Transhepatic 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 via hepatic venous approach.

Alternate Access Solution includes: RF Wire and Steerable Sheath


3-in-1 SupraCross RF Wire

1. Puncture

Cross normal, fibrotic, and aneurysmal septa1,2,3,4 with a short, focused RF energy pulse.

2. Anchor

Instantly secure and maintain left atrial access with a flexible spiral tip1.

3. Exchange

Support sheath exchange with a sturdy 0.035" stainless steel rail2.

Precision Steerable Sheath

TruGlide™ Handling

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

Flexible Dilator

A fully steerable sheath with flexible dilator to facilitate navigating complex anatomy and precise positioning on the fossa2.

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


Successful transseptal access has been achieved by transhepatic approach5,6. Optimized transseptal approach may be required in:

- Mitral valve repair 7
- VT Ablation8
- Pulmonary vein isolation 5,9
- Left atrial appendage occlusion 6

which have been previously performed successfully via transhepatic approach.

* In patients with impaired IVC.
