Sophisticated 3-in-1 RF wire

Optimized electrode design

The VersaCross RF Wire has been shown to facilitate more consistent site-specific crossing of the interatrial septum, allowing the operator to optimize transseptal puncture location in any anatomy.^2,3,4,5,6 Optimized electrode design and generator settings may improve puncture efficacy, minimize thermal injury, and eliminate embolic coring risk, while the use of electrified guidewires for transseptal puncture has been associated with damage to the guidewire and dilator, as well as risks of thrombus, thermal injury and tissue scaring.^1,7

Published evidence

Reduced risk of complications associated with exchanges

The 3-in-1 VersaCross RF Wire has been shown to facilitate left heart access and therapy sheath delivery with fewer device exchanges than a mechanical or RF transseptal needle-based workflow by serving as a starter wire, RF puncture device, and exchange guidewire.^8,9,10 As a result, the risk of complications associated with exchanges, such as silent cerebral events, may be reduced.^2,8,9,11,12

Published evidence

Reinforced transseptal dilator

TRUform Shapeable Technology

Reinforced with TRUform Shapeable technology, the VersaCross Transseptal Dilator facilitates a familiar handling experience to a needle-based transseptal system and retains your desired curve. Reshape the dilator within your sheath to optimize transseptal assembly positioning for various anatomies.^†,2

Smooth dilator-to-sheath transition

The VersaCross Transseptal Dilator was specially designed to provide a minimal, smooth dilator-to-sheath transition for sleek advancement into the left atrium. The smooth transition between VersaCross Connect™ Dilators and compatible therapy delivery sheaths may reduce snagging on the fossa ovalis during crossing.^†

Dedicated RF puncture generator

Proprietary RF energy waveforms for targeted punctures

The RFP-100A RF Puncture Generator^** was designed to create small, targeted transseptal punctures via the delivery of proprietary RF energy waveforms. The generator enables shorter RF activation time, while built-in safety features limit the voltage, current, and power. Use of the RFP-100A RF Puncture Generator^** with the VersaCross RF Wire has been shown to result in smaller puncture sites and improved transseptal puncture consistency when compared to electrified guidewires or needles.^1,4,7

Published evidence

Comparing ex vivo transseptal puncture sites utilising an electrified needle at 10W, 20W, and 30W, to a successful puncture site utilising the VersaCross Wire at 10W.

Fewer and lower energy applications required

Achieve successful transseptal puncture with fewer and lower energy applications required. In a comparison study, an electrified transseptal needle required 30 W to achieve 91% transseptal puncture success, failing to puncture at 10 W and 20 W, while the VersaCross Access Solution achieved 100% transseptal puncture success with only one energy application of approximately 10 W and zero incidence of tissue coring. Adversely, the electrified needles were associated with tissue charring, larger septal defects and tissue coring in 57% of punctures.¹

Published evidence

Enhanced visualization with OMNIviz Technology

VersaCross Access Solution under fluoroscopy.

Radiopaque

The VersaCross Wire and Dilator are radiopaque so you can visualize your entire solution on fluoroscopy.

VersaCross Access Solution on ultrasound.

Echogenic

Reliably locate your VersaCross Wire and Dilator on ultrasound to reduce or eliminate fluoroscopy time and radiation exposure.^9,10,13,14

Mapping

Connect to the DuoMode™ Cable to track and mark the VersaCross RF Wire’s electrode tip on your preferred mapping system.^‡

Clinical highlights

March 2025, Al-Ahmad et al., published in Journal of Cardiovascular Electrophysiology

Comparison of a guidewire with large uninsulated electrode tip vs. dedicated RF wire with discrete electrode for energy-based transseptal puncture: A pre-clinical study^†

The VersaCross RF Wire and dedicated RFP-100A RF Puncture Generator** achieved 100% transseptal puncture success with only 1 RF application.

100% transseptal success

With only one RF application required. The electrified guidewire required up to five applications and did not consistently achieve puncture.

Lower energy required

Total energy output was significantly lower and less variable than the electrified guidewire.

Reduced risk of thermal injury

Electrified guidewire punctures were larger than VersaCross RF Wire punctures and showed greater thermal damage around the puncture site.

October 2023, Knight et al., published in Journal of Cardiovascular Electrophysiology

Comparison of transseptal puncture using a dedicated RF wire versus a mechanical needle with and without electrification in an animal model
