Radiofrequency NRG® Transseptal Needle

Radiofrequency NRG® Transseptal Needle

The radiofrequency NRG® Transseptal Needle is uniquely designed to assist the physician in gaining access to the left atrium by using RF energy in a controlled manner as opposed to mechanical force. The radiofrequency NRG® needle uses radiofrequency (RF) energy  in a safe and controlled manner. This allows the physician to advance across the septum in a precise manner without using excessive force.

Radiopaque tip
  • Identify the tip in the dilator
  • View tip in the left atrium
Know exactly where the tip is at all times
  • Visualize the needle tip’s position both inside or outside the dilator
  • Confidently guide the needle throughout the transseptal procedure
  • Provide enhanced guidance when training fellows
Cross thin aneurysmal septa
  • Reduce the need for excessive tenting and risk of needle jump1
Cross thickened, fibrotic septa
  • Reduce the force required1
Faster procedure times
  • Reduce procedure1-2 time
  • fluoro-radiation1 times
No skiving
  • Reduce the creation of plastic particles and the risk of embolization3

    RFP-100A RF Generator

    The Radiofrequency Puncture Generator is different from cardiac ablation generators.  Instead of creating ablations, our generator is designed specifically for creating controlled punctures using radiofrequency (RF) energy.

    TorFlex™ Transseptal Guiding Sheath

    The Torflex™ Transseptal Guiding Sheath is designed to be smooth and controlled. It advances smoothly across the septal tissue into the left atrium,it provides controlled movements in the left atrium due to its high torquability .

    Connector Cable (RFP-102)

    This push-lock connector provides for the quick and easy connection of the radiofrequency NRG® Transseptal Needle to the Baylis Medical RF Puncture Generator.

    BMC Footswitch Pedal

    The optional footswitch pedal allows the physician to directly control the application of RF energy from the RFP-100A RF Puncture Generator.


    The radiofrequency NRG® Transseptal Needle is compatible with standard transseptal sheath & dilator systems. It comes in a number of different configurations. The various curve options mimic those of conventional needles.
