Why choose the SupraCross RF Solution

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

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

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
