Navitor™ TAVI System

Transcatheter Aortic Valve Implantation (TAVI)

Navitor TAVI System

Smart Sealing.
Exceptional Stability.
Uncompromised Access.

Navitor™ TAVI system offers intelligent design advantages, including smart PVL-sealing NaviSeal™ Cuff, stable and accurate placement, exceptional single-digit gradients,1 and uncompromised small vessel access and coronary access to consistently achieve excellent outcomes across a spectrum of routine to challenging anatomies.

Intelligent Design.

  • NaviSeal Cuff actively synchronizes to the cardiac cycle, seals, and mitigates PVL1 by expanding to fill calcification-related gaps between the annulus and the valve.
  • Non-tapered stent and large EOAs resulting in single-digit gradients are associated with improved cardiac function, long-term durability, and minimal prosthesis-patient mismatch.1
  • The only self-expanding valve with intra-annular leaflets that immediately function and a non-tapered stent, providing hemodynamic stability for a calm and controlled deployment.
  • Exclusive Linx™ anticalcification (AC) technology resists calcification in four distinct ways to improve long-term valve performance.*2-5
  • Large-cell geometry and intra-annular valve design preserve coronary access for future intervention.

Stability and Accuracy.

  • Low profile and highly flexible catheter enables excellent deliverability, even in patients with small access vessels and tortuous anatomies.
  • 14 F** delivery system with 5.0 mm minimum vessel diameter.
  • Controlled deployment provides stable and accurate valve placement.
  • Recapturable,*** repositionable,*** and retrievable*** design.

Excellent 30-Day Outcomes.1

Navitor™ Loading System

Catalog Number 
NVTR-LS-SMThe Navitor™ loading system facilitates valve preparation/loading onto the FlexNav™ delivery system. The loading system includes a loading funnel, loading base, base insert, loading tube, stent guide and leaflet tester. The LG loading system contains an extra base insert to facilitate loading of the 29 mm valve. All base inserts are labeled with the corresponding valve size. In addition, the base insert and loading tube are color-coded to differentiate between the different configurations.

* There is no clinical data currently available that evaluates the long-term impact of anticalcification tissue treatment in humans.
** 14 F equivalent integrated sheath diameter for patients requiring 23 mm or 25 mm valve.
*** Until fully deployed.
