TAV8 Aortic Valvuloplasty Balloon Catheter

Making aortic valve dilation easy.

Unique. Figure 8-shaped balloon is designed to lock into valve anatomy, limiting movement, reducing procedure/ischemic time Safe. Balloon shape maintained throughout inflation reduces likelihood of annular rupture Effective. Enhanced leaflet hyperextension without increasing the risk of annulus over-distension Fast. Rapid inflate/deflate times

The reduction of the bulb lengths provides procedural enhancements over the V8:

  • The 4mm distal bulb segment minimizes balloon engagement of the LVOT and possibly limits conduction disturbances!
  • 15%-20% less inflation volume decreases the time for inflation/deflation, accelerates procedure time, reducing ischemia.
  • The TAV8’s 24mm shoulder-to-shoulder balloon length is 40% shorter than the shoulder-to-shoulder length of a 40mm cylindrical balloon.

And yet this change does not remove the V8 advantages:

  • Mechanically locks into the valve anatomy making Rapid Ventricular Pacing optional in some clinical situations
  • Permits bulb sizing that hyperextends the aortic leaflets into the sinus, increasing the change in aortic valve area, without increasing the risk of excessive dilatation of the aortic annulus.
