NRG® Transseptal Needle

Be Precise. Save Time.™

Improve crossing success rates1-3 and reduce procedure time3,4 with the revolutionary radiofrequency transseptal needle.

The standard for left heart access.

Using radiofrequency energy for your transseptal puncture saves time,3,4 reduces the rate of serious complications,1-6 and increases success rates as compared to mechanical alternatives.

Clinical Advantages

Successfully Cross

Successfully cross difficult anatomies.1 Cross aneurysmal septa while reducing excessive tenting,3 and fibrotic septa while reducing mechanical force.2

Lower Risk

Reduce the rate of serious complications attributed to transseptal puncture, with the use of a radiofrequency needle.1,3-6

Targeted Crossing

Cross the septum at precise locations. Fine tune your position with the rounded atraumatic tip prior to RF delivery.

Save Time

Experience a shorter, more predictable transseptal puncture time.2-4 Reduce fluoroscopy time for transseptal puncture.3,5

Visualize the Needle

Locate the RF needle on your mapping system. Visualize the tip’s exact location with a radiopaque marker during fluoroscopy.

Reduce Skiving

Reduce skiving risk when advancing through the sheath and dilator, with a rounded atraumatic tip.†,5,7
