Durable

Published clinical experience demonstrates impressive long-term performance in all age groups. Additional factors that may contribute to durability are:

  • Proprietary AOA anti-calcification tissue treatment that mitigates calcification and protects the tissue*
  • Next-generation flexible polymer stent that allows for absorption of stress produced during the cardiac cycle
  • Physiologic Fixation process that minimizes the stress applied to the leaflets during fixation*

Excellent  Clinical Outcomes

  • Aortic: 81% freedom from explant due to SVD at 17 years1
  • Mitral: 80% freedom from explant due to SVD at 16 years1

 

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

Advanced Tissue Fixation

Our exclusive Physiologic Fixation* process mitigates biomechanical failures and promotes long-term valve durability by:

  • Improving preservation of valve structure and leaflet function, allowing it to function similar to a native valve
  • Allowing leaflets to remain soft and flexible which protects the tissue from cyclic fatigue
  
  1. Leaflets float at net zero pressure
  2. Roots are pressured at 40 mm Hg with glutaraldehyde

Suitable for Future Interventions

Valve dimensions and geometry facilitate future TAV-in-SAV replacements. This includes:

  • Radiopaque stent post eyelets, which provide visible coaxial markers during TAV-in-SAV procedures
  • MR conditional, nonmetallic frame mitigates risk of corrosion between SAV and TAV stent materials
  • Interior-mounted leaflets mitigate potential risk of coronary obstruction
