Key Features

Hydra THV


Supraflex Cruz

Hydra Aortic Valve

Outflow Low radial strength
Provides conformability to the shape of the aorta
Mid Frame High hoop strength
Ensures circular configuration of the bioprosthetic valve
Inflow High radial strength
Provides fixation to the native aortic annulus

Marker location and significance

  1. Self-expanding TAVI device to have 2 rows of marker
    • First Markers are located at Node 1
    • Second Markers are located at Node 3
  2. First markers help
    • In precise implantation of the valve at the targeted implantation zone
    • To ascertain the depth of implant
  3. Second markers indicate
    • When the THV leaflets are going to get deployed
Case Example

Hydra AVDC(Aortic Valve Delivery Catheter)

*14F equivalent integrated sheath diameter for patients requiring 22 mm or 26 mm Hydra valve.

Bovine Pericardium

  • Made from single bovine pericardium
  • Bioprosthetic valve leaflets are supra-annular in position, provide superior hemodynamics by providing larger effective orifice area and lower pressure gradient
  • Supra-annular valve position helps to maintain circular shape of the bioprosthetic valve even if the native annulus shape is elliptical
  • Proprietary anti-calcification treatment
