SupraCross® RF Solution

Left Atrial Access from Any Approach.™

Perform transseptal access using an alternate approach, with the SupraCross® Steerable Sheath and SupraCross® RF Wire.

SupraCross® RF Solution (SupraCross® Steerable Sheath and SupraCross® RF Wire) is designed for transseptal access from any approach.

When the conventional solution may not be optimal, use SupraCross® RF Solution to gain alternate access into the left atrium.

3-in-1  SupraCross® RF Wire

1 Puncture

Cross normal, fibrotic, and aneurysmal septa1,2 with a short, focused RF energy pulse.

2 Anchor

Maintain left atrial access with a flexible spiral tip.

3 Exchange

Support sheath exchange with a sturdy stainless steel rail.

‡ Studies used NRG® Transseptal Needle, which employs the same RF puncture technology as the SupraCross® RF Wire.


Optimized transseptal approach may be required in:

- Left ventricular tachycardia ablation 3
- Pulmonary vein isolation 4,5*
- Left atrial appendage occlusion 6*
- Mitral valve repair 7

which have been previously performed successfully via jugular venous approach.

* In patients with impaired IVC.
