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.

ACCESS FROM ANY APPROACH

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.
