Why choose the SupraCross RF Solution

Achieve transseptal access using an alternate approach with the SupraCross Steerable Sheath and SupraCross RF Wire

Diagrams of the heart highlighting venous access routes to the left atrium and implying an impaired inferior vena cava.

LA access from any approach

Optimized transseptal approach may be required for these procedures, which have been performed successfully via jugular venous and transhepatic approach in patients with impaired inferior vena cava:

  • Mitral valve repair1
  • Left ventricular tachycardia ablation2
  • Pulmonary vein isolation3,4,5,6
  • Left atrial appendage occlusion7

3-in-1 SupraCross RF Wire

1. Puncture

Cross normal, fibrotic, and aneurysmal septa3,4,8,9
with a short, focused RF energy pulse*

Flexible spiral tip of the SupraCross RF Wire helps to maintain left atrial access.

2. Anchor

Instantly secure and maintain left atrial access with a flexible spiral tip3

0.035-inch stainless steel rail to facilitate sheath exchange with ease.

3. Exchange

Support sheath exchange with a sturdy 0.035" stainless steel rail4

High precision SupraCross Steerable Sheath

SupraCross Steerable sheath with TruGlide handling and flexible dilator.

TruGlide™ handling

Responsive, smooth, high-precision steering to confidently position your curve

Flexible dilator

A fully steerable sheath with flexible dilator to facilitate the navigation of complex anatomy and precise positioning on the fossa4
