Left atrial access from any approach™
When the conventional solution may not be optimal, use the SupraCross RF Transseptal Solution to gain alternate access into the left atrium (LA)
How it works
Animation of the SupraCross RF Transseptal Solution, a radiofrequency (RF) transseptal access device for alternate access into the LA
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
High precision SupraCross 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 the navigation of complex anatomy and precise positioning on the fossa4
