Mosaic™ and Mosaic Ultra™
Bioprostheses
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.
Indications
The Mosaic bioprosthesis is for the replacement of malfunctioning native or prosthetic aortic and/or mitral heart valves.
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 allows for absorption of stress produced during the cardiac cycle
- The Medtronic Physiologic Fixation* process minimizes the stress applied to the leaflets during tissue fixation
Excellent clinical outcomes
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:
- Improved 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
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, non-metallic frame mitigates risk of corrosion between SAV and TAV stent materials
- Interior-mounted leaflets mitigate potential risk of coronary obstruction
